The Pi fuzz rack effect module compares to many, many pedals that are based on the EHX Big Muff Pi. We offer dozens of configurations that compare to many vintage EHX versions, as well as many of the popular clones, knock-offs, and derivatives that are excellent pedals in their own right. Players may be surprised to find that a very large number of pedals are Big Muff Pi circuits that have been tweaked, lightly modified, or outright copied. Look through our list of configurations below and you'll probably be surprised to find some of them are Pi configs. We offer so many configurations and options that you should be able to get the exact Pi you've always wanted, even if it was never built before.
Description
The Electro Harmonix Big Muff Pi is one of the most popular pedals of all times. It is also probably the most-copied, most-cloned, and most-modified effect circuit of all times. It's decades-long history is a tale in itself, far beyond what we will attempt in any way here. To find out pretty much anything that is known about the Big Muff Pi, you must visit Kit Rae's Big Muff Pi site. Just search for his name and "Big Muff" and you'll find it. In fact, you will probably need to visit his site if you plan to choose one of our Pi configurations. We use his naming convention for some of the many Big Muff Pi (BMP) circuits.
While the BMP has been almost continuously in production for over 40 years, the core circuit design has remained intact. The different versions of the pedal differ mostly in component types and values used in the circuit. On top of the large number of intended different versions, many, many other versions were actually manufactured using slight different component values when the intended components were unavailable. As a result of all the intended and unintended different versions (many dozens), it is difficult to differentiate between them in any way other than getting into specific technical components that were used. In some cases, there is a rough correlation between circuits and the enclosures, colors, and graphics. In other cases, there were just too many variants to even define a typical tone or sound profile to them.
Almost as soon as the first BMP hit the market, other companies started copying and cloning them. This practice continues to this day. Many players may be unaware that a large number of popular pedals are really BMP circuits inside. More modern derivatives have included a dizzying array of modifications and options to add into the mix of circuit variations. We support a very wide variety of these circuits on our Pi board. Since we support them all on the same board, it is possible to mix and match mods, options, and original circuits in ways not normally possible to create your own BMP variant. It may be tempting to end up with a GT Pi module with a dozen or so controls, as opposed to the normal three controls. We recommend not getting carried away. Many of the options do similar things, or would counteract each other. It's probably best to consider picking a BMP circuit that you like, or one you almost like, and then add mods or options to get you from there to the BMP you want. If you have a specific BMP circuit you would like, but don't see a configuration for it, let us know. There are undoubtedly many other versions we can build on our board.
One version of the BMP, did not use the same circuit design. Instead of the normal 4-transistor design, it used op amps to create a completely different fuzz circuit. The only relation it has to the BMP is its name. Everything else is different. We offer that version separate as our IC Pi.
Please note that there are many opinions about the various versions of the BMP circuit and magical components they may use. GT, as well as numerous other effects builders, have found that you can produce outstanding BMP effects using all current production parts. You definitely do not have to use uber-rare and expensive components to get great muff tones. It is also true that the variations from one "identical" unit to another may result in tones that are more different than the tones of two distinctly different variants. Many of the component differences between versions are very small, and could well be swamped by parts value tolerances. While the variations are different, almost all are going to sound like Big Muffs.
Configurations
The tables below show the various configurations we offer. The "V1" table has original Triangle circuits. The "V2" table has original Ram's Head circuits. The "V3 - V9" table has original Tone Bypass, Russian/Sovtek, and the V9, which was the first version when the BMP was brought back to the USA from Russia. Note that the V4 and V5 Op Amp Big Muff Pi circuits are offered separately as our IC Pi. We don't presently offer the newer versions of the BMP. The "Derivatives" tables list a number of BMP derivatives, clones, and copies that we offer our versions of. In the tables we list some of the key parts of each circuit so you can see how they differ. Any Original Circuit name that begins with KR is a reference to one of Kit Rae's circuit configurations at his Big Muff Pi site. Components and features shown in the table are the defaults that will be provided with that configuration. Other options, mods, and components are available as Options.
The diagram below shows the base BMP circuit, labeling some parts. These parts are referenced in the Configuration tables and Options, and can also be used to describe customizations you may want.

Options
Some of our Options are a bit techy, intended for Big Muff Pi aficionados who want very specific Big Muff configurations. You will probably need to look at schematics of various Big Muff Pi circuits and understand what the various components do in order to fully understand how those options work.
We obviously have many options available for this circuit. The number of combinations, particularly considering the number of base configurations you can apply them to, is an extremely large number. We cannot possibly test all those combinations. We cannot tell you what they would all sound like. Some options are physically incompatible because they impact the same part of the circuit. If you select incompatible options, we will catch that during the order process. There are probably lots of other mods we can support beyond the ones listed here. If you have something in mind, just ask and we'll take a look to see if we can build it on our boards.
Some configurations include some options by default. If you do not want those options in your configuration, let us know and we can remove them. We may have to replace them with something else, so we'll consult with you about the replacements. Usually, the price won't go up to omit an option. In some cases, the price may go down, particularly if controls or switches are being removed.
It may be tempting to pile on lots of options to get the ultimate tweaker's Big Muff. We can certainly add quite a number of them. Generally we don't recommend that, though. Many options add switches, connectors, pots, or other components that will eventually fail with normal usage. You don't want to add lots of potential failure points. Even though we take steps to reduce the introduction of noise in the circuit, adding lots of wired options will likely increase noise. The more controls you have, the more difficult it is to dial in a particular tone. It's best to figure out what which circuit you like, then select options that will give you useful variations of that circuit.
If you are thinking about multiple different configurations, think about the differences between the two configurations. Perhaps we have options that could be added to one configuration that would give you the second one, too, or at least close to it. That may have some $$$ and a bit of space in your enclosure.
- Custom Components - By default, we use metal film resistors and a variety of capacitor types to provide lower-noise tone. In specific circuit configurations, we try to use compatible capacitor types to the original circuits, when we know what they are, and if there was a specific type used consistently. We do not try to match brands and styles - just technology and value. Since there are so many Big Muff variations, this option can be used for a variety of purposes: custom transistors, custom clipping diodes, component types, component values, etc. You can basically design your own Big Muff by picking a base config and then using this option to specify individual components (refer to diagram above for component position names).
- Carbon Comp Resistors - We can switch the metal film resistors to carbon comp for those that prefer them. This is often a good choice in fuzz circuits, or at least that's our opinion.
- No Stage 1 Bypass Capacitor - Normally there is a bypass capacitor on the input stage of Big Muff circuits. This is often left off in Tonebender versions of Big Muff circuits. This option leaves it off.
- Stage 1 Bypass Capacitor Switch - This option gives you a switch. One position has no input stage bypass capacitor, the other has whichever bypass capacitor is used in the selected base configuration (or some other value of your choosing).
- Bypass Capacitors Switch - The feedback capacitors are a big factor in the overall tone of a particular Big Muff circuit. They are found on the first three stages, although sometimes there isn't one on the input stage. The configuration tables above show values used in various circuits. Lower values allow more treble through, providing a more aggressive fuzz. Larger values decrease the highs, providing a smoother fuzz. The same size capacitor is normally used in all three stages. Putting in different values has the effect of averaging the values, so usually just pick the value you want. But you're free to choose different values. Some Big Muff circuits have few differences other than these capacitors. Some of the Sovtek Big Muffs are that way. If you pick one of the Sovtek versions and use this option to put the feedback capacitors of another version on the switch, then you can effectively switch between two different Sovtek versions - a twofer. Or if you have a favorite Big Muff circuit but would like to add a smoother or more aggressive flavor to it, you could do that with this option. However, this option will provide little or no audible difference if you capacitor values are similar. For example, switching between 430pF and 470pF is less than a 10% difference. That can easily be lost in a fuzz. Capacitor values usually have a larger tolerance than that, too. That means they could end up being exactly or almost exactly the same with random-choice caps of a particular value. We recommend you pick capacitor values with a bigger difference. Because of the possibility of tolerances messing up the whole point of this option, we will test a pretty large number of individual caps to get them close to the values chosen. That helps ensure that the difference is there. We cannot ensure that you can hear the difference if they are close values, though. This can be affected by other tone-sculpting options.
- Clipping Diodes Switch - This option lets you choose between two different clipping diode configurations of your choice. A third switch setting can be added for no clipping diodes. You can do this for either of the two clipping stages or both. You can have one switch for each stage, or a single switch that switches both stages together. This option is for a single switch. If you want two switches, add this option to your configuration twice.
- Clipping Diodes Blend Control - This is like the Clipping Diodes Switch, but instead of a switch you get a potentiometer that adjusts the ratio between the two clipping configurations. You can do this on one or both of the clipping stages individually, or have a single control which blends both stages at the same time. This option is for a single control. If you want two controls, add this option to your configuration twice.
- Cornish Switches - This option adds the DiceWorks Muff Diver Finale Cornish Switches to other Pi configurations. There are two switches, giving you four different coupling capacitor configurations.
- Creamy Dreamer Mod - This is the mod made popular by the Sustain Punch Creamy Dreamer.
- Creamy Dreamer Switch - We don't presently have the ability to fully switch on/off the Creamy Dreamer Mod. But this mod lets you switch on/off most of the Creamy Dreamer mod, giving you the gain portion of the mod.
- Input Level Switch - This mod lets you switch between two input levels. You can select the second one to be higher or lower than the default level in your circuit config. This is useful if you have a circuit that is overloaded by hot pickups or doesn't have enough push with low output pickups.
- Input Capacitor Switch - This lets you change the input filtering to filter more or less highs out of the input. You can choose to filter more or less than the default level in your circuit config. Can use this to let in more bass (too much can get mushy/flubby/woofy) or filter out more bass to get a more aggressive sound. This can be affected by other tone-sculpting options.
- Input Capacitor Blend - Blend between two input capacitors (one high, one low) to give more control over the incoming bass content. This can be affected by other tone-sculpting options.
- Tone Stack - Several of the Big Muff variants have a different tone stack design. They may use the standard Big Muff tone stack, just tweaking the values of the components. Or they may use a different design altogether. In addition to the standard Pi tone stack (used by the majority of the configurations), the following configurations have slightly different tone stack designs: Egyptian Pi, British Pi, OD-850 Pi, OD-9 Pi, Pickled Pi, Supa Pi, and Dirt Pi. You can select any of those alternate tone stack designs. Doing so puts you into a custom configuration, which may be exactly what you want. But you can also tweak values in the default tone stack for your configuration to perhaps stay close to the sound of that configuration. This option is not presently switchable.
- Tone Bypass - Don't want a Tone control or tone stack at all? No problem. We can leave it out completely.
- Tone Bypass Switch - Gives you a switch to go around the tone stack in your configuration. Your Tone control will do nothing when this is on, and will work normally when it is off.
- Mids Switch - The standard Pi tone stack is mid-scooped. This gives you the ability to switch between scooped, flat, or boosted.
- Nuclear Mids Control - Add a variable Mids control like the one in the Nuclear Pi configuration.
- Boosted Mids Control - Add a variable Mids control like the one in the Boosted Pi configuration.
- Buffer - This option adds a buffer that is on or off when the effect is on or off. You can choose the buffer type from our buffer modules.
- Always On Buffer - Adds a buffer that is always on, whether or not the effect is on or off. You can choose the buffer type from our buffer modules.
- Switched Buffer - Adds a buffer that is switched on/off independently of the effect. You can choose the buffer type from our buffer modules.
- Input Boost - Add a Sonic Boom boost in front of the effect. Also adds a Boost Level control.
- Output Boost - Add a Sonic Boom boost after the effect. Also adds a Boost Level control.
- Switched Input Boost - Add a switchable Sonic Boom boost in front of the effect. Also adds a Boost Level control.
- Switched Output Boost - Add a switchable Sonic Boom boost after the effect. Also adds a Boost Level Control.
- Remove Option - Use this option to tell us about removing an option that you don't want that is included by default for your selected configuration.
