Gerlt Technologies makes hundreds of customizable rack effects, at prices comparable to regular guitar pedals.  It's time to dump that pedal board and get Your Tone off the floor!

 

 What We Do

You know them as guitar pedals

We build them as rack effect modules you can customize to get Your Tone

Put several rack effect modules into a 3U rack enclosure

Connect power and audio on the back like guitar pedals, adding connections for remote switching

Add a remote footswitch unit to turn rack effects on and off

Add as many rack effect modules, enclosures, and third party products as you like. Plug in your guitar and amp. Rock it! It's that simple.

Hello, Effects Fans!

Yes, things are going slowly and we’re getting a bit stir-crazy, but we’ve kept busy developing new modules.  Today we announce the FBomb.  The FBomb compares to the preamp circuit of the vintage Echo Plex 3 tape delay effects of several decades ago.  It also compares to pedals based on this circuit, such as the Xotic EP Boost, Catalinbread Epoch Pre, Dunlop Echoplex Preamp, MXR Echoplex Preamp, Chase Tone Secret Preamp, ClinchFX EP-Pre, and others.

As you probably know, the Echo Plex tape delay system was an outstanding effect in its day, even if it was a bit finicky to maintain.  Old units in good repair, or the new modern re-makes available, all command steep prices.  The old units were a bit crude compared to pedals today.  One of the crude features was that they did not have a true bypass when switched off.  The guitar signal still went through a preamp and was affected by other "stuff" in the circuit.  Crude, yes, but lucky.  Players noted that even when the unit was off, their tone still sounded better than without the Echo Plex at all.  There is something magical in that non-bypassed circuit that makes your tone more pleasing.  It's the kind of thing your turn on and leave on all the time.  You might not notice it that much if you leave it on all the time, but try turning it off - noooo!!!

People have been arguing for years about what exactly causes the “magic”.  Is it the FET transistor?  The slight tweaking of the frequencies and phases?  Something else in all those tape recording and playback components?  The internal voltage used?  The vintage components?  We think there are multiple design factors coming together to yield one of those difficult-to-explain happy accidents, sort of like those weird capacitor values in the Univibe.  Whatever it is, players have found it definitely sweetens their tone and can be left on all the time, likely as the last effect going into their amp, the same way people used the original Echo Plex units.

There are numerous Echo Plex style preamp/boost pedals, with considerable variation in their circuits.  That seems a bit odd, since they all attempt to reproduce the sound of a specific, documented pre-amp circuit, but it’s true.  The variants probably sound a bit more alike than they do different, but we've designed our FET Bomb or "FBomb" to compare to a couple of popular variants.

If you prefer a design that is closer to the actual Echo Plex 3 preamp design, making some effort to factor in the effects from the rest of the record/playback circuit, and doing the phase tweaking of the original, then our ThermoNuke configuration is similar to the ClinchFX EP-Pre pedal.  You won't get much boost out of it, but it has that always-on tone polishing going on.

If you prefer a design with more boost, and you don't care about being true to the Echo Plex 3 design as long as you get similar results, you might prefer the Hydrogen configuration, which compares to the Xotic EP Boost.  You can "set and forget" the level and turn it into that always on tone enhancer.

Unlike many of our modules, we don't recommend tweaking this circuit.  It does what it does and needs all the elements of its design to do it.  If you need a little something different, check out some of our other FET boosts:  Sabre, Woody, and Edge Boost.

Either way, “FBomb, yeah!”
