"Simple but effective digital reverb"
The Digital Reverb rack effect module is a GT-designed rack reverb based on the Belton "bricks". It loosely compares to other digital spring reverbs, but none in particular.
Our Digital Reverb module is a GT design that doesn't compare to any specific pedal. It is designed around the Belton Digital Reverb family of ICs or "bricks". The nearest comparable pedals would be other digital reverbs using those ICs, or possibly other digital spring reverb pedals.
There are different versions of the Belton bricks based on how they are mounted to the circuit board, the size of room they model, and other features. The documentation for their reverb modules is sketchy at best. They appear to have a fixed "room size" and "dwell", and also seem to include some modulation in the delay. There seems to be some filtering as well. You get to choose from 4 different models that we support. There are 3 different models of their version 2 brick - short, medium, and long. Short, medium, or long seems to refer to the maximum decay time (Dwell), the amount of time you can hear the reverb effect for some sound. But it also makes the room sound smaller or larger at maximum settings. Short is 2 seconds. Medium is 2.5 seconds. Long is 2.85 seconds. Medium is probably most popular for guitar, but any of them will work. It is just a matter of preference. If you want "big" reverb, get the long one.
Detailed info about their version 3 brick is scarce. It seems to have some modulation built into it. The decay time is also supposed to be adjustable from "short" to "long" like the fixed values of the v2 models. But the control seems to be more of a control on the depth of the modulation than the length of the decay time. If you want the Depth control, that requires the v3 brick. And since the only reason to get the v3 brick is for that control, selecting "v3" and the Depth Control option mean the same thing - you'll get v3 with Depth control.
Why choose one brick over the other? Maybe you prefer simplicity of one less control. Or prefer more control. Some players don't need short or long decays that were originally intended for use with other instruments besides guitar. All the versions sound good and have a fair amount of adjustability in them. The v2 "short" gives the least flexibility. The v2 long and v3 probably have more range than you'll need, and can get into that metallic sound at extreme settings. If you want "normal, simple" reverb, the medium v2 might be a good choice. If you are a fan of bigger, stadium reverb, the long v2 might be better. V3 seems similar to the long v2, but with adjustable modulation. You get "wetter", more pronounced reverb with the v2, particularly the long v2. So if you really want to get your reverb on, that's the way to go, even without Depth control. If you want a subtle reverb, you can always dial the v2 down or get the medium or maybe even the short version, but you won't get as many knobs to control it. If you're OK without having the really "wet" reverb and prefer more control over what you have, then maybe the v3 is a better choice. Our preference is the v2 either medium or long without the Tone control. That allows from subtle to stadium reverb. If you prefer the ambiance of a smaller venue with less active walls, or a club filled with people absorbing most of the reverb, then a Tone control and/or the v3 may be a better match. You'll also get a subtle modulation waviness that adds some character. The v3 will give you a thicker sound more than providing a big spatial element to your tone. It is a very pleasing fattening of your tone with some echo added in. It's a bit like using a short Delay to fatten your tone. But you won't be able to get the more over-the-top stadium type reverb from the v3. Of course, there is always the Tube Reverb module instead.
Dwell and Reverb (FX and dry mix) controls are standard. Tone and Depth are optional. All the controls are interactive. If you turn down the Tone, you will lose the highs, which will make it seem like you get less reverb since the lows attenuate more quickly. If you turn down the Depth or Dwell, you will also get less Reverb. But the minimum Dwell setting still contains the amount of Dwell built into the Reverb brick itself. The Dwell control just adds more Dwell when it is in use. Turning Dwell down is really more like not turning it up.
- Digital Reverb - GT original digital spring reverb module
- Brick - Select which Belton brick you would like. The default is the v2 medium brick.
- Tone Control - This gives you a control for a modified Big Muff tone stack. It does not have the mid-scoop of the Big Muff. The lower setting cuts the highs considerably. The higher setting cuts the lows slightly. Overall it manages the highs through a much wider range than the lows. The more you cut the highs, the less Dwell and Reverb you will hear. Overall, the circuit is designed to pass the full range of your guitar signal, including bass. The Belton module seems to filter some lows in the reverb path. The Tone control only affects the wet signal. Other than passing through a buffer, the dry signal is mostly unchanged. Since the Tone affects only the reverb path, you may find it a bit subtle until you get used to it. This is especially true if you back off the Reverb control, leaving more of the dry signal which isn't affected by the Tone control.
- Depth Control - This works only with the v3 brick, and you will get this control automatically if you select the v3 brick.
- Clean/Dirty Switch - This switch gives you the option to add a little dirt into just the wet path of the effect. This is a subtle effect, not a big distortion clipping style of effect.
- Custom Op Amp - We use the TL072 by default, but you can choose another pin-compatible op amp.
- Custom Components - We use metal film resistors and a selection of capacitors that provide good tone and low noise.
