Hello all, recently I've been pondering and laying out a DIY option for a junction box with some fun twists.
It would be designed to go under the board and act as the central hub for signal routing. Signal flow as follows:
1. Passive In/Out (For Fuzzes)
2. Buffered In/Out (probably going to use JFET Buffers here)
3. FX Left and Right In from Buffered Out.
4. Tuner Out
5. Left Amp Out, Right Amp Out
6. Misc. Out (TRS Jack to a Multi-Function Remote.)
The twist:
Multi-Function Footswitch Remote that controls an ATTiny in the main box with a combination of presses and holds. Sits on top of the pedalboard (think Goodwood Audio's RMT).
Program Selector (Rotary Switch) on the main box that can determine what the Remote does. Example, P1 mutes the signal, P2 mutes with a 1.5 second hold but is a tap tempo as its main function, P3 mutes with a tap, sums to mono with a hold, etc.
Tap Tempo: This is its own project. One of the main reasons I like using mainstage right now is I can set tempos for all of my digital effects with one button.
Tap Tempo Module would have an in from the main box, and an out to the Remote. 3 mono jacks out going to vibrato, tremolo, delay, or two delays and a vibrato, etc.
I've never used an ATTiny85, but I know it has an ADC which can determine its behavior. I'm thinking that the Rotary switch subs in different pull-up/pull-down resistors to decide the "Program" it's in which determines what action it takes when receiving a shunt to ground from the footswitch.
To implement Tap Tempo in DIY pedals, I know there are a few options available right now, like Taptation, Bontempo, and Scientific Guitartist's implementation. I would want a universal option to implement in DIY pedals that would respond the same way that commercial options do. Also, tremolo, vibrato, and delay circuits are all very different. So having a universal way to augment the rate on all 3 effects types is key. My thought was a digitial pot tied into each effects analog pot. Perhaps an ATTiny as well?
What does it solve? I want an elegant design for signal routing, which a junction box provides, with some quality of life features like 1 footswitch to 3 pedals Tap Tempo, Mute, etc.
Desperate to get feedback on this. Would this be of interest to anyone? Has it been done in a DIY setting? If anyone is interested in this, I'm happy to update as I progress.
