As someone who likes to play around with pedals, is in general a bit geeky, and likes lots of options, I've often considered something like a Gig Rig, or a Boss ES-whatever, however I can't really justify that amount of expense for something just to save me moving cables.
The idea of building one has been simmering away in my head for a while, and having previously programmed Arduino's and ST ARM processors, along with designing and assembling a few PCBs, I think it is entirely doable.
So the general plan, and goal for this challenge -
- Minimum of 4 switchable loops. I do think 6 will be a lot more useable, however 4 involves a good few less relays, and will still prove the underlying design. I may decide to go for a 6 way design, but won't make a definitive decision until I find out just how complicated the PCB would be.
- Arduino for doing the brains. It's easy to program, and more than powerful enough to handle what is in reality a pretty low speed task.
- Switches. One foot switch for each channel, then probably at least a couple more for altering how things work/react.
- LEDs. So you have some idea what's on, and what's doing/connected to what
- Have at least one basic mode programmed, where loops get added/removed in the order you press the respective buttons.
- (I may add an LCD, however it won't really be needed for the basic mode)
As it stands, all this has just been in my head, so the next step will be to sit down with a pad of paper, and start with my tried and tested process of random doodles complete with illegible scribbles.
