DIY version of this?

This guy stumbled across my website and sent me an email the other day. Has anyone ever tried to build something similar to this, only maybe a little less complicated?

I could really use something similar to this, but on a little smaller scale.

Isn't that just a floor version of a Bradshaw or Cornish rack? Looks far more manageable though. That would be nice for the everyday working musican. Presets of different fx combos and the ability to preset the levels is nice.

Seems like the big guns on this forum could do it. No skimping on design or quality components here though.  Looks like a lot places to introduce hum and noise.

I have a box on a smaller scale that was sold by BC RIch. It gave you four FX loops and you could program each of five switches to be any combination of the four loops, or nothing for bypass. It's a great tool for comparing four different TS pedals, which is what I last used it for. It's good if you have a couple of pedals that you always use together and you don't want to be stepping on two pedals.

I thought about building a unit like this gig rig, back when I was in high school. Boss had that Effects Control Center that had a brain that would let you program your pedalboard into it, before multi-effects, and control them from an FC foot controller.

Rodgre, did the BC Rich unit have it's own power supply? Was it pretty quiet?

Yeah, I was thinking that it was something like a floor mounted Bob Bradshaw system... it looks like it is a little more sophisticated, though. At least from the outside. It seems to be a pretty obvious PCB thing.

The only thing I don't like about this gigrig thing is the exposed DIP switches. I do happen to have a handfull of these kinds of switches that I have been trying to put to use for some time now.

I imagine that the potential noise problem could be solved by using a grounded bypass scheme of some sort. I wonder if it uses buffers or not?

Hmm.. I'm sure there would be a way to cook up a reasonably cut down, no display just LED analog FET based version of this thing, although not nearly as complex.

Might be a worthwhile exercise.

It was quiet. Not true bypass, but quiet. It used a regular Boss-style 9v adapter and it had outputs for each pedal in the chain, a tuner out, and a master output control.

I can't find any info on the internet about it, but I know that Analogman was selling closeouts of these years and years ago. I bought mine in '97 for $29.99, but it was actually marked $299.99 tee-hee.

sorry, this may seem a little "stupid"  :oops: , but...

What all this pedals in this thread do  :shock: ?

sigh... yeah. There's one on my bench. Right down to the dip switches.

I only did eight preprograms, instead of what looks like sixteen.

It's absolutely straightforward. It was an early version of the more complete stuff I described a bit in ASMOP. Only I did all the loops as true bypass with relays.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

I thought I remembered reading something along these same lines at GEO. I would be happy with something that has six or eight switches on it - just for my most commonly used combinations.
