Pedal along the lines of Red Witch Titan (Triple Delay)

[PurpleCatfishBettie]

I've been bandying this about; the idea of a simple, triple delay, and it looks like Red Witch Titan is fairly close to the idea.

A couple of questions though:

1) Could it be as easy as pretty much 'chaining' 3 identical delay circuits in line; instead of having an 'output jack on delay #1', attaching those wires to what would have been the input jack on delay #2, etc.?
2) Assuming 1) were feasible, would you run power to a single connection, then wire that internally to each of the 3 circuits?
3) Where could a person get a custom enclosure for such a thing? Do you guys use drill presses or punch machines for the holes on your pedal creations, or what?


The basic idea is to start with 9 knobs, 3 for each delay in series. 'Time, Mix, Feeback' x 3. It would replace 3 delays on the pedal board, with a single pedal. It could be a 'double delay' or a 'quad delay' as well, but hopefully you get my drift.

I don't know electronics well at all, but am wondering if it would as simple as that.

Yup, that would work. You're basically replicating hooking up 3 individual pedals in series.

The only thing is that pedals would have individual bypass switches, whereas the Titan has a single bypass for all three deleys.
If your delay circuits dont have a built-in bypass, you might need to build a separate bypass 'around' the three of them. They're pretty easy, there's DIY pedal advice all over the place, and that's one of the fundamentals.

You could also include your routing and feedback options, just by adding some judicious switches and/or pots ie switched feedback from the 2nd and 3rd pedals back to the input with

2nd output -> switch -> pot -> first input
final output -> switch -> pot -> first input

You could even give it 3 separate outputs, one from each delay stage and/or 3 inputs, one into each delay stage. Plenty of scope for that sort of thing.

2) Assuming 1) were feasible, would you run power to a single connection, then wire that internally to each of the 3 circuits?

Yeah, that'd be fine.

3) Where could a person get a custom enclosure for such a thing? Do you guys use drill presses or punch machines for the holes on your pedal creations, or what?

Suitable aluminium hammond-style boxes can be got from generic electronics parts suppliers, or DIY pedal specialists (like Small Bear in the US).

Ive got a dremel, so I'd use that, though a proper drill press would be ideal. For aluminium, a manual drill is possible too, though, though harder going.

For something desktop, rather than pedal, laser cut acrylic would do.

Yeah, that's fairly easy. Ive been meaning to do something like this for umpty years myself with a set of 4 pedals. However I'd like more routing flexibility, so want to be able to route the inputs and outputs more, so probably connect everything via banana jacks, rather than hardwire them.

thanks. food for thought.

can definitely envision additional 'routing options' and whatnot (exp/cv pedal support, lfo(s))...

will have to get motivated.

i wonder if something like this would be possible to be crowdsourced, then pay a chinese factory to make 500 of them or whatever..

Yeah, the different routing options via switches would be the fun part. I think you could do the Parallel/Serial thing with a 3PDT switch.

I've been getting enclosures from Tayda. They are clones of the Hammond enclosures (dimensions are the same but they feel a bit different) and they are a lot cheaper.

When it comes to drilling die-cast aluminum I use an automatic center punch and a stepped drill bit like this one. It's still possible to get off center when the bit bites into the metal, so I plan to get a drill press soon.

I think this project would be totally do-able with three simple PT2399 based delays. Tayda has PT2399s at a very reasonable price.
Here is a primer for working with that chip (including some more practical details than you'll find in the data sheet: http://www.diyaudiocircuits.com/tutoria ... alog-echo/

I was pondering this a while back; I have a single PT2399 in my parts box and thought it a bit of a waste just having one in a pedal, three or so with a few routing options like the others suggest could be very cool.

3) Where could a person get a custom enclosure for such a thing? Do you guys use drill presses or punch machines for the holes on your pedal creations, or what?

I do have a drill press but it's kind of lost in my shed (probably behind the barbecue... ) I generally just use a regular power drill with the enclosure securely clamped to the workbench. Pro tip: make sure you have the hammer drive off before drilling aluminium.

Thanks for all of the info! I might just have to bite the bullet and do this. If/when there is a working prototype, then think about crowdsourcing it and getting a Chinese factory to build it.

Another basic pedal might be a 2 overdrive, 2 compressor... OD->Comp->OD->Comp or Comp->OD->Comp->OD

Lol... seems like it would clear out a lot of space on a pedal chain/pedalboard (my pedal chain anyway) to have some 'consolidated' pedals like this...

thanks again...
