double trouble?

[axis]

Hi all, I posted this question a couple  of days ago and got one reply on it , but I'd like to throw it out again and get so more replies.Has anyone ever used one enclosure for two circuit boards, for example a phaser and a fuzz face in the same box.Each effect would have seperate switches controls etc.Is this a good idea,or no.

I don't think it should be a problem. You might get some interference but I doubt it.

Hi.
I've built in five different circuits in one enclousure.
Works great.

O.K. Thanks for the response guys.

Have you seen the article on "wrappers" at GEOFEX.COM?

I looking for the right enclosure now. I want to go:

1. Dr. Quacky
2. Phase45
3. Orange Squeezer
4. EA Tremelo
5. Stupid Box or Boss SD-1
6. Distortion +
7. Dual Mosfet Booster
8. Amp channel switcher

The Steel Stud thing looks a bit tough to work to me, but the size & price are certainly right!

About 16-18 years ago, I made a rackmount multi-FX box with 7 modules in it, all Anderton circuits or modified versions:

- active splitter
- preamp/EQ (Clarifier circuit)
- compressor
- single parametric EQ section
- envelope-controlled filter
- tube sound distortion
- dual input active mixer
- 2 nondedicated CMOS switching modules

The whole thing was powered by a +/-9v supply and built into a 2U-high Hammond aluminum chassis attached to a 2U rack panel.  

All modules had an in/out toggle switch in the front, and patch points were located on the back, using RCA jacks for space, cost, and simplicity (although  there was a front-mounted phone jack for input and a rear-mounted phone jack for master output).  Any effect could be inserted/patched in any order, and external effects could be inserted as well.  The splitter/mixer combination permitted use of outboard and onboard effects in parallel.  The switching modules could be configured in a variety of ways including in a nested manner (i.e., switch B selects a subset and switch A bypasses a larger set).  The switches were connected to a remote footpedal that had paralleled latching stompswitches and momentary switches, so you could either use the set-and-forget switch to enable a patch and leave it on, or use the momentary switch to patch in a sound for a riff and quickly escape.  The use of a splitter, mixer and completely nondedicated switch (i.e., I could use use inputs without having to use outputs, and vice versa) meant that I could send my guitar to the switch, then to a delay whose wet output would go to a mixer channel.  I could press the momentary to feed the delay, play a riff, then release the momentary so that the clean delayed and recirculated sound would continue to feed the mixer but no additional content would be added to the delay signal.  Of course, since the splitter was a reassignable module, I could split the signal anywhere in the path I wanted to, including post-mixer.

A very smart design, if I do say so myself, and one that I was very proud of.  I sold it off because I needed the money and figured if I could build it once I could build it again.

What you hope to build is certainly feasible.  Given what you plan to have in there, you would be foolish to NOT include a splitter or a means for changing the order of effects, although a "normalized" patching scheme is also a sensible thing to include.  A "normalized" scheme is what traditional analog modular synth would have (e.g., see the Korg MS-20 or MS-50).  In those instances, closed-circuit phone jacks were used.  If you didn't plug anything into them the signal was directed to a default location, but you could override that and redirect simply by plugging in.

Your biggest challenge *and* opportunity, quite apart from the ordering scheme, is switching.  Obviously, unless you intend to go with a big hunk of channeling on the floor, fixed order, and stompswitches, some sort of remote footswitching scheme will be needed.  Some folks will prefer relays, others like FETs and still others will like CMOS switches.  If you intend to use it for gigging, clearly manual switches will not be enough.

What you can do for order changing is use Rean (sp?) jacks.  I believe Colin has some at experimentalistsanonymous.  Wire them so that the effects will cascade with no cables inserted, and then you can use patch leads if you want to change E.g. compression before or after dist.  Simplist way to do it.  I'd use relays for switching myself, but that's just me.

that's the way the CaptainCoconut works.

It is?  Must be a good idea if Foxrox thought of it first.

Nota bene: Normalled insert jacks were old before the first distortion box was invented.
