How can I add a "dry output" to a circuit?

[poppyman]

Hi,
A friend of mine would like to have a dry output for the tremulus lune I'm building for him. Is there a simple way to do this without losing any volume or anything?
I tried my luck on the internet, without much results.
Would it work with other circuits?

Here's a basic wiring bypass layout (from GGG) where should I wire the DRY OUTPUT tip?

Thanks in advance

Wouldn't it just go to the input tip? If that affects the volume, maybe throw a simple buffer circuit between the input tip and the dry output tip.

Thanks Tempus, it sounds almost too simple to be working
I'll give it a go.

What's the difference between that Dry Output and bypassing the effect?
If you want two parallel outputs you could use this AMZ circuit with some changes:

1. Use just 2 opamps.
2. Separate the outputs after the 100 ohm resistors. Add a 1uF (or so) to each output and connect one to the FX board input and the other to the Dry Output jack.

I think he wants to have the "wet" signal to a certain part of his effect chain and the "dry signal" to another.

In other words , when bypassed the tremolo would have 2 dry outputs and when engaged, the tremolo would have one "wet output" and one "dry ouput". A bit like some delays or enveloppe filters.

A lot of the big box EH stuff (DMM, Freq. Analyzer, etc) have dry and effect outs. Check out their schematics for some ideas. I believe the input is buffered and the dry is taken off of that.

That's where I looked in the first place and it looked the dry output was connected to an opamp so, yeah I assume it's buffered. I was just hoping there was a simpler solution.

You could make a super simple one on perf or even point to point. Six components . http://www.muzique.com/lab/buffers.htm

They DO look pretty straight forward!
would I just squeeze it between the TIP of the input jack lug and the TIP of the "dry output" jack?

Exactly. Build it on perfboard (or use another method) and connect it to both tips.
And if you get switching noise problems try to use an output cap not above 2.2uF.
