Adding a second output to a pedal

metropolis4 · 02-08-2012, 11:15 PM

Alright, I'm having trouble finding an answer to this, and I can't imagine I'm the only one wondering

How would I go about adding a second, dry, output to a pedal so I have a wet out and a dry out?

Hmm. Seanm's B Blender circuit might be a decent starting point.

If I understand Steve's suggestion correctly, that gives you one output which can be panned from all-wet through to all-dry. To get a wet out and a dry out, as metropolis asks, my first instinct would not be to modify anything but to get one of those really small mixers like a Behringer Xenyx 802.*

Send the guitar to a mixer input and send it out of the mixer 2 ways; l+r, or main+monitor. Send one to your pedal and the other... not . Voila; a wet out and a dry out.

yeah, I know this forum has a bit of a down on the B-word, but their mixers are fine IMO. And there are other brands offering roughtly the same thing. They all cost less than many stomp boxes.

I think if you were to take the Blender's circuit (a buffer) and remove the pot, you'd be able to achieve the end goal. Of course, I am not 100% certain by any means.

That being said, the mixer really sounds like the easy way to go.

Which pedal?

Modulation and delay pedals often have a wet and dry chain mixed together somewhere towards the end, so it's just a simple matter of hacking into that for a dry/wet output. For a dirt pedal you'd want to split the signal with a buffer before it hits the circuit. Nothing to complicated.

Just a note on the mixer idea. When I would do that back when I had a more complex signal chain, I'd get a lot of weird impedance issues with different pedals, my amp, etc. Tone was changed a lot too, due to having to deal with a buffer. You'd provably be better off designing your own buffered mixer for that application.

Just my two cents. Mind you, I haven't used a mixer in my rig for a long time.

The pedal is a Big Muff. I'd like to have two outputs on it, one wet going to the rest of my pedals, the second dry going straight to a second input on the same amp. If possible, I'd rather have it just be a wet/dry out, not a blend knob. So it looks like I'd need to build some kind of buffer to put inside the pedal?

I'd rather not do a mixer, as the whole idea was to have something to split the signal rather than having to add something else to the board.

I'm not 100% sure you need a buffer, but then I'm not sure if just splitting off of the input straight to the dry output is much different than using a Y-cable to split the signal ahead of the pedal.

Since you're not mixing them back together you don't have to worry about matching the outputs...just build a basic buffer and split the signal at the output...one side goes to the circuit, the other to your dry jack.
