Two fx with one volume control

[gutsofgold]

f I run two effects in a single box, can they essentially both share a single volume pot? Or would the two effects have "mismatched" volumes and need two volume pots to balance them? They are a fuzz circuit and an octave circuit if that matters?

Also... could I run two batteries, one for each circuit? The only problem I foresee with this is that both power sources eventually will "meet" at the enclosure since the enclosure is eventually grounded. Will this cause problems? Two different grounds going to the enclosure?

thanks!

You're gonna want something you can control to balance the effects. If you think you'd want to change the balance for every application then you can just use one pot as a blend and one pot as a volume control. Or, you could set the blend with trim pots inside the box if you don't think you'll want to adjust the balance once it's built.

If you want to 2 batteries for longer operation then go ahead and wire them in parallel and just connect the V+ to each circuit.

Don't worry about grounding 2 circuits together, every effect you have on a pedal board is grounded together through the barrel contact of your guitar cables.

Hope that helps!

that does help, the ground issue makes sense now.

as far as the blend pot goes, do you mean the amount of effect? if so... I don't think I need that. even though I have two effects in one box, I essentially want to run them as if they were seperate boxes, just two effects in series. so I would need two volume pots then, perhaps?
