expression pedal switcher

is it possible to switch or route multiple expression lines into one expression pedal, or multiple for that matter, from a single box of some kind?
I know about loop master, but not sure he makes stuff for expression pedals.
anybody have any experience with this?

what about a simply Y cable making your EXP pedal have 2 outs....wouldn't that work?

I've seen that work with tap tempo, I bet it would work with expression pedals as well

yah, i can't see why it wouldn't. I'm going to get some connectors and build one!

That won't work, and depending on the design of the 2 pedals being controlled you risk damaging them.
What you need is an
Expressionator which has now been licensed to Mission Engineering:

Ok, why wouldn't it work? EXP pedals are passive.

I think if I am understanding the danger correctly that because each pedal has different input requirements that you would need something to reverse polarity, although I am guessing that if you had two line 6 modeling pedals that they would both function the same way and be ok

i was thinkin about puttin an aby box on a dual expression,but wasnt sure if it was gonna work
would end up bein an expensive experiment,cause i dont really need to control both pedals simultaneously 100% of the time
alot of times it would be the opposite(swell in opposite directions)
but even with something that swelled one up and the other down,theyd be in sync all the time nd thats no good for me
so this is gonna be perfect(lotta foot tappin)
ILF takes the fun out of researching and the exitement of finding what you need when you need it
but you guys save me a hell of a lot of time

My moog exp pedal is simply a TRS jack and a POT.
you CAN use a regular volume pedal as a EXP pedal too - you just need a TRS to dual TR cable. Likely you could even use a wah pedal. Only thing would be the taper of the pot would effect the sweep of the effect.

off topic I have a wah housing, how easy would it be to build it into an expression pedal?
any schematics or pot values I should know about?

simple! gut it - I think it's a 10K linear taper pot you'll need, but i'm sure google would know better....
you could do one TRS jack, and get a balanced cable.
here, i'll quit yapping--->

looks simple. I flipping love this place!!!!
follow up question
what is to stop you from putting to jacks on to control two different things?

^^^^^^
Exactly!

Do it, let me know if it works! I'll let you know if the splitting the signal works!
