Hello there,

I’ve been looking around trying to get the answer to this question for a little while, quite a few people seem to ask it but it never gets answered.
I finally want to get an expression pedal for a couple of my EHX effects, and I tumbled upon the Boss FV500, which is marketed as a volume/expression controller.

Will it do both simultaneously? (Obviously not SIMULTANEOUSLY simultaneously as it’s only one pedal…) For example, imagine this is my setup:
– My guitar goes into the input of the Boss, and say, from the output goes into the regular input on my Riddle/Ring Thing, and at the same time, I have a jack from the Boss Expression output to the Riddle/Ring Thing EXP input… (so in short: there are two jacks going from the volume pedal into both the regular input of the effects pedal, and the EXP input)
What would happen? If the Riddle/Ring Thing was disengaged would the Boss act as volume, and as soon as the Riddle/Ring Thing was engaged would it act as expression?

I’m really curious about this, and I think some other people are too, so it would be nice to figure this out!

Cheers.

Louis
