I am trying to come up with a system where I can use an expression pedal to control the level being sent into the pedal in conjunction with the volume of the dry signal – not necessarily just a Wet/Dry blend. For instance, I want to be able to have an expression pedal where the toe down setting is normal wet and as I move towards the heel position, the level of dry signal being fed into the effect is reduced, and the dry signal is increased, but wet signal stays consistent so that way any tails can linger and I can still hear my dry signal without having to reduce the mix to 0 (and thus losing the tails).
To put it another way, I want the expression pedal to control how much of my input signal is being sent into the effect without altering how much dry level comes out of the pedal.
Any ideas on how can I do that?
Thanks!
