Exponential Curve for Volume Pedal

I'd find quite useful and interesting that the Volume pedal could be configured to respond to an exponential curve.

I'm using the volume pedal in pre and post- stomps position, and often I find the following:
with the pedal completely resting in heel position, I have to move it very little for the amp to start sounding neraly at full volume (just with less gain as, it's post-stomps).

So by adding an exponential curve response, we'd be able to produce more soft and progressive volume swells when using the volume pedal positioned previous to the stack section.

I think it all depends on what type of pedal you have. The kp1 is smooth.

I have both a Ep1-KP and a SP-25k, getting same results with both, and not being able to produce a smooth volume transition in the lowest range due to them being linear and the situation explained above (pre-stomps pedal position).

Well in my experience, most expression pedals out there are linear, and that's why many manufacturers include different curve responses to a product that uses conventional expression pedals.

That's why I'd like to add such curves, anyone else have found themselves in this situation?

To configurate the response by software could be usefull if you use the Pedal for different application e.g. Wah/Morph etc.

The Volume Pedal funktion is very exponential!
When the pedal is set to 10%, the level is at 1%, that is -40 dB.

It is a natural fact, that only a fraction of the pedal will control the volume, when positioned in front of a gained amp.
Alternative curves would not cure this situation.

Why don't you position the pedal after the amp ("Pre Effects") to configure a Volume Pedal, rather than a "Gain Pedal"?

Thanks ckemper for chiming in!
Well I'm putting it previous to the stack section for the type of sound/effect I want to achieve. If you say there's no actual "cure" for the issue and that curves are actually exponential, I guess I could manage to get a similar effect by morphing gain and volume parameters at the same time.

You can check at the "Pre Effects" position, how the real curve sounds.

What Effect do you want to achieve exactly?

I'm after getting soft volume swells, but also with the added gain change. I like the sound change when using the volume pedal in pre-stomps, but I can't manage to get a smooth volume transition of it in the lowest zone.
Thank you!

So morphing could be the key!
