The Delay sounded fine. We did not explore it in detail but we did try a few different presets. Theo also demonstrated the detuning that its capable of. Never heard that before! ;-) Could be useful in a moderate amount. I really like the range of some of these effects. From very subtle to over the top

I did not experiment with it but if you would be able to only make small motions with the expression pedal for tap-tempo -only registering the max value times- than it would be a lot better. It's just the amount of foot motion that concerns me...
