Hi All, I wondered if anyone had experienced a problem with using expression pedals to control volume. I am using a Roland EV-5 10K ohm linear pot and it is pretty much an on/off device rather than a sweep. I have calibrated the pedal and it looks ok. I have also messed around with the taper control in the volume block (not sure if that's the right thing or not). Does anyone know if it is just an incompatible pedal. I also have a Boss FV-500L but that has the same value for the expression side of it and I would have thought they were pretty industry standard. I have an AA12 and am using the B input (I have no idea why I picked B rather than A, but I did). Also, has anyone had any issues with the switches themselves. I only bought mine in January 2020, haven't event gigged it yet, and I had to have footswitch 1 replaced as it stopped working. It's only just returned (a bit delayed by Covid 19) and I would say footswitch 6 requires you to be very delicate and precise to engage it reliably. Other than that it's a great sounding unit, fantastic small footprint and I hope these are just teething issues. Stay safe everyone.
