Very nice pedal, but there is volume difference between fully wet sound and the standby sound... (a lot of boss octaver pedals have that issue too) Yes you can mod this pedal to solve this, i have soldering and technical skills, but i felt too lazy to do it.
I did weeks, months of online research about bass octavers and also tried a few of them myself... Personally i like a bit of bark in the octaver sound and even volumes, i prefer the MXR bass octave deluxe (M88), Aguilar Octamizer.
