I have just purchased a Rocktron Tsunami much due to the good feedback it has gotten on this forum, and I must say that the sound of it is sweet! However, when I run my active Warwick bass through it, the signal is clipped/distorted, and it seems like the signal from the bass is to hot for the pedal to handle. Does anyone have similar issues? Those of you that own the unit; how do you handle this? Do you only play passive basses? (btw: it is not the battery going dead, I power the unit with an adapter).
