Hi, i just tried my amps effect loop and i've noticed that when i play anything with the effect pedal (digitech bp200) there is tons of noise, the light on the gain signals really low input (more than normal) and there is noise/distorsion coming out even if i turn up the pedal volumen to give more gain to the signal on the effect loop it keeps going wrong. I have no clue what is going on. I've tried tones of cables. My equipment if the following: bass--->amp input--->send-->digitech IN-->digitech OUT===>return Left & Return Right jacks in effect loop. My Amp is a warwick protube IV it's new. the effect send is stereo and the return is two mono jack's (left & right). I'm using a Y cable to connect the digitech out to the return in the amp. Also i'm getting really low signal input on the amp, my bass is passive a have the stock MEC Dynamic Correction pups and i have to turn up the gain a LOT! so do u think maybe the Sansamp Bass Driver is a good idea to boost the signal?
