OK within the last 2 days i read every thread about the sansamp bddi having not enough power to drive a poweramp properly. So thats my problem too, though i like the tubey sound and the slight compression that thing gives me it lacks volume and punch when plugged into my poweramp. I found it to sound alot clearer, punchier and of course louder when put before another pre or head . I understand, that i have to boost the signal somehow but i cant decide what to get. One option i thought off was to plug the bddi into an MXR M-80 and get another clean tone, a mid control and a more powerfull distortion. But in another thread a guy said that a 9V pedal could not provide a sufficient output level no matter what you do. Is this true? Does anybody use the MXR or another 9V PRE/D.I. pedal to drive a poweramp?
