...I've been using my basses straight in to my amp head (Peavey 450 Max) and have occasionally had to get fairly loud in order to be heard. Sometimes the volume is up to the point where the clipping indicator stays lit for longer than my comfort zone allows. Last night at practice, I placed my SABDDI into my signal chain right before the amp's input and used that all night. The result was an incredible increase in loudness without once even approaching clipping. I'm an effects moron, so please explain to me why this happened. An effect can increase volume and not cause clipping? I had to back off of my bass' volume knob by about 50% to get the volume to mix with the rest of the band. Could there be something wrong with the Peavey's preamp?
