Hi! Actually I'm doing some homerecording with my band. The drum-track is finished and now we gonna start with the bass-lines. We have two ampeg-amps for choice: Ampeq SVT-4 Pro and Ampeq SVT-3 Pro (We also have a good ampeq-speaker) We've heard that 70% of the bass sound should be taken from a DI-Box. My question: Do we need an DI-Box, although we have these amps? Is it better to use a seperate DI-Box? Pleas help us - we start recording today ;-) THANX VERY MUCH!!! bye Phil P.S.: Which one of the two amps would you prefer? P.P.S.: How can I avoid the disturbing "noise" or "squeak"???
