I bought a Tech 21 (SansAmp) Bass Compactor today on closeout at GC. It's going back tomorrow. It's noisy and cruddy. How can this possibly be? The SansAmp Bass Driver DI and Acoustic DI are superb. At least I now know why it was on closeout. Any others with experience on this? I don't use compression as a rule, but I thought it'd be fun to check it out. Maybe I should run through the dbx-1066 I have in my PA. Oh well.
