Amp Settings
OK, I checked out what I had the knobs on my bass and amp set for. I know an SVT is going to sound different from a 4004, but I think the basic levels should be similar, just not the overall volume. On the amp I set the bass boost button on, treble boost off, bass control at 1:00, Mids flat (using middle position on shape control), treble at 11:00. Volume at noon. On the Sterling I had the treble down a quarter, the mids up about half, and the bass up an eighth (just cracked). This cut through (we didn't mike anything except the kick) really well, but it also allowed the speakers to load and couple with the room so's the wall's were shakin' (as was a lot of booties, gotta love it). Now we were playing "classic rock", a mixture of whatever we thought fit, from Zep to Beatles to Heart and Janis. I think this kind of music needs lots of good old SVT thunder, but my back-up amp is an Eden WT-400 and I have no doubt that it would also provide all the low end needed for a real good time into the 4-ohm load of an SWR 2X10 and 1X15, also at 400 watts (like the 4004). I guess what I'm trying to say here, as gently as possible, is it may be time to get the amp checked out. After careful, although subjective analysis, that's the only thing I can come up with for your problem. Sorry I couldn't be of more help.
