Hi people! I got my SVT back from the shop the other day (bought it and took it to get it checked out before I cranked it up), plugged in my 4001 (with bartolinis) and turned it up. It sounds fairly distorted, even at relatively low volume (9 O'clock on the volume, all tone controls flat). I'm playing through two 8-ohm Eden 410XLT's with the tweeters at around 10 O'clock. The tech that checked it out has a very good rep, and he said nothing was wrong with it; he even played through it for an hour or two. He just looked it over and biased it up, said it was good to go. So I figure the barts in my Rick are overdriving the preamp, does this sound like a fair assumption? The only thing that seems strange is that I have to turn the volume on the bass WAY down to get a clean sound. I didn't think these old Ampegs had such a high preamp gain? Don't get me wrong, I love a good SVT overdrive, but I like the overdrive to come from the power tubes, know whatta mean? Advice?
