I hear what you're saying. My main gigging amp is an ampeg vl series, all tube, dirty mean and nasty. I don't have a solid state amp in the house, except for an old Univox U200B bass head.
I've played lots of 800s over the years but the only ones I've really liked have been the modded ones. I also figure the price on those is too high.
I had a plexi back in early 80's and I stupidly let it go. I've kicked myself for that one many times.
I'd like to find a backup for my existing amp, but those vl series don't appear to be here in canada. I know I can bring one up from the states, but truthfully I would prefer to keep the cash in canada. However I just may have too. I've been looking for two years and haven't found another Ampeg VL here for sale.
I've thought about trying a 900 but am torn from what I have read and heard from people, as well as I am a tube bigot myself. I sure appreciate the info and feedback on the 900s.
