I owned a SVT Classic a few years back. I know these heads are workhorses, and my situation wasn't the norm. But I had a lot of problems with my head (no need to go into them), so I ditched it and went with an Ashdown ABM 500 (which is a hybrid). The SVT sounded better, but once I'm playing in the mix, going through a PA, etc, I hardly noticed a difference. I played through an Orange AD200B today and it sounded really nice. Also, it wasn't nearly as heavy as the SVT. It also only has 4 power tubes and after doing some research, tube swaps and bias adjustments aren't too bad (I used to service electrical equipment, so I have an idea of what's going on). My guitarists are always bugging me to go all tube, but they don't understand guitar solidstate is much different than bass solidstate. The only catch is, the head is 2 grand. I'm worried about spending that much on a piece of electrical equipment. At least if my Ashdown were to go boom and was beyond repaid, I could quickly get a used one for $500. Not so much with the Orange. I know Orange is top notch stuff, but that's a lot of money for electronics, which can fault at any time. Also, I'm not one of those people that obsesses over my sound when playing solo. Things sounds a lot different when you're in the mix. I can't decide. Keep the Ashdown (which I currently like), or go with the Orange which I'm sure I'll like more, but I don't know if it will be 2 grand more. Could you all steer me in one direction?
