Hi, there! I just wanted to know if any of you are sitting on some valuable info on this rig I have. I`ve had it for 7 years now, and it`s got a really punchy and room-filling sound, some ground-noise, but thats the only problem with it so far. I like it really well, and it works quite good with my `Wick. Nonetheless, I don`t really know anything about. If it`s known to be great/good/sucky on the market, it`s history, if it`s something I should keep or if thère`s any serious problems with it. Any info is highly appreciated!! It`s a Peavey MarkIV 800watts-head (320w in 2ohm), with built-in compressor. The cab is a Black Widow 400BH. Both from about 1982.
