I put new Sovtech 6L6 tubes in my old Peavey Deuce. I did not get it biased. I don't experience any problems. What is the cost for having it biased? There is a pro shop in Nashville on 250 Cowen which will do it, this shop by the way is located in a warehouse area by the football arena and is home to a very very large recording studio featuring every artist known to man. Neil Young was recording there while I dropped of a practice amp under warrenty. The Peavey Deuce doesn't have a very distinguished reputation, because it is tied in with all of the other Peaveys produced during the 70's. This is the same amp Skynyrd used on tour for One More for the Road. This is arguably one of the top ten albums ever produced. My question is, "Why isn't the Peavey Deuce in high demand, like the Ibanez TS, or 59 Les Paul?" If it produced "swamp tones" and it was a very strong influence in Southern Rock, then why can't I get a Marquee price for it if I sold it? Like $10,000?
