The knobs on that foundation make it worth the extra, those knobs go for a pretty penny. If a T series is missing those knobs its value drops. And the knobs them selves can command a nice price used. Other peavey knobs are not worth much, but I still would have rather have the speed knobs that the seller kept on my fury, replaced with strat knobs, that I will eventually replace with chrome ones. It did not make me grind down his price though . I put the cheap chrome ones from my milestone II on my relic 93 fury, and put the skinny mixer/pedal knobs that were on that fury on the milestone when I sold it. The strat knobs are hard to take off, so I am leaving them on for know.There's one on Reverb right now, but with the $85 fo shipping it seems priced a bit high for its condition.

Wish I had money and was close to the seller, I would jump on that foundation in a heartbeat at $175
