The T-40 is becoming a clasic and prices are rising rapidly. They actualy have a great tone, and would work well in any studio. It's an American made bass. It has historical significance as it was the first mass made bass that was cut with a CNC machien. They also play quite well. The only reason I sold the one I had was due to the weight. She was a beast, and I am obsessed with ultra light weight basses.
I would say get it as fast as you can. You would be traiding a mid level bass for a pro level bass. Don't underestimate the T-40. TalkBass is filled with haters that complaine about any quality bass.
The T-40 dose have complicated controlls that take a while to figure out.
