Ok So I love the sound of the jmp-1. And my ada mp-1 just died after 20 something years so now there is a chance to buy a real jmp-1 and i have an excuse to get it. My question is though is it worth it to buy the real one? I have heard from some the gain is completely different from the model vs the real thing among other things like pure tone etc etc. So any opinions is the brit pre close enough or should I get the real thing? What am I missing buy just having the model?
