The 12ax7 in this is wired to the gain knob correct? How much does it really affect the overall tone? What is the stock tube? Will the stock GT12ax7 from my 100t be a better choice then the stock tube in my pro7? Sorry for the 20 questions. Thanks tho!!
I put a GT12ax7 (with red logo on it) in mine last week, cuz I found the JJ to be to much on the muddy side... Not a big difference but there is one, the GT has less gain but cleaner lows and a bit more opened sound than the JJ... Sounds closer to the SVT4 and SVT3 pro I had before. (these had stock GT tubes from the factory in them...) For now, the GT will stay in my SVT7 as it does the trick and is closer to the sound I want. I'll may try a couple of other tube during next weeks and see how they react in the amp.
I will try the tung sol as well, surely next week...
