If you like it, then that's all that matters. I've heard guys sound great on some of the most un-BELIEVABLE TRASH--both guitars and amps.
I think think Peavey builds great gear. They don't get a lot of respect, but Hartley Peavey has done more for the music industry than any other builder in the last four decades. What he did is simply amazing!
I've heard demos of the Transtube Supremes, and come away very impressed with their tube like tones. Peavey stuff is well-built, reliable--and they stand behind their products.
Your tone comes from your heart and soul. When you find that place in your core, the place where the music comes from--the place where you feel the incredible JOY that you get from playing....when you FEEL the power of the music in your soul...it will not matter what amp or what guitar you are playing.
