I have seen and heard amazing boutique amps. I hesitate to pull the trigger, because I worry about the viability of such companies and their ability to provide customer service into the future. I also worry about resale for such an expensive items. Ahh the amp blues. Wisdom? Snide remarks? Non-sequiturs? Edit: let me add, maybe I am asking a lot but many of these amps cannot be tested before purchase. I want to feel like I am covered. I erased the part about mainstream gear, because I do not want to confuse the issue. Right now, I am looking for a marshally sound plexi-jtm like with an fx loop no more than 20-30 watts, as it will be mainly for the studio.
