I read about all sorts of great amps here and I always wonder if it's all just hype. When it comes to D13 amps, I am now a believer. Wow! I had the pleasure of auditioning a number of these amps this weekend and I was very impressed. Played the FTR 37, RSA 31, Low 17/39, CJ11, and the JRT 9/15. All of them sounded great with my Strat but the 9/15 just blew me away. This was the head and 1-12 cab version. I can honestly say that it had the best sound I have ever heard coming from me. When people in a guitar shop stop what they're doing and listen to me play, you know it must sound good. Usually I'm a hack so it was strange to have these folks compliment my sound. I will be ordering one as soon as I pick a color. More expensive than I'd like but I don't see how I can pass it up.
