Just got my new SD 30 head on Tuesday, and after spending a couple of hours with it I am STOKED! This is the first new amp for me in a couple of years, and I did a ton of research/ demoing before I pulled the trigger. Amazing amp- love the chimey cleans, especially with single coils. Just sounds beautiful. The "out of phase" positions on my Suhr never sounded so good. Gives me a whole new tonal palette to work with. Kick it to the overdrive section and it just screams. Fat, harmonically rich notes just fly out of this thing. Very juicy and sweet sounding. Power chords sustain then go into sweet feedback, even at lower volumes. Roll the volume back bit on the guitar, and it cleans up very nicely. All in all it seems to be a very versatile, great sounding amp. I'm very happy with it so far- it's exactly what I was looking for. Tonight will be the trial by fire- got a gig, and I can't wait to hear it with my band. Rock on!
