I preferred the H&K Access for the tones I was going for. The biggest caveat is that the clean channel is solid state. I had the Marshall 9001 and ADA MP-1 in college, and liked those as well, but the H&K Access sounded better to me. It's pretty much all I used during the 2000s for gigging, practice, rehearsal, or whatever. I tried a few others, like JMP-1, Triaxis, Mesa Quad, Piranha, IE4, Engl E570/E580, but they didn't displace the Access. I sold it in 2010 or so when I went I ditched the rack. I've had a couple since then, both the original and newer sound modules, but they didn't sound as good. Maybe my tastes had changed.
