Owned a Valvetronix, AC30CCX, & AC30BM. No interest in other models (yuk!).
The Valvetronix (2 X 12) was cool at first w/ all the effects & stuff but lacked smooth warm tone.
The AC30 Custom Classic w/ Vox Blues was way better but you gotta have an attenuator cuz these are way too
loud. Sounded GREAT w/ a LP or PRS!
The AC30BM is my favorite of the three. Only one knob (volume) but to me this one had the best sound (but not by much). Great w/ LPs!!! Very clear sounding even at high gain w/ an awesome roar. I still own this one. The Vox sound is not for everybody. I love it!
Honestly though, I'm more into Marshalls. Gotta try 'em... only way to judge for yourself.
