Have bought a new budda sd 45 series 2 and thought i would share my thoughts.
So far in my search for tone i have gone
Koch powertone 2 - 3 channel, great cleans, no real output tube distortion, but quite nice for heavy stuff
Bad cat hot cat 30r - To begin with blown away but gradually found it was not for me, easy to get a bad sound, quite limited tones, not quite loud enough
cornell plexi 45/50 - couldn't dial it in, didnt really like bass response and didnt take pedals as well as i thought it would, probably could have done with more time with it but sold quite quickly.
Bogner ecstatsy 101b - Found a little too compressed and while sounding very very good didnt have the magical vibe i thought considering the price tag. Maybe a little polite in the midrange also
budda sd 45 - really like the rhythm channel, vox like, nice break up, loves pedals. The lead channel has the most amazing clarity, complexity in the mids, bass is quite tight through correct cab ie bogner 4x12 v30's. And although killer loud seem to be able to get output tube distortion easily. as everybody seems to point out very transparent so fingers need to be precise! Only negative is sheer volume, so an attenuator maybe next investment. Also loop is the best i've heard, if anybody has any suggestion for a multi effects unit that sounds good through the loop of the sd45 give me a shout.
I cant imagine anybody being disappointed with this amp, unless you don't like mids as it cuts like a knife but still sounds warm and rounded, for me perfection!
