[quote name='Bassman68' post='760066' date='Feb 28 2010, 07:34 PM']As stated AH stands for amp-head, GP stands for Graphic-Preamp in all their guises...
Just remember as far as power, Trace are notorious for under-rating their outputs especially in their earlier models i.e MKIV, V'S & 6's!
Find one of these models & you're on to a winner, IMO i wouldn't bother with the latter SMX lines when the likes of Gibson etc took over,
although the latest range seems to get great reviews.[/quote]
Careful with your history... Gibson took over after the GP12X preamp, not the SMX preamp, that wa sa Kaman era and widely regarded as the last "good" Trace. Pedantic, I?
