Damn, Matsickma, I wish I'd known all that when the auction was open. I run two old Roland speakers from the SPEAKER and the AUX output on my Thunderbass. Could have been fun to have a separate amp in-line to one channel. Just getting a Guild-Harte 2x10 cabinet (doesn't have the original aluminum speakers), looking forward to hearing the combination. Also bought a T1-12 a couple of months ago - sounds wonderful at volume, a little ambient hiss, but a malfunction in the tremolo - the tremolo works, but there's a loud "thump" repeating at maybe 2 Hz.
Thanks - you have a great wealth of useful information, and your writing is clear, concise and complete. It's always a pleasure to see your name against a new posting.
Cheers,
