HELP: weird Randall and Sunn Frankenstein amp.
« on: May 21, 2019, 02:39:04 PM »
 Hello all. Im new here and wanted to see if anyone could help identify the Randall half of this amp. I just bought it from someone who told me that the preamp of the Sunn Coliseum bass had been switched out but they weren't sure what replaced it. I opened it up and noticed that the PCB said Randall so i started googling. The controls as far as i can tell seem to line up similarly to a Commander amp. the controls on the Sunn Knobs seem to be Volume, Treble, Mid, Bass, Master(with push/pull pot for gain?). The added Randall pots seem to be Bass, Bass, Unknown, Treble/mid, Treble. Also the Randall knobs go from -10 to +10 which i havent seen on any amps from my internet searches.  Any help would be greatly appreciated. Thanks!
