Hiwatt SA212 Custom 50 Combo - Brilliant preset

Close · 66/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Hiwatt SA212 is the 2x12 combo version of the 50-watt Custom 50 circuit, with Normal and Brilliant channels and a pair of EL34s. Two 12-inch speakers give it a fuller, louder sound than the 1x12 SA112, and it includes a slave output jack for driving an extra amp. It delivers the classic loud, clear Hiwatt clean with a tight overdrive at high volume.
