From the post
The ROG Ginger is an amp emulator designed to sound like the classic Ampeg SB-12 Portaflex. So it's intended for bass, but sounds good with a guitar as well. Schematic, sound clips, and more info can be found in the ROG article. It's laid out for board mounted pots will fit easily in a 125B with top mounted jacks.
