Ampeg Super Reverb Amplifier Model R-15-R - Normal preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Ampeg Super 15R was a tube guitar combo amplifier featuring a single 15-inch speaker and built-in reverb, providing a large-cone warmth particularly suited to clean jazz and blues tones. The 15-inch speaker gave the Super 15R a distinctly full-bodied low-mid response compared to 12-inch contemporaries, making it popular with jazz guitarists who valued its deep, rounded character. The reverb circuit added ambient depth without overwhelming the natural warmth of the large-cone sound.
