The Special 6 Ultra's added gain stage provides plenty of overdrive for searing leads, bone-crushing crunch, and gristly grind, while its amazingly effective variable Watts control can reduce the volume to whisper-quiet bedroom practice levels while maintaining the same overdriven tone, texture and dynamic feel.

The Special 6 Ultra features the same unique Volume and Tone controls as the original Special 6, the same footswitchable Boost, High/Low Power switch, and a similarly mod-friendly eyelet board. In addition, the Special 6 Ultra features a unique multi-position Depth control that fine-tunes the low-frequency depth; this feature allows you to carefully voice the amp's low-end to perfectly suit a wide range of guitars, pickups, speakers, and musical styles.

The Special 6 Ultra ships with a 6V6 output tube for sweet clean and rich overdrive tones, and to accommodate tone-seeking experimenters, it can accept a wide range of alternate output tubes. The Special 6 Ultra also features an all-tube buffered effects loop.
