The Keeley Custom 12, a collaborative creation with Robert Keeley of Keeley Electronics, serves as the successor to the best-selling Custom 10. This amplifier is designed to flawlessly integrate your pedals into the core of an all-tube Supro amplifier.

Its preamp and 2-band EQ are expertly tuned for use with your gain pedals, preserving the iconic Supro midrange richness and exceptional touch responsiveness. Moreover, a transparent effects loop offers the perfect insertion point for your delay and reverb effects within the all-tube signal path of the amplifier, circumventing any undesired distortion on modulation effects.

Equipped with the storied Celestion G12M-65 Creamback speaker, which emerged in the mid-1960s and won the hearts of renowned guitarists, the Keeley Custom 12 delivers a classic, resonant tone coupled with substantial power, ideal for contemporary amplifiers. It balances robust low-end tones with a warm, vocal mid-range, crisp upper-mids, and clear, defined highs. The master volume circuit enables precise control over the speaker's sound pressure level while delivering abundant gain from the ECC83S-based tube preamp or your preferred distortion pedals.
