The Supro Keeley Custom 12: The Ultimate Pedal-Ready Amp

Designed in collaboration with Robert Keeley of Keeley Electronics, the Keeley Custom 12 is a powerful all-tube Supro amplifier that seamlessly integrates with your pedalboard. This amplifier takes inspiration from the best-selling Custom 10, delivering exceptional tone and features tailored for pedal enthusiasts. Whether you're a gigging musician or a studio artist, the Custom 12 offers the ideal platform to enhance your sound.

Celestion Creamback Speaker for Vintage Power and Tone

At the heart of the Keeley Custom 12 is the legendary Celestion G12M-65 Creamback speaker, revered by some of the world's greatest players. This speaker offers vintage, woody tone with substantial power, making it perfect for modern amplifiers. It delivers rich low-end depth, warm and vocal mid-range, crunchy upper-mids, and sweet, articulate highs. The Celestion Creamback adds a touch of classic character to your playing.

Perfect Pedal Integration with Transparent Effects Loop

The Custom 12 is designed to be the ultimate pedal platform. It features a transparent effects loop that allows you to inject your modulation effects directly into the all-tube signal path. This ensures that your pedal-generated tones remain clear and free from unwanted distortion. Whether you're adding delay, reverb, or other modulation effects, the Custom 12 provides a pristine canvas for your pedalboard creativity.

Premium Tone, Look, and Feel

This amplifier boasts a Class A preamp with an ECC83S-based tube preamp that delivers ample gain while staying true to the Supro sound. The Class A power section, designed by Bruce Zinky and loaded with premium EHX 6V6GT tubes, delivers the signature Supro tone that's instantly recognizable. The Custom 12 also features a visually stunning design with Custom Blue Rhino Hide tolex, Supro Silver/Blue grill cloth, white piping, a vinyl dog bone handle, and an engraved headplate co-branded with Supro and Keeley Electronics.
