Designed in collaboration with Robert Keeley of Keeley Electronics, the Keeley Custom 10 is built to seamlessly integrate your pedals into the heart of an all-tube Supro amplifier. The preamp and 2-band EQ section are voiced perfectly for running your gain pedals in front of the amp, while still maintaining Supro’s signature midrange heft and phenomenal touch dynamics. Meanwhile, a transparent effects loop provides the ideal point to inject your delay and reverb effects into the amplifier’s all-tube signal path, avoiding unwanted distortion on modulation effects. A master volume circuit allows you to control the sound pressure level coming from the speaker, while pouring on copious amounts of gain from the ECC83S-based tube preamp or your favorite dirt pedals. The Keeley Custom 10 offers 25 watts of Class A power in a convenient 1x10 format, featuring the Celestion Creamback 10 speaker.

A ECC83S-based tube preamp pours on the gain, while a Bruce Zinky-designed cathode-biased Class A power section loaded with premium EHX 6V6GT tubes achieves the instantly recognizable Supro sound.

Custom Blue Rhino Hide tolex, the Supro Silver/Blue grill cloth, white piping, a dog bone handle, and engraved headplate co-branded with Supro and Keeley Electronics identities.
