Humble Amps is a boutique tube guitar amplifier builder that hand-wires its amps in Fountain Valley, California. The company is best known for producing Dumble-style circuits, with offerings including the Overdrive Special ODS 22 and ODS 50 clones built with Mercury Magnetics transformers, and the Overdrive Solo — a variant originally developed as a custom build for producer Greg Wells based on the John Mayer/Keith Urban Dumble circuit.

The brand's Bumble Bee head takes a different angle, rolling three Howard Dumble-designed Fender modifications (the Tweedle Dee Deluxe mod, the Champ mod, and the UltraPhonix Bandmaster mod) into a single low-wattage Class A amplifier. The stock configuration runs two preamp tubes into a single 6V6 power tube for around 8 watts, with a 5U4 rectifier and separate bright and normal inputs; an optional KT88 power section pushes output up to roughly 13 watts.

Humble Amps products are primarily sold direct through Reverb and through JRR Shop, a Southern California dealer that acts as a retail partner for the brand rather than through a large distribution network. The builder's focus is narrow: handwired, point-to-point tube circuits aimed at players chasing the Dumble overdrive and clean voicings without the secondary-market pricing of original Dumble amps.
