Cactus Ampworks is a small, family-run tube amplifier builder based in the Phoenix, Arizona area, founded in 2006 by Chris Gebhart — a longtime guitarist, audio engineer, and former guitar technician for Michael Schenker (Scorpions, UFO, MSG). The company builds every amplifier to order using point-to-point hand-wired circuits and solid poplar cabinets with box-joint construction, emphasizing a vintage-influenced voicing rather than channel-switching or onboard effects.

The lineup spans low-watt combos to mid-power heads, including the 8-watt Jalapeno combo, the Mirage combo and 25-watt Mirage head aimed at country and blues players, the 35-watt Vortex head, and the Kingman 2x10 combo. Cactus Ampworks also builds the Stage Coach Audio Brake — a footswitchable power soak and boost — and the Keg Blaster, a small pedal-format unit. The company has a longstanding partnership with Jensen Loudspeakers and features the Jensen Electric Lightning speaker in many of its cabinets.

The brand sells direct through its own site and through a Reverb storefront branded as "CACTUS AMPS HAND WIRED TUBE AMPS," which is where the shortened "Cactus Amps" name most often appears. The shop positions itself as an affordable boutique option for working players, with most amps built on a three-to-six-week lead time.

Cactus Amps has 1 product cataloged on Equipboard, including Guitar Amplifier Heads.
