Parson Amplification is a builder of handwired tube guitar amplifiers that takes aim at the middle ground between mass-produced heads and high-priced boutique offerings. The amps are assembled on turret board with point-to-point wiring, ceramic tube sockets, and solid-wood cabinets, and have drawn notice in press reviews for tidy internal construction and classic British-voiced tones.

The flagship 1975HW is a 50-watt head modeled on the mid-1970s Marshall JMP 2204, running two EL34 power tubes, a trio of 12AX7 preamp tubes, a solid-state rectifier, and switchable 4/8/16-ohm output. A Handwired JMP 2204 Clone variant has also appeared on the used market. The smaller SL30 is a 30-watt two-channel head built around a pair of 6L6 power tubes, with independent clean and drive channels, each with its own preamp gain and master volume, plus crunch and bright voicing switches aimed at gigging players who want power-tube breakup at stage volume.
