Reinhardt Amplification is a boutique amplifier shop founded by Bob Reinhardt, who hand-built tube amps and effects out of Virginia. The line is best known for British-voiced designs running EL34 or EL84 power tubes, with each amp built to order rather than mass-produced. Models include the Reinhardt 18, an 18-watt Marshall-derived head and combo praised for moving from sparkling cleans through classic-rock crunch; the larger Storm Series; the Ampzilla, a 45-watt head; and the Titan 36 and SV 18, the latter reviewed in Premier Guitar.

Beyond amplifiers, Reinhardt also produced the Willard, a distortion pedal built around a true NOS LM308N op-amp and inspired by the big-box ProCo RAT, voiced for fuzzier '80s-style distortion with extra clarity and headroom. The combination of small-batch tube amps and a handful of pedals gave the brand a niche following on community forums like The Gear Page, TDPRI, and Gearspace.

Reinhardt amps developed a reputation for tonal versatility, covering everything from pedal-steel cleans to high-gain crunch, and have been associated with players including Mark Knopfler. The shop operated from the mid-2000s into the early 2010s before Bob Reinhardt stepped away from amp building to focus on motorsports engineering, and surviving units now circulate primarily on the used market through dealers and platforms like Reverb.

Reinhardt has 2 products cataloged on Equipboard, including Guitar Amplifier Heads. Their gear is featured by 2 artists, with the strongest followings in Rock and Folk, World, & Country. Notable users include Mark Knopfler and Brendan Benson.
