Reeves era
Under the Hiwatt brand, Reeves' customized Sound City L100 amplifiers were renamed the DR103 Custom 100, which would go on to become the company's best-selling amplifier of the era. Reeves originally sold direct to musicians so he could reinvest the profits that would have gone to distributors and music stores back into growing the Hiwatt brand. Ivor Arbiter later sued Reeves, alleging Reeves had stolen Sound City's design; however, when Reeves challenged Arbiter's engineers to explain certain design elements of the amp circuit in court, they could not and the case was thrown out.[5]
Reeves initially built Hiwatt's amps in his garage in New Malden, Surrey, with the help of Doug Fentiman and Reeves' wife, Daphne, but would later move production to a dedicated facility after numerous noise complaints from neighbors.[5] They built amps and cabinets to military specs, and the brand gained a reputation for producing amps that were "built like tanks".[1] In these early years, however, there was a great deal of variation in Hiwatt's amps, as Reeves often took customer requests. Some of his amps even had tone stacks similar to Marshall and Fender designs.[2] Reeves also did contracted work making amps during this time, most notably for Sola Sound.[5]
One of the earliest famous Hiwatt users was Jethro Tull bassist Glenn Cornick. It was at Cornick's urging that the first 200-watt (and later 400-watt) Hiwatt amps were produced, the DR201 and DR405, respectively. Townshend, who worked with Reeves on the Sound City amps, also became a Hiwatt endorser. Hiwatt amps prominently formed his onstage backdrop during The Who's Live at Leeds concert.[3]
With Hiwatt growing in popularity into the 1970s, Reeves hired former band road manager Peter Webber, who used his connections to get Hiwatt amps into the hands of many notable artists. Hiwatt players of this era included David Gilmour, Jimmy Page, The Rolling Stones, and The Moody Blues.[1] By 1971, Hiwatt was struggling to keep up with production, so Reeves hired certified government wirer Harry Joyce to wire chassis for the company.[1] Under Joyce, schematics were standardized, eliminating previous variations in design, and the brand solidified its reputation for producing "big, high-headroom machines."[2] Joyce additionally limited his workload to 40 amps per month in order to maintain high quality standards.[3]
Reeves died in 1981 from an accidental fall down a staircase. At the time, Reeves was in divorce proceedings and the company passed into the control of lawyers rather than Reeves' children, as he had intended.[1]
Descendant companies
After Reeves' death, several Hiwatt employees incorporated as Biacrown Ltd. and continued producing Hiwatt-style amplifiers with minor circuit changes until 1984, when the company folded for financial reasons. The Hiwatt name was later sold to Music Ground in the U.K., while Hiwatt reemerged as a subsidiary of Fernandes Guitars in the United States.[1] On both sides of the Atlantic, Hiwatt amps were subjected to cost-cutting measures that hurt the brand's previously-sterling reputation for quality, which in turn caused Reeves-era models to be more prized on the vintage market. Several manufacturers have since been formed by enthusiasts of vintage Hiwatts to build their own versions to the previous era's specs. Notably, in 2006, Clayton Callaway and Mark Huss partnered with Reeves' son Glynn to found Hi-Tone Amplification in Columbus, Indiana to faithfully recreate Hiwatt-style amps to the production standards of the original brand.[2] In 2018, Andrei Nicula purchased the rights to the Hylight name to manufacture new versions of Hiwatt's amps.[6]
