Starting in the late 1960s, together with Marshall and Vox, Hiwatt contributed to the sonic image popularly termed "British sound".

[3][4] Hylight Electronics also manufactured amplifiers under the Sola Sound brand for the large UK musical instrument distributor Macari Ltd..

Hylight Electronics originally sold direct to the musicians so that they could reinvest the profits that would have gone to distributors and music stores back into growing the Hiwatt brand.

Hiwatt hired former band road manager Peter Webber, who demonstrated, promoted, and sold the company's amplifiers as quickly as they were built.

In 1971, Hiwatt was struggling to keep up with production, so Reeves approached amp designer Harry Joyce to wire chassis for Hylight.
