He also developed an amplifier during his sickness, which restricted him from working on a normal basis.
Vox enjoyed much success with The Beatles as endorsers and sales roared through the early 1960s.
Amps were produced and sold solely in England through the early 1960s as well.
Due to financial difficulties in the mid-1960s, Jennings sold Vox to the Royston Group in 1964.
Under new ownership, Vox appeared to be destined for success, especially with the guitar boom of the 1960s and The Beatles as endorsers.
Shortly thereafter Royston was liquidated and Corinthian Securities took over.
This proved to be a bad ownership, as Corinthian had no connection with the previous staff and they discontinued almost all of the amplifiers in the catalog, and the few that remained were manufactured in Japan.Later in 1958, Vox released two new amps without the vibrato that the AC-15 had.In late 1959, Vox released the infamous AC-30 that was designed to compete directly with the popular American Fender Twin.The AC-30 became an unqualified success until the Beatles began using it.The Beatles had been using Vox amps since their inception, and one day Brian Epstein traded in their AC-15s for the bigger AC-30s.But the 1970s had its toll on Vox, as it did with other manufacturers as well.
