The BSM HS model is based on the short-lived early edition British HORNBY-SKEWES unit produced, as used by Ritchie Blackmore, the brilliant and impulsive guitarist of Deep Purple. The unit produces a powerful and biting sound that was used to help create the epochal masterpieces e.g. "Deep Purple In Rock" and "Fireball". The long yearned for new edition, now issued under the name HS from BSM, includes the same germanium transistors as the 1965 version. The HS-Custom model includes a volume control (like Blackmore's modification).
In good condition with the box.
