History of the 2017 Grampian Type 636 Reverb Unit from Rawson Sparfield
Chris Hewitt had a family member who was involved in Grampian Reproducers Ltd, manufacturing Type 636 reverb units through the 1960s and into the 1970s. In 2017 Chris's business, Rawson Sparfield, built 7 Grampian Reverbs in the exact original style in the original type of boxes to test the market, and they sold straight away to buyers around the world. The trademark for Grampian was registered in 2018, production of Grampian Type 636 reverb units has continued and the Rawson Sparfield Type 636 Reverb is the only official Grampian 636 unit in the world marketplace.
