jay-syncro Posted February 18, 2020 Share Posted February 18, 2020 (edited) Stone valve preamp, hand wired in the UK in the 70's I believe. The volume control can be switched in as a signal boost or to drive the front of your amp a bit harder, and the tone control can be varied to go from a deep dub tone (fully anticlockwise) to more bright and zingy (fully clockwise). It's a cool unit, also sounds good with guitar! It comes with the original box but no manual. The photo of the manual was sourced online. £70 👍🏻 Edited February 23, 2020 by jay-syncro Link to comment Share on other sites More sharing options...
