I can now supply and install these magnificent upgrade circuits by East-UK!

East produce amazing retro fit preamps that can be dropped directly into the cavities of most standard Jazz style basses as well as  a number of other circuits to suit a variety of instruments.

Having recently fitted a couple of J-Retro and P-Retro circuits I can say that I am suitably stunned by the quality and the value of the units.

As an introductory offer I will supply the units at the list price and fit them for free provided they fit without removing any wood from the body cavities!

John’s products are now in all of my active basses.
