This is a high quality set of 24mm full size standard potentiometers with 15mm 1/4 inch round shafts including the 7mm long thread. These are the correct values and type for the Hand wired / rebuild versions of the Marshall JCM800 Pre-amp and Master Volume, Bass, Middle, Treble and Presence controls and are also suitable for use in other Marshall 2203/2204/1959 guitar and valve amplifier hand wired clones and DIY builds using Turret Boards such as the one we stock. These pots have solder lugs and are ideal for a hand wired / point to point circuit, mounting directly on the front panel of the amp chassis. Values supplied in this set are: A1M Log or Audio Taper pots x 3, B250K x 1 and B25K x 2 (A type pots are Logarithmic or Audio Taper and B type pots have a linear characteristic).

Note that they will NOT fit on JCM800 PCB's or other Marshall PCB based amps unless you are stripping out the PCB and upgrading the amp to a hand wired Turret Board based version.
