replaced pick up
From the photographs you can see that
it has been well used and altered from its
original state.




One of the pick ups has
been replaced (after a
mysterious swelling began
to appear on the original!).

pick ups
The pick ups have been adjusted with the pole pieces for the
B string lowered and the high E string raised on both of them.
There is also damping material between the 1st and 2nd strings
and, on the bridge, material placed under the 3rd and 4th strings.

tailpiece
knobs
The tailpiece has adhesive marks, probably from fixing contact
microphones. Derek’s first contact microphone being a Barcus Berry
which he used to amplify sounds from behind the bridge.
