NOTES:
1 - the white wire from the neck pickup connects directly to the red
wire on the shielded cable to the pickup switch. The join is wrapped in
insulated sleeving
2 - the earth wire/screen on the
cables from the pickup switch and both pickups are all soldered to the
body of the active EQ pot
3 - this battery earth connects
to the switch terminal on the (3 terminal) jack socket - the circuit is
completed when a jack is inserted, connecting this terminal to earth.
The active on/off mini switche is DPDT. The volume and tone pots are 500K
log with DPDT pull switches, the active tone pot is a 500K linear pot with a centre detent. The
tone cap C1 is a 0.022 microfarad mylar capacitor.
All the passive components on the PCB are easily available, should any
need replaced - the only
active component is the IC, an LA6358 dual op-amp. These may be
difficult to obtain, and can be directly replaced if needed by an LM358.
The PCB layout and components are identical to those in the second version of the active circuit.
