EX 1 controls

Post by Marcus F » Sun Apr 28, 2019 12:41 am

Recently bought a 1989 Ex1. I’m struggling to figure out what all the controls do. It is the model with 3 knobs, one 3 way pickup selector, and 2 mini toggle switches. If someone could fill me in on what each control does, especially the mini switches, I would be very happy. Thanks!

The front mini-toggle controls the middle coil (the front coil of the rear pickup pair). It operates in conjunction with the 3-way blade switch. Switching the front mini-toggle up position turns on the middle coil in parallel with whichever coils are activated by the 3-way switch. The middle position on the front min-toggle turns off the middle coil. The down position turns on the middle coil in series with the coils activated by the 3-way switch (creating a classic humbucker sound).

The rear mini-toggle turns on an adjustable frequency boost (+10dB boost). When activated, the tone control varies the frequency being boosted.
