  • Tuning a Gulbransen E4

    I was going through the tuning sequence on a Gulbransen E4 for a church. When I got to the pedals, I noticed there were two octaves on the pedals. All the other pedals were corrected by tuning the associated coil#1. When I got to the F# pedal, there was a warbling between the two octaves. I looked on the pedal circuit board and do not see an adjustment for the lowest octave. If I tune F# coil#1 to cancel the warbling, I am out of tune with the rest of the octaves. Am I missing something on the pedal circuit board down below? I woould like to help out this church
