The story is as old as... well your minimoog!: Your minimoog model D is in tune, and you move it to the next room and it's out of tune.... what a drag!

This is because your mini probably has the tuning trimmer's it shipped with.

For mini's with the "old" oscillator card (3046 based, 2 columns of trimmers), the trimmers are very old wire wound trim potentiometers that are affected by even the lightest touch or the capacitance of your screwdriver. They're extremely sensitive, and in most cases are damaged in the track area where the wiper rested for most of its life (the tuning "sweet spot"), which makes it near impossible to tune and scale.

If it's a minimoog with the "new" oscillator card (3 columns of trimmers on rear panel), the trimmers are highly sensitive and as above, probably are damaged around their sweet spot.

Our product creatively adds multi turn trim pots on custom adapter boards that position the adjustment screw on center, so the trims can still be accessed from the rear panel trimming holes.

To make it even more intuitive to use, the adapter board has a duplicate hole set that reverses the trim direction. When these ship, they are configured so sharp is always a right turn, and flat is always a left.

This product includes:

For old oscillator (3046 based, 2 columns of trimmers)
- 3x 1K trimmers for the range adjustment
- 3x 100R trimmers for the scale adjustment
- 1x 100R trimmer for the octave adjustment (marked with sticker)

For new oscillator (726 based with 3 columns of trimmers)
- 6x 10k trimmers for Shift & Scale
- 3x 5k trimmers for Octave adjustment

Installation of this modification requires soldering. If you do not know how to solder at an intermediate level, please defer installation to a competent technician.
