So I'll so you how to hack it easily. This will probably work with all synths and keyboards with a tune preset.
Step 1: Materials
- X1 50K potentiometer (check your preset pot to confirm value)
- X1 Knob (optional)
- Retro style wood
Step 2: Making Space for the Pot
Then locate and drill a space where the pot will fit comfortable.
With a dremel clean the space around the pot's place so it can fit secure. In my case it was just in a spot where the screw was so crushed the screw place away.
After cleaning procedures make sure your pot fit well enough it can move freely.
Step 3: The Pot Issue
I soldered 3 wires to each terminal, about 15 cm each wire. It was pretty easy to locate the other pot.
I went ahead and destroyed the pot with some tweezers. Remember if you do not destroy the pot you will increase the value:
50 + 50 = 100
Yo have to make sure to eliminate 50K because that is the value needed.
50 = 50
Solder to the original pot terminals, the wires, matching the polarity of the built in pot.
Step 4: Closing It Up
Step 5: Finishing Retro Touches
Step 6: Wrap Up
