I want to install a SMB 4A pickup on my Sterling Sub 4 bass. The wiring diagrams show 3 100k pots but the the Sub 4 only has 2 tone controls with a 250k and 100k pot. What pots should I use with this pickup/configuration?
Typically, +9v active pickups will be mated to 25k pots. e.g. EMG, some Bartolini models.
The conventional MusicMan approach is passive pickup(s) through a buffered pre-amp and active EQ. The Duncan SMB/STC combination adopts the same approach.
