Hello.
I have a Luke III HH with 2 trim switch for the volume and the boost.
I have a Luke III Starry Night HSS with ... 5 trim switch !!!
What is the use of the other three switches?
They do not appear on any schematic.
Thank you
The solution ...
In 2015 the Luke III preamps started using a universal board that has the 5 trim pots, the P/U COMP & BOOST are the only trim pots valid to the Luke III models. The other 3 will not affect the sound of the Luke III models.
