Some left handed instruments have controls that turn anti-clockwise for ‘more’, while other lefty instruments are wired the normal way. The harness sold on FBT can only be wired the normal way due to the right hand taper of the pots we use. You would want to seek out ‘left hand taper’ pots for them to be effectively wired lefty.
