Hey, Nick,
The knobs without the pointer will be $21 each. If you want the actual arrow pointer inlayed, i will have to calculate a price. If you just want a position marker dot, add $3/knob. The PU selector teardrop knob with the Myrtle cap will be $26. For a second set screw in each knob, add $1/knob.
I will let you know on the cost of an arrow inlay for the position marker.
Thanks again,
Roger
