Are F Holes easy to add binding to? I am going to start upgrading my 2420T Streamliner and one of the things I want to do is to add more definition to the F Holes as they are rather anaemic. I will need to take some sand paper and go slowly but whilst I am at it I figured I may as well look at binding them at the same time. What do you guys think? Also replacing the nut; bone or graphite? The other upgrades I am planning are: Gretsch Strap Locks G-Arrow knobs (already got) Chrome Switch Tip (already got) Wilkinson 19:1 Open Gear Tuners Nut replacement HS Filter'Trons (I know TV Jones' seem to be the preferred option, but they are also twice the price) Pot replacement Treble bleed circuit New wiring I may also make a new scratch plate out of some perspex I have laying around, but I haven't decided if I even want one yet. EDIT: I forgot to add Jack Plate (thanks @thunder58) Tru-Arc Bridge By my calculations this should all cost approx £350 and isn't going to happen over night, I have to buy an new organ, PA (or separate amps) and bass first!
