I have a beautiful 4 stringed Gibson but I'm at a lost how to string it( What Gauge do I use? For the 1st,2nd 3rd and th.) How many Tuning's are there for them, Would love some help from you guy's and Gal's out there. I do believe Anni di Franco plays one. Any one know it's worth these days. it' sits upstairs in it's case and it seems such a shame not to be able to give it a bang every now and again. Thanks for any Help. Phil (Scouse.)
