Stewart-Mac Donald sells a specialized super glue for repairing fingertips and damaged guitars and guitar parts.
To put it mildly it is a lot of work to play this style.
Stevie Ray Vaughan used the largest gauge strings made, at least ones I am familiar with.
Bending the guitar strings to change a note or tone is abusive to the fingertips of the fret hand.
Some players actually put a drop of glue under the nail before a long hi energy set/ gig starts.
This is a mandatory tool to keep available, like in your gig bag or tool box.
Incidentally, super glue was invented and used in the medical field as ‘surgical cement’ for years before it became a house hold product. Super glue in general can be found almost anywhere.
Because guitar players are specialists, there is a company that sells a unique super glue just for guitar players.
Gauge size is .013″ to .056″, basically the same size as suspension bridge cable.I am a sissy, I use light gauge strings such as .009″ to .046″ gauge.Here is an exclusive tip from the late great Stevie Ray Vaughan.Players like Stevie Ray bend strings use a playing technique where you bend the strings with your left hand, for right handed guitarists that is.Bending strings is quite common today, however there is a fairly serious problem that can occur from lots of guitar string bending that is not a guitar problem. The problem I want to address is cuts on your fingertips and or separation of the fingernail to the fingertip itself. Regardless of whether it is a cut or separation, a drop of super glue solves the problem.I have had this problem occur, and more than enough guitar players who bend strings can testify to this problem. One small drop of glue on the cut or in the separation is plenty to let you finish your set or gig.
