Braided tinned copper shield, tinned stranded 22 gauge copper single hot conductor. Best available wire for the restoration of vintage Gibson guitars or for 'retro' clone building projects. Some folks also use this wire for 'input jack to circuit board' connections in tube amp projects and even for vintage style reverb cables. Much easier to work with than plastic jacketed wire. This Gavitt wire is used by Lindy Fralin, Gibson and other esteemed pickup makers.
