G&L tech resources: Nuts & string retainers

 
 

When G&L released a number of models with a Kahler™ 2320 flat mount fine-tuner vibrato in 1985, a U-shaped bracket was not good enough to provide sufficient tuning stability. Another one of Leo’s inventions came to the rescue: a string lock mechanism behind the nut. It is covered by US Pat. 4,517,874 (filed June 19, 1984) and ensures a proper string angle over the nut (see this Rampage). This clamping mechanism was licensed to GuitarTech and this is the brand name one sees stamped on the plates, together with “Pat. Pend.”. For comparison, check this 3rd style Interceptor HSS for a high-end aftermarket string clamping solution.
