The GB640 is part of GOTOH's Res-o-lite series of super lightweight bass tuning machines heads. GOTOH was able to achieve excellent weight savings by using a special alloy call "duralumin". These lightweight tuning machines are able to help the tendency for bass guitars to "neck dive" and also make long playing sessions more comfortable.
Guitar and Bass tuning machines are described by the side the headstock the machine mounts to when the headstock is viewed from the front. "L" is left side and "R" is right side. Please remember this when placing your order.
This listing is for preconfigured sets. Individual bass tuning machines are available in another listing for a customer looking for a custom configuration or for a replacement tuner.

GOTOH GB640 Tuner Set
I now have these tuners on three different builds and they are fantastic. They retain the look of vintage Fenders, but are super lightweight with a great ratio and feel (no slop or resistance whatsoever as another reviewer mentioned). I've never had issues with the provided screws either, but maybe the other reviewer got bad ones as he suggested.

great color - very weak screws
Love the look of these Cosmic Black tuners and they are super light! I've been building a P bass and these were the last piece of the puzzle. They fit great and look great. BUT.............. The screws that came with these tuners are extremely weak. I drilled pilot holes and was very careful when installing but every screw stripped and one actually broke off in the headstock. I was able to coax most of them out and use the screws from the OEM tuners, but the color obviously doesn't match. Maybe I got a bad batch, but it's really disappointing to spend that much money and have such weak screws.
