This set of 2 x 2 Gotoh GB707 bass tuners feature a 1:20 gear ratio for tuning up quickly and accurately. The 'Rock-Solid' string post improves the tuning stability of the tuner and stays strong during bending and tremolo use, special elastic parts eliminate any rattle in the post and transmission of string vibration to the instrument is maximised. The tuners are completely sealed and permanently lubricated through Gotoh's 'Lubri-Coat' technology, a coating applied to the worm gear to ensure better contact between the worm and spur gear wheel, backlash is minimised and durability is increased. 2 x 2 Sets can be used with either right or left handed bass guitars.

replacement for Ibanez Mikro tuners

The Gotoh tuners are a direct replacement for for the standard tuners on the Ibanez Mikro bass. No need to open up or drill screw holes.

Top solid machine heads

Superb finish. They really hold strings and optimize light to heavy gauges tuning stability. They definitely add some sturdiness to your bass and in case of neck-dive it can be compensated by fitting a high-mass bridge from Gotoh, Hipshot or another company.

Ibanez BTB machine head replacement.

Fitted well, found these to be an ideal replacement at a good price.

Beautifully made.

These new tuners have made a massive difference to my bass. It's true one of the old ones was broken so it wasn't hard but all the others were worn and had some play in them. These new ones by Gotoh feel solid as a rock, are incredibly smooth and make tuning a dream. Highly recommended!
