Best bass tuners I've used so far. Compared to the standard cheap ones you see OEM and on Ebay etc, they are slightly heavier, but well worth it.
Cheap OEM standard = 57g each tuner
Gotoh GB707 = 68g each tuner
In performance, compared to the cheap OEM, it's like the difference between a plastic toy hammer and a real hammer.
Tuning with Gotoh is just *BAM*, job done.
An added benefit to the precision and speed is it makes it easy to quickly drop-tune between songs - quarter turn that sucker, one glance at the tuner display, done. No need for an expensive drop-tune key with these ready.
