Currently, I am updating my Schecter Elite 5-string. These tuning Keys work great on the Schecter Bass and were a good buy.
They are very smooth and keep control of the tuning. It has made tuning the bass a whole lot easier. Before, my tuner would show a string as being high or low and it was just so hard to get it tweaked in.
Now, if I turn it, it goes up and if I turn it the other way it goes down...very precise...and, I have enjoyed the new set the last few weeks.
