I've own basses with Grover, gotoh, hipshot ultra lights and schaller M4-2000 tuners. The schallers are awesome and stay in tune forever. For at least six years I've searched and not a single USA retailer carries these. The closest are the M4s which are completely different. Places can order them for outrageous prices but no one carries them. I have to wonder why. Is it no one has had the opportunity to try them? If anyone knows of a USA seller that will order them for me let me know. Also I'm not interested in paying $160 for a set of 4 tuners. I know the price Mr schaller would sell them for so let's say 15% markup from that.
