I'm especially interested in the GB350 and even more so in the 720. The GB350 is only 35 gramms, making it even lighter than the Hipshot Ultralite (44 gramms) - meanwhile it has fully sealed gears. There's also the GB720, which is supposed to be teh lighter-weight version of the GB7 (it also has aluminium shaft and plated plastic button, like the 350), but I couldn't find much info about it's weight so far. It also costs about half what the GB350 goes for (... never thought I'd spend so much on tuners...) so being as broke as I am now, I'd be quite happy to be able to save those couple of bucks for the finishing of my bass. If they are under 50 gramms, I'm game. So anyone ever seen them? Thanks in advance!
