Bill from Hipshot emailed me stating that their locking tuners with all the hardwares (mounting nut, washer and metal button) weigh only 33 grams (1.164 oz). Thats about 4 oz lighter than kluson, almost 6 oz lighter than standard Sperzels and about 3.5 oz lighter than Sperzel Soundlok with plastic button. Also about 4 oz lighter than Waverly. That's unbelievably light even for non-locking tuners. The 1:18 gear ratio only makes it even better, for my needs anyway. Anyone currently using them?
