Those are Gotoh's, the exact replacement (D-tuner) would be this one: http://store.hipshotproducts.com/cart.php?m=product_detail&p=72

The next step is to get the remaining 3 matching ultralite tuners. Need to get that neck weight down now that the D tuner experiment works perfectly. It's a keeper and highly recommended, should have put it on sooner. Looking back I should have got the Shiney chrome one like the ones on my Series 2 build .  Now those Gotoh res o-lites are nice looking too, wish they had the A logo on them.
