I didn't realise that hipshot made replacements for the Gotoh GB1 tuners that come on Japanese and some MiM Fender Mustangs, but I saw this new set of HB-10 with lollipops on ebay and I couldn't resist. This type of tuner has a narrower string post than most Fender-type tuners so the HB-10s are the only replacement set for basses using GB1s that don't require any modification to the wood.
They came from a dealer in the US so they weren't cheap. The total cost inc shipping & taxes was £12, but there were no nasty surprises as the taxes etc were paid up front with ebay shipping.
I have just fitted them to my Siennaburst Player Mustang and they feel lovely & smooth like the hipshots on my JMJs and the lollipops look the biz.
