Unfortunately, the custom buttons come as an add on purchase and must then be installed yourself.
HOW TO INSTALL HIPSHOT BUTTONS:
We can make the tuning machines with your choice of custom button with a minimum order quantity of 300 individual tuners (50 six string sets).
BUT WHY!?
This is a completely reasonable thing to ask for. It would make complete sense to be able to order a guitar tuner from us with the button of your choosing already installed. Unfortunately, there are some complications that prevent us from being able to do that for you.
Mainly the reason is the variety that we offer. There are about 8,000 different types of tuning machine/button combinations that can be made from our catalog. This represents a huge complication for meeting the demand of all our customers. We are definitely serious about being able to offer this in the future but for the time being, it is not possible unless we are filling a large order. We're sorry.
