Alex - Black Cat Bone Guitars.
Value for money.
I've been buying these regularly from Mr W's for about 6 months, they are on most of my builds, and would gladly recommend them to buyers making a CBG or other stringed instruments. Pro's - You are getting a nicely finished set of 6 machine heads for a great price that work well and take only minutes to install. I've never bought a set with anything missing and even though it's subtle, the slight pearloid finish on the white version is a nice touch. Don't have any "cons" to make mention of really, never had an issue with these affordable machine heads. 4 stars not 5 because of course there are better machine heads out there but the value for money here is hard to beat!
