Buwico® High Quality 4R Electric Bass Tuners Machine Heads Tuning Pegs Keys Set (Black)

I used these on a three string bass. They are solidly made. The footprint of the back plate is quite large which adds to stability.

The heads on my guitar had worn excessively in a short time, these appear to be of a much higher quality.

They look good, but the ring is too small and it falls and the rest is slighly bigger and not fittind in the old place to replace the old ones.

Guitar rebuild.

They look good but the gears have already started to wear down after about 2 weeks of use

Don't order these. Cheaply made, poor quality and come in a zip lock bag with no packaging or protection. Arrived with paintwork all.chipped and scrapped and amazon advised this is how they always send them. Heads feel flimsy and parts are unfinished with metal bur and sharp parts where they've not been properly machined.
