P Series
In the '80s, Ned Steinberger came up with a revolutionary guitar design, of which the most noticeable factor is the lack of a headstock.

Buck was impressed with the design and performance, and the Steinberger became Buck's other most-well-known guitar model.

This P series "Mini-Vee" guitar has a wood body and a bolt-on neck made of composite graphite material, which makes it almost immune to weather conditions that can affect tuning. It also is designed so that all the electronics are attached to the pickguard, which makes swapping out electronics simple. Buck has two configurations, one with 2 single coils and 1 humbucker, and the other with only humbuckers.

This guitar is still in Buck's collection.
