The Full Shred Trembucker (F-spaced) bridge delivers a clear, focused humbucker tone with a nicely balanced treble & bass response, and a backed off midrange. The shorter Allen head poles and alnico 5 bar magnet bring a nice crisp clarity to the high end, while keeping the low end tight and articulate. Great for all types of rock, blues, and metal, and works well in any humbucker equipped guitar with medium to warm tone.Pair with the Full Shred neck model for a well matched setup.Trembuckers have wider pole piece spacing, perfect for symmetrical positioning under the strings of guitars with a tremolo or wide spaced hard tail bridge (2 or wider from the center of the Low E to High E directly over the bridge pickup).
