Our unique dual-pole design delivers increased sustain and lots of upper mids in this hot, bright bridge humbucker pickup. Great for all things rock! This unique Trembucker (F-spaced) pickup combines our patented dual-pole design, an alnico 5 bar magnet, and over-wound coils for a bold, bright tone with an articulate, clear high-end, and a tight, focused low end. The innovative pole setup will noticeably increase your guitar's natural sustain. Your sound will stay clear, and defined at all gain levels. Chords will be up front, and growl, while leads will have a nice glassy quality. Often paired with a PA-TB1n Original Parallel Axis Trembucker or PA-STK1n Parallel Axis Stack in the neck position for versatility. NOTE: 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 inches or wider from the center of the Low E to High E directly over the bridge pickup). Hand made in Santa Barbara, CA, the Original Parallel Axis uses our unique dual-pole design for added sustain, an alnico 5 bar magnet, 4-conductor wire for multiple wiring options, and is vacuum wax potted for squeal free operation.
