This Alnico 2 Pro Trembucker uses the soft treble attack and low string pull of an alnico 2 bar magnet, combined with a special vintage output coil wind to create a warm, sweet tone that is smooth and full, with tons of natural sustain. The highs are articulate and smooth, and the lows are warm and spongy. This is a great pickup for all types of blues and rock. For over 25 years Slash has been the champion of this pickup and used them exclusively on Appetite for Destruction, which has gone on to become the biggest selling debut album of all time. Pair with the Alnico 2 Pro neck model for a 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 centre of the Low E to High E directly over the bridge pickup). Hand built in Seymour Duncan's Santa Barbara, CA factory, the Alnico 2 Pro Trembucker uses an alnico 2 bar magnet, nickel silver bottom plate, 4-conductor lead wire for multiple wiring options, and is vacuum wax potted for squeal-free performance.
