ESP AM PJ4 Bass w/ Lace Sensors & Active EQ, Trans Red, Japan


+ shipping

Up for sale, an ESP AM PJ4 Bass in excellent condition and in perfect working order. A rare Japan-made ESP bass with a PJ Lace Sensor pickup configuration and active EQ, the AM PJ4 takes the traditional Fender bass platform and utilizes it to great effect. Tonewoods include an ash body, maple neck, and 21 fret slab maple fingerboard, and the bass has a natural authoritative midrange, articulate treble growl and focused low end, strung with roundwound 45-105 strings. Each pickup has a dedicated Volume knob, with center-detent active Treble and Bass controls for a particularly broad tonal range. This ESP weighs 9lbs 3oz and can deliver broad thump or bridge pickup-centric burp and grind with a twist of a knob. We've had this ESP dialed in here at Mike & Mike's Guitar Bar with comfortable action and accurate intonation.

The maple neck has a slender U-shaped profile carve at the nut with full shoulders in every register and more heft as you travel up the fingerboard, measuring .800" deep at the 1st fret and .935" at the 12th. The maple fretboard features original medium jumbo frets which have plenty of meat, showing only faint wear beneath the A and D strings on frets 1-5. Notes fret cleanly up the 34" scale, and the neck is straight with a responsive, optimally adjusted truss rod. The nut measures 1 1/2" in width, and the headstock features black clover button long stem tuning machines with full-size baseplates and a smooth response.

The electronics function as intended, with the Lace Sensor PJ pickup pair wired to an active EQ circuit powered by a 9v battery. Hardware includes an ESP-embossed four-bolt neck plate which shows notable patina, while the black plating on the control plate, knurled knobs and four-saddle top-loader bridge is quite clean. Cosmetic wear on the Trans Red finish includes a few dings on the back and lower bout body edge with some light finish scratches central to the back and minor marks on the treble-side lower bout on top between the control plate and bridge. The neck has a smooth gloss finish on the profile with very faint palm wear on the fretboard edges, extending to a couple small spots on the treble side of the fretboard from frets 1-2.

A Gator gigbag is included.
