ESP J Four Electric Bass Review

Hi there!

Today we are looking at a fabulous ESP bass, a J Four that was built in Japan during the 1990s. This would be similar to the Japan market Amaze series basses. I have owned a few of these over the years and they are to die for. 

This instrument has a wonderful blend of design and styling elements. The body has a jazz bass offset-waist shape, but with sharper horns and deeper cutaways for the virtuoso bassists out there (i.e. not me). The gorgeous ash lumber is sprayed with a layer of trans red that is still in fabulous condition. See the photos for details.

The passive electronics are more traditional jazz bass parts: 2 single coil J pickups and volume/volume/tone controls. 

The neck is a peach, with a pretty rosewood fretboard. The ESP inlay at the 12th fret is a classy touch. It is 1 1/2-inches wide at the nut, and I think it is a bone nut. The truss rod adjusts at the heel, and it works well - the same goes for my guitar.

The hardware is all heavily chrome-plated and is original to the bass. The bridge is a high mass unit, and I believe that it and the tension-adjustable tuners were made by Gotoh. The knurled control knobs are a nice departure from the usual plastic Fender Jazz bass knobs.- 2 have been replaced!

As this bass came from ESP, the overall craftsmanship is impeccable, and the neck is true. The frets are still level and are well-finished on the ends. The pickups have a bit hotter output than the usual Fender Jazz. This is a tremendous rock bass, and quite a looker too. 

These 1990s ESP basses are a great value, and can be found for a lot less cash than comparable Fender products. Check one out if you get the chance.
