The Type 1 JB4 is a 4-String pickup set for Jazz Basses with a 'long' sized pickup in the bridge position and a 'short' in the neck position. These pickups won Bass Player's Magazine coveted "Top Tone" award. These pickups feature strong and heavy low end, crisp and distinct upper mids, and a round and open top end that is perfect for Fingerstyle, Rock, Country, Blues, and 70's style Funk.
This pickup uses two pole pieces, and Alnico V magnets to provide the most traditional style of reading your playing known and produce a perfect and linear strong feel.
This pickup set can be distinguished from one another other than dimensions as the bridge pickup has pinkish wire, and the neck pickup has brown wire.
This pickup set is intended for 18.80mm spacing measured over the neck pickup , and 19.80mm measured over the bridge pickup.
Please check the physical size of the pickups you want to replace to make sure the replacements fit properly.
- Length = 3.60"(91mm) Width = 0.73"(19mm)

Aero does not provide screws with their pickups. If you need pickup screws, you can get them on the Pickup Screws page.
Once you go Aero, you don't go back.
I have Aero JB Type I pickups in two Jazz basses now. Just unmatched clarity in a passive pickup.
