KAY and ENGELHARDT BASSES: Serial Number Lists
Recent News and Updates
BONUS - $200+ Value with Purchase of Standard NXT Bass
For a Limited Time - get an amazing Traditional Bass Upgrade kit for FREE with the purchase of a standard model NXT bass!

This package, worth well over $200, provides the "Traditional String Set" that I've long advocated for a more realistic "upright bass tone," as well as the lightweight and durable Hipshot US-made Ultralight tuning key set, which is a recommended upgrade for any NXT that has the stock tuners. These are very commonly purchased items by owners of the NXT bass, and I'm giving them to you for FREE -- but only for a limited time!

Get our Accessory Bag for only $20!
Our popular backpack/shoulder carried gig bag (for accessories, music, cords, tuners, and other "stuff") has a padded inner compartment, so it is perfect for carrying small amps like the Acoustic Image Clarus (or the brand new Clarus SL), the EA Doubler or Micro, or the Traynor Small Block head. Of course, it's also great for carrying preamps, cables, tuners, extra strings, and all of your other random gear.

SPECIAL OFFER: Until the end of August, add it to any order totaling $250 or more, and the price of the gig bag drops to $20!
One discounted bag per order.

Trying to determine when your bass was made? Here's a convenient list of serial numbers from Kay basses and those of their successors, Engelhardt. The original Kay serial number list was originally compiled and published by Roger Stowers at his amazing Kay Bass resource site; the serial number list has now been duplicated extensively across the web, which is why I am sharing it with you here - but if you're looking for Kay information, his site is a great place to start!

INSTRUCTIONS: Each serial number on the chart is the FIRST bass made that year; if your bass comes after that number (but before the next year's first serial number on the chart) then your bass was made that year. So find the first number on the chart that is higher than the serial number on your bass - your bass was made the year before that.

Example 1: if your Kay Bass serial number is 25521, your bass was made in 1951.
Example 2: if your Engelhardt Bass serial number is 88000, your bass was made in 2005.
