It appears Becky, Bill's wife has stated "we just completed a short run of 7 string L-500's due to popular demand, and they're ready to ship!" A 7 string version of the L-500XL for the bridge and the L-500R for the neck would be interesting to hear for a 7 string. Who is going to be the 1st? Cannont be me, no longer have a 7 string.
