A 'Racing' stripe characterized by a single wide stripe with 2 parallel thinner lines. The stripe is demonstrated in Caddy Pink on the Squire Paranormal Super-Sonic, and again in Supernova Champagne on a Yamaha Revstar. The default length should be suitable for most applications, but if you want to install it on a 335-style (or a Revstar), let us know and we'll make one that's a bit longer at no extra charge.
This comes straight from the vintage 'competition' series guitars and basses of the late 60's and early 70's. There are still reissues of instruments that bear the stripe - you can grab one of those, or snatch one of these.
