I have purchased 2 SBS guitars. The first was a "reliced" Jazzmaster/Mustang style and the second was similar to the pic at the top of this thread, but in metallic purple - oh, and no relic stuff.
The "relic" finish is pretty much crap. You can tell they just bumped against a grinder wheel a couple times. Way too uniform for a genuine relic look.
I can't say I agree with the description of the roasted necks. When I've removed the tuners, I can clearly see through the hole and the wood is the exact same color all the way through. Tone King also did a drill test and the shavings were the same shade as the top of the wood. If it's not real roasted maple, I don't much care. Because....
I have over 20 other guitars. Most of them have been customized in some way. My life long favorite has been a Mexican Strat that the only original piece on the guitar now is the body. That guitar and I bonded better than any other I have ever owned or played. That was until I got my first SBS. The 20-inch radius sounded insane to me. I typically have a 9-16 compound radius neck and thought that was the end all for my hands. Nope, the 20 blew that out of the water. It just fits my hand so much better. Then came the pickups. I have been a massive Duncan fan for decades. These SBS pickups have more low mid growl than any other pickup I've used. There's just some serious b*lls to the tone. The tapped coil isn't as good as a Duncan, but it's good enough for the few times I need it. The pre-wired treble bleed circuit saved me a headache, too. I tend to put those on every guitar I have.
For the money, I haven't found a better guitar. No, it's not top of the line, but for me, SBS guitars have the feel and tone I want. I would highly recommend them to anyone.
For the record, the second SBS I purchased was from their "Custom" line, which is the cheapest of the 3. No relic crap and they swap out the Alnico pickups with ceramic as well as using a Floyd "licensed" tremolo instead of the genuine Floyds on their other 2 lines. I happened to have a Schaller Lockmeister on hand, so I swapped out the licensed Floyd for the Schaller. Personally, I really like the ceramic pickups. The first guitar came with alnicos and I actually swapped those out for the ceramic versions. Smoother high end to my ears.
In the end, we all like what we like. I wish these were available in stores so others could try before they buy. But then again, I am the only guitarist in my area that has one (two!), and that's ok by me as well.
