Price seems to be the biggest obstacle with the NutBuster. At first I scoffed at the price and gimmicky popped in my head. Even some of the post say things like "if you need this than you need a new guitar". When you have a gig the last thing you want to do is tune between every song. I've got a Gibson Paul and a Fender Stratocaster. The tuning sucks on both. I use both. The Les Paul tuning is tolerable. The Stratocaster is unacceptable. The Stratocaster I've had the longest and I've invested the most.
I had a friend that I worked with that needed some cash and asked me if I wanted to his Stratocaster for $250. The next day he brought it in and showed it to me. I took one look and asked him if he wanted large or small bills. As it turns out, the Stratocaster is a 2004 Limited Edition Lite Ash Stratocaster made in Korea. It came stock with a birdseye maple neck and fretboard, ash body, Seymour Duncan single coil pickups and the American Elite bridge. Like most Stratocaster guitars, they have to be rebuilt before they're playable.
First thing to go was the nut and tuners. I installed a maple shim to correct the neck angle. Then, Fender locking turners and a roller nut. I'm really not a fan of 60 cycle hum so a Sigler 920D loaded pickguard with Seymour Duncan's Everything Axe. Not only can I split coils, I can have the bridge and finger board together. And last but not least, Graphtek saddles and string trees. Even tried putting graphite on all the contact points. The guitar plays and sounds great...when it's in tune.
So what's next? A Floyd Rose? I do miss the Floyd Rose I had on a Hamer years ago with fine tuners. That would be a major modification and cost more than $175. As for gimmicky, the roller nut is gimmicky. The design with string trees has always been a problem for Fender. The engineering behind the NutBuster is valid. The design goes right to the source of the problem. For what I have invested in the Stratocaster I could break even if I sold it but I wouldn't be the same. I'm willing to roll the dice one more time. If this "NutBuster" does what they say it does than it will be worth it. Would you put a $15 filter in front of a $1000 lens. Quality comes at a price.
