I'm always tinkering with my guitars, especially my Stratocasters. I have a LOT of Strats - some American, some Mexican, some Japanese, and a lot a mix of all bits from all over. I call these my mutts (most call them Partscasters). My mutts are my favorites. When I was just starting out with guitar back in the 80s, I was happy just to get my hands on anything, but, as I grew into the instrument, I started changing things - new pickups here, new tuners there, shave down the neck, etc. It's a fun hobby, especially now that I'm playing more for myself and not really in front of audiences, so I'm less particular about "brand names" and stuff I used to think mattered. Don't get me wrong; I still demand QUALITY. I just don't particularly care whose name is on it is all.Lately I've been using a lot of Chinese-made stuff. I mean, it's pretty much the same stuff you're going to find on 80% of the guitars out there as most of the big manufacturers of guitar parts moved their operations overseas years ago, but, while they save money on labor, the savings are definitely not passed on to we musicians. Those big name companies still make a limited amount of their higher end product in the US or Europe, but I've discovered that there are very few examples where the difference in quality justifies the difference in price.I mainly use parts from Japan, like Gotoh, and one of the better known Chinese brands, Guyker, but lately I've been grabbing stuff from Musiclily as they (much like Guyker) have become something of a big player on the parts scene and have really stepped up their game.This set of Pro locking tuners was sourced for a new build I'm doing with a relic'd Strat body and a Mexican Fender neck, along with a hodge podge of other bits and pieces I had laying around. The Musiclily Pros arrived in a week or so, and they immediately impressed with a nice mix of retro aesthetics and modern functionality with those nice amber Keystone tuning keys and the four screw mount base that fits the old school vibe. The locking system on these is dead simple and effective - a long pin runs up the shaft and, with a twist of the furled wheel on the back of the tuner, pins the string in place. It makes stringing a breeze, and I actually much prefer these over the mechanism Fender uses in their locking tuners. The Musiclily's are also very well constructed, made of a combination of solid brass and zinc, and feature a nice subdued chrome finish. They also are FREE of any huge logos or "flair", which is one of the reasons I stopped buying Guyker stuff as they got more popular (and more expensive). I'm not anti-corporate or anything, but sometimes I just want my stuff to look a certain way, and when you've got all sorts of branding all over it it sort of kills the vibe.The tuners work very well. A good string stretch and tune-up, and you're ready to roll. They're a bit stiff, which can be kind of a pain with such a fine tuning ratio as 18:1 (tiny adjustments can be a bit of a chore), but a little loosening of the screws on the heads mostly takes care of that.Whether you are a constant tinkerer like me or someone who wants to upgrade lesser quality tuners on their stock guitar, you really can't go wrong with Musiclily stuff.
