Bought both of these items and really hope it takes my fretwork to the next level... https://rectifymaster.com/index.php?option=com_content&view=article&id=130&Itemid=120 https://rectifymaster.com/index.php?option=com_content&view=article&id=118&Itemid=101 Here are the youtube links for these products, they are the only ones I could find... I also bought a fret guru leveling beam, a fret guru fret end file, and one of these to help smooth fret ends... https://www.ebay.com/itm/GeetarGizmos-THERMO-FORMED-Fret-Crowning-Dressing-File-Luthier-Guitar-Bass-USA/130977531047?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 you can buy the sanding paper belts for them cheaply from amazon in all sorts of different grits. I plan on then using the 7 in 1 fingernail files to buff out the fret ends to get them to a nice mirror shine. I also took the advice of some here and bought some of the 3M sanding sponges and a cheap set of harbor freight jewelers files to knock down sharp fret ends and take care of fret sprout. Ive had success using those things so far for fret sprout but thought I would take it to the next level with all these new tools. The LittleBones cost $25 + shipping and the BUZZ Killer cost $75 + shipping. The brass ones are even cheaper which they show on their website, but he charges more for the ICE version which he claims is more durable and the material last longer. He also has the Katana, which is very interesting... you can fret level under string tension, read up about it on his site! Too rich for me right now, but very interesting. he is from Japan so you do have to pay shipping and wait a bit to get stuff. He is also on facebook and usually responds fast there... https://www.facebook.com/rectifymaster/ Please, if you do get anything from him, please mention me from this thread (Chad Underwood). I know that stewmac came out with the z files which are pretty much a ripoff of this design, but oh well... Id rather pay $100 for all this stuff instead of only getting one z file from stew mac for the same price. Anyhow, this guy was very nice and answered all my questions no matter how many I had for him, I dont mind one bit helping spread the word about him here... pass this along if anyone you know are into doing fretwork yourself.
