I have an Ibanez RG1570L that is my main guitar these days. It is an odd Ibanez model that was made in Japan pre J-craft. I'm not even sure what year it is. I got it in mint condition for $300.00 on consignment at a local shop a few years ago.
I emailed KGC about getting a block for the tremolo. It is lo pro trs-II
I was sent a block that wound up not correctly fitting the tremolo. two screw holes didn't line up and I lost whammy functionality as the bar threads directly into the block.
It turns out that there are actually two types of lo pro trs-II
tremolos, one that everyone hates which is made in Korea and the rarer Japanese made model that I have.
I emailed Sandy at KGC to tell him the block he sent didn't fit correctly. He was very helpful and willing to do anything to make it right for me. I decided to leave the ill fitting block inside my guitar so that I could send him the original to work from. KGC has excellent and friendly customer service.
He crafted me a custom block and sent it to me along with my original free of charge. He didn't even ask that I return the original.
I am really blown away by how awesome the block is that he made for me. Its really beautiful and fits perfectly in the guitar. It weights what seems like ten times the weight of the original. Mine was made to make contact with the guitar body which prevents pulling up on the bar but increases sustain and makes string changing a breeze.
All of the tonal claims from switching the block are true. I now have a better, fuller sounding guitar with more sustain. totally worth it. no snake oil here.
I will continue to use KGC for any tremolo I ever re-block, though I may get into the habit of just sending them the originals from now on for "odd" blocks.
you can't go wrong with KGC, they are a class act and I would recommend them to anyone, bar none. there is no comparison to thier competitors blocks.
Here are some pics next to the original.
note: there is a brass plate that screws onto the block to hold the springs in securely that is not pictured.
