Maybe you don't know it (yet) but on vibrato equipped guitar, the metal block below where the strings attached has a very important role in your tone. I heard about the FU Tone product through the years and I thought it would be interesting to have the guy behind the product to talk about it. So here I am presenting you with an interview with Adam Reiver from FU Tone.
Here's below the block Adam sent me to try on my Ernie Ball Music Man EVH model. I will try it and report here on the website my findings.
