Was a little bit sceptic but this accessory really ads a little bit of oomph to the guitar's tone. It enhances the lows and ads a little bit of stability to the guitar's timbre and tone. Did some A/B tests to figure that out. So if you have a guitar that tends to sound dry and unfocused, then you found a nice solution to it in the Fender FatFinger. Sounds even more obvious when recorded. Definitely recommend buying one, think of it as a capo or slider in your accessory kit that is good when you need to enhance the tone of the guitar. Cheers!
