I have had 1 of these Groove Tube Fat Fingers before. I put it on my main guitar for years. It does add sustain. It does it by transferring the resonance back into the instrument by feeding back the resonant energy back in to the guitar through the headstock. It is only a slight difference, you will feel it if it is applied properly to the head stock. I bought 2 more recently, noticed right away on my Heritage guitar had increased sustain. I plan to get more for the rest of my guitars. Groove Tubes makes great products. Fender now owns this. So, they are called Fender Fat Fingers. They work on various instruments: bass, acoustic, anything it can clamp on to the headstock. It simply increases the sustain as it says. There is felt on the bottom and top of the clamp shape to not damage your instrument. Read full review

I placed it right behind the nut on my Stratocaster. I can hear a difference, not too much, but it's there. Every little bit helps! Make sure you have it nice and tight!

Read so many reviews before making this purchase GOOD / BAD so here's how it went for myself... I felt the head stock while playing the guitar then added the Fat Finger, ( Before ) lots of vibration in the head stock ( After ) could feel no vibration in the head stock period!! I have and play 11 different Guitars of different brands and found the same effect on all. NO Vibration after adding the Fat Finger Did it change the sound? amazingly...YES. Will you have the same experience? I can only speak for myself ...It worked, I will buy a second one to use on my DBL neck SG I'm that sure of it working. again this is only my opinion.

I put one on the very end of the neck on my Jackson USA guitars. Instant additional sustain. You can actually feel the neck vibrating. The vibration is subtle...the sustain is very real. I was skeptical. Not anymore. I also mounted my Snark tuners to them and they work better now because of the extra sustain too. Accurate for a longer duration before the signal fades. Makes tuning easy.

I got this to try out. I did not try every possibility and considered trying it on an acoustic or mandolin. Tried it with a strat I didn't notice any difference.
