Agreed, there are guitars that almost got a way because of not trying this, and glad we did. Something wasnt translating through the neck to the nut to the bridge etc. The grovers fixed that problemSo I installed some Grovers on my ol’ beater of a Les Paul and I have to say the tonal improvement with regard to response, sustain and note to note balance across the fretboard is not subtle. The guitar as a whole feels more alive and vibrant.
I know there is a simplistic view that added weight at the end of the headstock deadens the response but this is completely contrary to basic physics. Even acoustic guitar makers know that proper bracing is crucial to enhancing and tuning tonal response.
Prior to the Grovers, The guitar was tonally a bit “unfocused”. The lighter kluson tuners allowed the resonances to either cancel out or dissipate creating a somewhat muddled response plugged in despite the guitar being acoustically quite loud. The Grovers have not lessened the resonances as the guitar still rings out loudly acoustically. However that muddledness when plugged in is gone. Now the guitar has greater definition and punch with plenty of sweet overtones and harmonics that a great Les Paul is able to deliver.
I do think to Grover or not to Grover maybe guitar dependent. Some guitars have a compact and very strong fundamental tone that would be better served with klusons. But acoustically loud Les Pauls especially those that seem to have a tonal response that a little more prominent in the lower mids might very well benefit from them.
I also like the looks, has that old school rock n roll vibe
