I found number of negative reviews / articles about the GraphTech bridge saddles and its negative influence on original sound of Fender Strat. I did not have a chance to touch it on a real guitar. So I was not sure until the latest, until I switched the guitar on to an amplifier. The result is amazing! Tone / sound is perfect, it gives classic Strat's sound.
GraphTech PG-8000-OC installed on Fender Strat with Vintage tremolo bridge (year 2005/2006).
Pros: quality of product, quality of sound, better tuning, nice sustain.
Cons: Description of product is lacking information, price.
