I've read lots of pros/cons regarding big guitar necks and tone, and now have some real experience with it. I replaced the medium size neck on my tele with a Warmoth compound fatback over the weekend. The difference is quite stunning. It is a full 1" thick C shape the entire length which turned out to be a bit much, so I hand sanded the shoulders down a small amount. The wood removal was minimal but the feel difference is considerably better. It's also has a rosewood fretboard so that must be contributing to the change in sound. It seems to simply have 'more'. Sustain, body, improved tone, even a slight volume increase when compared to my strat with the same neck carve as the original tele neck. Anyone else finding positive/negative results upgrading or changing your bolt on?
