Ultimately, beauty is in the ear of the listener so i hope not to offend anyone so please take this discussion in a light frame of mind...
What records can you name that could have benefitted (in your opinion) from a better guitar-tone rather than a sound akin to running your finger-nails down a blackboard. (Kids- ask the elders if you don't know what a blackboard is)
i'll start the list with a couple of great songs with great solos but what I consider to be a guitar-tone I'd do my best to avoid as a player:
- the commodores "easy" guitar solo
- the carpenters "goodbye to love" guitar solo
On the other hand, does anyone like to use the kind of tone these solos employ?
