Re: gfs pickgaurd
I would think this is more of a sideways jump than a forward one. Single coil pickups hum. Cheaper single coil pickups don't sound great, and still hum. For some (like me), no matter how good the pickups, single coil hum can get annoying, so I go for a silent option, like Stacks. I am the mind of getting a pickup set that solves your problems, and
1. solves the problem you are having &
2. sounds better than stock pickups.
A cheaper prewired pickguard might be a good solution, but my guess is that the pickups in there are about the same quality of what you already have.
