What do you guys think of the grx20...

my friend just bought one. I have not played it..

he wants to upgrade the pick ups... he knows close to nothing about guitar...
do you even think thats a good idea...?!

A pickup upgrade probably wouldn't hurt it, but a lot of the tonal change will depend on the amp.

HOWEVER, the biggest issue here is the fact that it's a $150 guitar. If he wants to change both pickups, he'll probably end up paying at least that same amount. He would have been better off investing in a better guitar to begin with.

EDIT:

he's playing on an amp that I GOT FOR FREE and SOLD to HIM for $20!!

yes it sucks.....

PLUS the fact that his guitar has not been set up
