I have tried several different brands & style pickups in my SG & I just cant seem to find the right sound. I play blues & classic rock. I have Rio Grandes BBQ's in the guitar now & they have a muddy tone. I'm thinking about a Crawler set, but I dont want to spend a lot of money and find out they have a muddy tone or a weak sound. Please, somebody, let me know how they stand up to other brands. Thanks.
