Has anyone swapped out the 498T for a JB? I have a Standard that is basically O.k. sounding with the 498T but looses out to my Hamer FM Special in terms of tone. I have a covered JB laying around and could change it pretty quick but I don't feel like doing it if the JB flat don't work in a SG.. Reason I'm wondering is that JB's don't have a lot of low end and can be bright which would not necessarily be a good thing with a SG. I also thought about a Custom 5 but they spec out close to a 498T (14K, alnico 5 mag etc.)
