I played with both the Ibanez gsr 200 and 100. For once i can't believe i liked the cheeper one. the 200 was a p/j bass which sounded more like a country bass. The 100 was a p bass and had a low rock tone which is what i want. Know for my amp i was looking at the SWR La 15 100w. But i am pretty far away from a dealer that would let me try it out. So with the gsr 100 guitar will the la 15 be a good amp. I play alot of hard rock and was wondering if the amp can handle the low end at pretty high volume without sounding bad. I don't really have any idea how loud it will be. Any help, maybe someone has heard this amp before.
