a few months ago while vacationing in hawaii, I've tried out an Ibanez gsr205sm through a fender rumble v3 100 and it sounded pretty killer. I don't know if it's just me or does the gsr205sm seem to have a more punchier sound than the Ibanez sr305. I like the sr305. especially since I own one. it's just that the gsr205sm has an incredibly punchy sound for a cheap bass. and the sr305 has a more smoother, but versatile sound. Whatever the case, I still declare that Ibanez soundgear basses is one of the best active basses I've played along with schecter stiletto basses.
