Ok, so after playing four strings for thirty plus years i just decided to get a fiver and see how i like it. Found a great deal on a G@L L2500 tribby here on TB. It's got me to wondering if my various bass rigs can even handle such low frequency's and wether or not I'll need to upgrade. Currently my main amp is a mid seventies ampeg V4b paired with either an old peavey 2x15 with black widow's or an ampeg fridge. As a alternative I also have and use a GK 800rb. Plus i have a vintage svt that only gets brought out once or twice a year. Ive had prior experince with g@l basses tending to drive the ampeg heads a little hard so my first inclination is to stick with the gk but it's older and maybe not suited to a five string. I'm sure the peavey probably does'nt have the best low end response either. So what would you upgrade first if anything? Any advise is much appreciated.
