I scored an Ibanez SB7 from eBay for about 40 bucks and a week later, it stopped working. I play a G&L L-2000 through an ampeg svp-cl and had the pedal placed between the bass and the pre-amp. Anyone know what is wrong with it and how I can fix it? It was working fine when I got it but now it has a very VERY low output volume though I can hear it when I crank up my amp. ideas? I loved this little thing other than that.
