Hi guys, I got a Bag End Q10BX-D thur a trade at a local music store along with a Thunderfunk head. The head sounds fantastic but the cab has me desiring more highs. If anymore is familiar with the Thunderfunk heads I have the high trim turned all the way up and the high frequency all the way up, and it still seems like the his aren't there like they should be. The can gets very deep and I've tried to trim back the bass but the hiss still aren't giving me that fulfill range sound i'm looking for.... I'm using a Ken Smith bass. Any suggestions?
