Hey, i'm looking for an upgrade on my Ashdown Combo in the form of a bass head and cabinet, I'm a 17 year old student who wants to start gigging with my band when we get gigs. As I am a student, money is sort of an issue. (I'm currently searching for a job and have interviews lined up) I want something of a workhorse that doesn't leave me in debt forever. I will be looking for pre-owned and used stuff mainly as there is a chance to get a better deal, but what in your opinion would be a good place to start in terms of brand and model of a head and cab? I could sell my combo as it's in perfect condition still, and also I have an unused bc rich that could be flogged if need be. Any similar personal experiences?
