I am in need of a new amp. I have to sell my Ibanez SR885 bass and my Kustom KBA100. Any thoughts on how much I would get out of them? I want something that will get louder and have more overhead than my combo. I usually have my combo maxed out. What would a reasonable price be for a Kustom Tuck and Roll amp head and cabinet? I've been looking on Ebay. Any other suggestions on cheap amps that will give me the volume I need but still be able to lug around and that I'd actually be able to buy?
