Ok my amp is basically worthless... and so ive decided im gonna get the MM jazz, most likely... and if im gonna drop a grand on a bass I better have a good amp for it, or whats the point eh? so, im thinkin of spending maybe $500 on a new amp, do u think that would be sufficient? could I spend less than that even? or should I spend more than $500? and I know that price isnt everything... do u have any specific suggestions?
