A friend of mine is selling his Roland almost new, but my problem is a few months ago I’ve bought an EBS 30 watts, but it has no effects.The Roland has a lot of effects, so I’m asking if I should buy it and kept the EBS and the Roland.I’ve been playing bass for the last three months, I know playing guitar but I’ m new to bass playing.Another hypotheses is keeping the EBS and next year buy a better amp, with 60 watts for example.
