Are these basses any good because I am wanting to buy one off of craigslist for 150, its an acoustic(model number JBEAB3600). bass
I would pass it up. Most acoustics are not that good.
The good Captain is right. To even get near decent on acoustic basses the budget needs to be much higher. Cheap acoustic basses sound just like that: cheap.
i know nothing about acoustic basses, so i wont pretend to. anarkee and the captain dont like the idea of an acoustic bass for $150, so you probably shouldnt go for it, but i have a 5 string JB Player stingray knockoff and it was a great value for the price ($250). thats my two cents.
