Hey, I'm thinking of getting a new bass. I have an cheap, old Fernandes and I'm thinking of upgrading. I'm trying to shoot for under $600 but under $400 would be preferred. I know I want at least 5 strings. Thing is I don't know anything when it comes to buying basses (the first one was a present). I play a good variety of music, metal through folk rock and funk and some jazz. I like to slap and pop a lot as well as tap. I have an Ampeg amp and no bass effects. I'm thinking Ibanez or ESP so far, but can easily be swayed. So 1) What are some things I should look for when picking out a bass? When I go to the store, what are some things I should definitely take a look at and test out sound-wise, action-wise, what kind of bridge should I look for (and what types are there?) etc.? 2) Is there a noticeable, important difference between 5 and 6 strings? How much extra cost is that usually? 3) Would there be any point of getting a fretless for this style of music or is it just unnecessary extra price? How much extra price?
