Hello everyone: I've been playing electric bass for quite a few years, but have pretty much remained in the realm of heavy music throughout that time due to other band member interests. In the last couple of years, I have been listening to a lot of progressive music, and feel I have finally found what I'm looking for. In the last 6 months or so, I've been getting into jazz, and jazz fusion quite a bit, and it's really opened my eyes. I have lately been thinking of purchasing a double bass, but am not sure if it is COMPLETELY different than the electric bass. My question is... For those of you that also play the electric bass, how is the transition to double bass? Would I be starting from scratch on a completely different instrument? I have no experience with an electric fretless, and am a little frightened of experiencing this without at least some kind of fret markers. Perhaps it's just wishful thinking on my part, but I am just fishing for ideas now. Oh, and I apologize if this has been asked, I tried a search, but had no idea what to use for keywords. Thanks for any input.
