Because I was big fan of Robben Ford, I stopped using reverb and just went for a short delay (snapback, or thereabouts) because I read somewhere that he didn't use reverb as it could muddy things up too much. Also being a Brian Setzer fan, this all sounded to be what I wanted. I bought a Line6 DL4 and thoroughly happy with that. I've long since parted company with everything I had back then, as I was concentrating on playing bass. Fast forward to now and I'll still choose short delay over reverb (although both together can be OK, if used sparingly) and, to sate my echo needs, I bought a Behringer analog delay, works fine, albeit in a plastic case. All that said, if I were gigging regularly, I'd probably look at a Boss RE-2 as that would do everything I want, what with emulating the classic Space Echo (more Setzer influence).
