Right now I have a DW 7000, which is working fine for me but I'm looking at the 5000 series. The reason being I've heard they're better in that they're smoother and have more adjustments. My 7000 is quick but it's not as smooth as I'd like it to be. My question is what is the difference between the Turbo and Accelerator models? They're both the same price on musiciansfriend but the Turbo has a higher customer rating. I've fiddled with them at Guitar Center but never played them behind a kit. Can anyone share their experience with them?
