First let me advice you: I don't know ****. Ok, I have this warwick corvette standard, and I'm very happy with it. I like the shape, feeling and playability of it. But I would like some more punch and tone control. So I walked down too the local music store, and said I considered active pickups. He then told me that if I was happy with my current sound,(wich I partly am) I should rather buy an onboard preamp. What's the difference here? He also adviced me EMG pickups if I was going Active. Currently I have the standard mec pickups. Thanks.
