Hi there,

I have a Fender Strat with lace-sensor pickups (Red, Silver, Blue) which are
the original ones not the newer ones. As I understand it, lace-sensor have a
higher output. For now I'm using an Griffin iMic connected to the USB input
on my PowerBook. 

Does anybody know for sure if the output of these pickups is line level or
mic level? The iMic give a choice to select between line or mic.

I think they are line-level but I don't know for sure. Also, what
measurement of output qualifies as line level?

Thanks, 

Robert
