I haven't had one of those but I used to own a Woody with the adjustable hex screws, and it was low output and hums. So does my Duncan Performer Maverick. However I tried running the Maverick into my POD XT and messing with the acoustic models and noise gate\compressor and got a useable tone with little hum. I think they use less winds\lower gauge wire for more clarity, but that and being farther from the strings than it probably should be makes for low output and more noticeable hum. Not to mention there's no string ground on acoustics.
Right now I'm using a Low Impedance humbucker I wound and running that through a mic preamp.
