Buzz--
I own a 3120 and I've played a 2020 on a few occassions, so I can provide about $0.01.
The 2020's piezos are really cool--they sound really great combined with the
mahogany body. Unfortunately, the
Ibanez pickups are really disappointing. They could be easily be replaced, but I'm usually not looking to spend $150 additional on new pickups when I buy a guitar that costs that much.
Personally, I like the look of the 3120--mine has a really sweet flamed maple top. I prefer the visual 'wow' factor becuase I can't think of many cases where I'd put the piezos to good use. (but that's just me)
