WELL I DID BUY THE F-50 AND LOVE IT, IT IS EVERYTHING I WAS LOOKING FOR AND THEN SOME. MY QUESTION IS CAN I SIT IT ONTOP OF A 4X12 AND STILL SOUND GOOD.
You can definitely do that - best if the cab is rated at 4 or 8 ohms and plugged into the approriate jack on the back of the amp. F-50 sounds HUGE through a 4x12.
