Regarding size; the 336 is often described as a scaled down 335...close to the size of an LP. The shape of the two is basically the same. The 335 is laminate, the 336 solid and the 336 sound is said to be between a LP and a 335.

I don't have enough experience or a well enough developed ear to comment on the sound comparison but I can say I'm very, very happy with my 336.

On the other hand, Johnny Winter noodled with mine back stage and declared it, "...a real sonofabitch." He meant that in a good way. ;)
