I have been looking for some video comparing these two instruments on the tube, with no success....in the end I bought both of them along with time due to specific musical needs....it seems like I am not the only one who wonders what's the sonic difference between the ll6 and the ll16....so I made a review about it...even if it's an old thread I thought I would share...down here the link of the vid...hope you find it useful
