I too, am a fan of the K4, which I purchased on Fran's recommendation. The unit had a small electronic problem which resulted from poor packaging for shipping (this is a common complaint of Traynor) but was easily repaired. When properly set up (channel 1) it makes my Nord C1 organ scream and more than enough volume to compete with acoustic drums and (jazz) guitar in a medium sized club setting. Although there IS a mic imput, I don't use it for vocals (seperate system). Modules, such as a Sonicell, sound good with it as well, with good seperation from the organ channel. A little klunky to carry but a great choice if you don't mind spending a few extra bucks.

PS: Dave, really liked the band video with the "B". Good to see someone playing pedals for a change (I use the Roland PK7a with the Nord which works very well).
