Well, used mk4/41/21 are around $1,300-1,600 sometimes less. And the REAL KCY is $880.00. TinyBox is around $300 I guess
I just ran mk21>KCY>LB>M10 StageLip NOS last nite and mixed with the vocals of the SBD, it sounds KILLER> mk21s picked up all the instruments and the SBD picked up vocals and harmonica. I'll post a few samples tomorrow probably
