This is a single channel maxmizer that works great. Has a very slight noise on the low contour knob when adjusting( may be able to clean.) Is dead quiet when set. Has some scratches but is overall good shape. I feel that I really don't need it since I got my Sansamp. Asking $40.00 plus shipping of your choice. Behringer Ultra DI active direct box. Used a couple of times works great. In new condition with box and manual $20.00 plus shipping. My digital camera batteries are dead. Will post pics if anyone shows interest.
