I'm selling off a SIMA SFX-10. It's a fun little mixer I was debating on circuit bending for way too long and just don't have the time to dedicate to it. Issues - Missing 1 slider -Joystick is snapped off but still functions as it should -on the B effects bus: the mosiac button takes a few clicks to get it going -on the B inputes: the 2/4 buttons need a few extra clicks to activate Other than those issues it works great! I always tinkered with it as a feedback machine. $150 cash only Sima's Sima SFX-10 Digital Video Effects Mixer features digital signal processing to maintain the integrity of video signals.
