This unit is certainly functional for some tape effects. saturation, or lofi. Input 1 seamed to not record for me...but inputs 2-4 recoreded just fine. Outputs work great. the counter reset button is missing, but I was able to reset just fine with a pen. Comes with original power supply and a high bias tape with barely 3min of sampling nonsense on it. Would be perfect for some lofi mixdowns or effects. I did not test with batteries.
