I thought u needed a DI box to plug in guitars? If u read the manual carefully (and on some forums) you'll see that the line inputs require a separate DI box....pretty annoying. Or do u have a DI and still have that problem?
I like the mic pres and DAC. The DAC really does sound great for this price range....I marvel even at YouTube video's audio sometimes lol!
But I'm starting the hate the drivers, latency, and even the DSP mixer thing. I might revert back to my EMU 1212m and go SPDF I/O into the Tascam, to get best of both worlds.
