Does anyone have any experience with the Instrument/Hi-Z input of a Mackie Onyx mixer? I'm not sure if it's good enough. My current signal flow is guitar into Mackie Onyx HI-Z input, the output of the Onyx is then fed into the direct inputs of a Pro Tools 003 rack. The impudence of the Onyx input is 1M ohm and the DI on the 003 is >300k. I use active EMG pickups. I was thinking of getting a Radial J48 but it is pretty expensive, I'm happy to spend the money if it gives me the best results. Many Thanks.
