If I have an acoustic guitar with pickups installed, how do I plug it into a combo jack a PreSonus FireStudio? Do I just need to run a 1/4 cable into the combo jack, or do I need to go into a DI box, then XLR into the combo jack?
the fire studio has 2 mic/ instrument inputs along with 6 mic ins. you can use the mic/ instrument inputs to plug in a guitar pick up direct..
Would this work?
Bass >>>>>> DI Box >>>>> one out to the amp (miced), one out DI to the instrument jack?
If you have an external DI box, feed the amp via a standard guitar jack lead from a "through" or "by-pass" or "parallel" output on the DI box, i.e. the raw bass pickup signal. Use an XLR-XLR cable to connect the DI box output to a microphone input on the FireStudio; don't use a DI input jack on the FireStudio in this case.
unless the acoustic guitar as a high end dual pickup systeme, a mic is a better choice.
