I have a bunch of guitar pedals (stompboxes) that are sitting idle. I'd like to run a mono track of music from my computer through these pedals and record it back into the computer again. The audio might be anything from drums to a synth. Of course I'd like the quality of the audio to be as high as possible.
I have a Presonus Firebox which I believe I could use to do this. Here are its specs:
My understanding is that the preamp instrument inputs will be suitable but that I could use a DI box and input to the mic inputs instead? Is this correct? What will the difference in quality be do you think?
What about the line inputs? Can I connect these directly to the pedal chain or is the output impedance too high?
The outputs from the firebox are balanced TRS and have a 51 Ohm output impedance.
