Hi all, I have an old Firewire Solo that I've been using mainly for pre-demos and youtube videos, however, in a few weeks I'm tracking DI guitars for an EP and I would like to achieve the best quality possible in such DIs. I read some days ago that the Hi-Z input (instrument input) in the Firewire Solo is not very good and some people recommend the use of DI boxes using the mic input instead. Do you think a DI box is worth buying? Would it make a big difference in the quality of the DIs? Thanks for your help.
