First of all i apologise for the for the dumb title, my brain has not yet booted completely to come up with a more meaningful...title Here's the situation, right now i am using an AXE FX II to record guitars and bass. The AXE FX II is directly connected to a RME ADI 2 PRO USB interface/DAC. I would like to simplyfy my setup as i am using the Diezel VH4 Sim in the AXE FX II 99% of the time. I am thinking to either try out some of the latest modeler Software (Helix Native) or to buy a few preamp pedals (Diezel VH 4 pedal V2 for guitar and Darkglass Mictotubes B7K for bass) Do i need a DI Box in both cases to connect the guitar/bass to the RME interface/DAC? I also have a fairly nice Great River Preamp that has a HI-Z input. I know that the HI-Z input is designed to accept guitar/bass signals but i am not sure if there is a significant difference to a high quality DI BOX. Any ideas?
