If you have track#1 - guitar input (dry guitar, directly from your DI box or whatever. The FW1884 has a "guitar input" track) - I'll enable for record and instead of sending the sound to the monitor/master I send it to output #3.
Output #3 is connected to the guitar input of the HD500.
And I'll then connect the output of the HD500 to track #2 and #3 (for stereo)
If I want the sound of the HD500 when playing, I'll have to enable input monitoring for track #2 and #3 I think? Or I can use headphones.... :)
Anyone have a clue if this would work, or will it only be a mess?
Someone at the Line6 forum was sceptic because of impedance, but I can not see how the impedance would be a problem? Would it be for the output from FW1884 in to HD500?
