I'm curious if anyone has tried using the Amplifire through some typs of tube power amp then into a mixer and/or soundboard for live use? I'm still tweaking and gigging my A3. I've played tube amps all my life (currently use a PWE Event Horizon III or a Suhr PT100se) so I'm missing the warmth and tone with the A3. To me that is the only element missing from the A3. I would love for the A3 to have some kind of tube connection. So if anybody knows of a way of running an Amplifire into a tube powered source then out to a soundboard or mixer, PLEASE let me know! Thanks.
