Did you connect iRig headphones 1/4" output into the amp aux input, or connected 1/8" cord to the guitar input? latter will of course sound different.
If connected to the aux in on the amplifier and if amplifier/speaker setup is decently linear - you should not get too much difference from what you hear in your headphones.
I think you’re right. That was my mistake. I was playing around with it the other night. While I was jamming with some backing tracks I noticed that the tracks had a reverb on them from the amp. So I thought maybe I’ll feed the backing track into the aux input to see if it’s still there. Voila! No reverb and actually no control over the tracks at all from the amp. It was being feed after the preamp. Ding-ding! A light bulb went off in my head. So I feed my AmpliTube input into the aux of the amp and it was 100% improved.
I think I might be able to work with the tones and get a good result. However, I’m still curious about the Iloud. Would it out perform my 25 watt frontman amp in a small jam setting with other band members? And would an upgrade to the HD model irig be worth it?
