My expectations were perhaps unrealistic. Yes it has good tone, and yes it's plug and play. However, it's still a digital modeler, and you still need to dial in your tones a little, as you would with any "real" amp. At first I was a bit disappointed. Going through headphones - akg, audio Technica, Grado. But I think I was a victim of the ridiculous hype. I've been using my modded 68 CPR with a brake light attenuator and some bedroom sound treatment (very mild), and it's been really good for jamming out, with my pedal board, during the work day when the wife and kid are gone - we're in a townhouse. In the evening, I get hints from my wife that it's a bit irritating at 3 on the cpr, attenuated down 11 db (full). On 2, the tone becomes "just ok" and it's still only quite enough for pre-bedtime. So needed a solution, as most of us do. Tone was the priority, so went this direction. My desktop monitors are crap - too bass heavy, so have a decent pair of JBL on the way. Lucky to have a great pair of cans my brother gave me - Grado ps1000. These things are worth more than most of my guitars. That helped boost up my expectations too I suppose. Anyhow, today I just had a fantastic experience with the Iridium. A/b'd it with the Princeton at 3, then at 2. Different obviously, and the cpr edges it out when on 3 (attenuated). But compared with Princeton on 2 (also attenuated), the Iridium through cans gave me an overall more inspiring noodle. I think a real guitar speaker can only tolerate so little volume. I think it's important to run a little reverb - the room knob is more to emulate an amp in a room, but it's still a bit "dry." You also need to dial in your tones.. it's not automatically glorious tonal nirvana. And yeah, the cans (and hopefully monitor arriving soon) make a difference. You might need to experiment. My akgs are more expensive than my ATs but sound way worse. The grados kill, but they are $1600 (I think, didn't buy them). Another annoyance is connecting. No XLR or balanced trs out. I was told I could try short instrument cable to the monitors and it should be ok, but monitors want balanced, due to possible noise issues. So you need a stereo DI to do things properly.. another $300... In the end, if you want to invest in a low volume set up which can include your pedal board, and have the ability to go straight to FOH live, this is a worthy endeavor imo. The tones and dynamics are there.
