96% of the time that I'm play guitar I'm practicing with headphones. Currently I'm using an Orange Crush 20-RT, which is a decent practice amp but I'm not in love with the dirty channel on it. I would love to have more options as far as amp tones goes, particularly something that sounds good when playing at low headphone volumes. My requirements are: - Must be able to connect headphones. - Must be able to connect an aux-in somehow. - Not too "fiddly" - I've looked at some of the zoom-type multi effects pedals, and they are cool but I would rather have something with less options but easier to quickly switch (eg. physical buttons over screens, no audio interface + computer, etc). I've looked at amp modelling pedals like the Strymon Iridium and the Walrus ACS1, and these seem basically ideal except that they have no aux-in. I'm often practicing over backing tracks, metronome clicks, etc so I need an aux-in. I'm also wondering if one of those little 1 watt tube amps might be good for getting a decent low-volume tone over headphones. Are there any other options I'm missing? Any feedback is appreciated, I'm pretty much a novice at all this stuff so may not even be thinking about this the right way. Thanks!
