I looked at Roland Micro, Marshal, and the venerable Pignose.
I have a practice amp but want this to play electric guitar without bothering the neighbors. Ideally it would be extremely portable. Amazon's list looks so cheesy: https://www.amazon.com/s/ref=nb_sb_noss_1/146-1273913-5675546?url=search-alias%3Daps&field-keywords=tiny+guitar+amp
Other than features, any recommendations?
I have to own at least a half dozen of them still, and have traded away or sold even more. They're great and not even all that expensive.
Considering how infrequently I recommend specific brands, consider this a recommendation. Any model, literally. Your expectations will be met - assuming you're having real expectations. No, you're not going to get massive overdrive like Marshall stacks with a Marshall head provide with the flip of a switch, but you can get pedals and have fun. You're not going to get screaming volumes, nor will you get massive feedback. So, scratch those off the list.
You can get remarkably clean, crisp, and surprisingly rich tones from them - and some warmth in bass, which surprises many people. They do a great job.
Can I change the world?
Sorry for the delay. Pignose, any model. Hands down winner for serviceability, longevity, quality, and tone for size.
