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?
I had one that my grandpa gave me. It was a small amp built into a strap.
Not the greatest sound quality and I ended up blowing it out one day. But that might be worthwhile to look into.
I kind of want a decent quality because I'm going to use it most of the time, and I'd like to use effects like on a regular amp.
Not at all. It was a big bully thing from like 15 years ago.
You could look into a micro cube. Had one at my parents place. A half dozen effects and not too loud.
Sorry for the delay. Pignose, any model. Hands down winner for serviceability, longevity, quality, and tone for size.
