For me, these features mattered because I wanted something that fit my space and my playing style.
Sound Quality That Worked for Me
The first thing I noticed was how important tone was, even in a small practice amp. I wanted clear sound at low volume, and I preferred an amp that didn’t distort too quickly unless I wanted that effect.
