Tube amps use vacuum tubes for a warm, touch-sensitive sound that breaks up naturally, but they’re heavy and need maintenance. Solid-state amps use transistors and are cheap, light and reliable. Modeling amps use digital processing to imitate many amps and effects, making them the most versatile choice for most players.
The tube vs solid state amp debate is older than most guitarists reading this, and modeling has turned it into a three-way choice. Our guitar amp modeling guide explains how digital modeling works. This guide compares all three types so you can decide what to buy.
Below you’ll find a clear tube vs solid state amp comparison, where modeling fits, and six proven picks across the three types. If you’re leaning digital, also see the best amp modeler pedals, and if you’re comparing capture technology, read NAM vs ToneX vs Quad Cortex.
