Marshall JVM410H Half Stack. This is a versatile all-tube guitar amp that lets you switch between multiple Marshall circuits, from the old JTM45 to modern high-gain. It's also the amplifier that GuitarSite.com chose as the top amp for 2016.
1978 Fender Bassman 10. My first amp was one of these. Got it when I was 17, for $150! This isn't mine, but it's even the same year. Mine is no more. It was a great amp, but used to fall over on its face b/c the casters were not up to the job. Sounded nice & punchy, big & warm. Broke up a little too high on the volume knob to ever get tube distortion at home, but when you COULD open it up, WOW. It sang.
