The Mesa express is a tub amp that can run at 5w or 50watts. It comes with a foot switch. The amp has tonnes of head room and can get those nice mesa distortions. I switched to digital amplification a few years back and have kept the amp in storage for when I may use it again. Has had approximately 1 hour playing time the past couple years on the tubes. The amp weighs 55lbs, is very loud and amazing versatile amp and has a nice spring reverb.
