This is a Marshall MasterReverb30 model 5203, a masterpiece solid-state amplifier from the 1980s, made in the UK. These are becoming less common to see for sale recently. The unit itself shows the character of its age, and while the grille cloth has some tears, I believe it is in relatively good condition. There are no crackles or pops, and it produces the excellent sound of the JCM800 era. It's perfect for home practice, and more than sufficient for studio use or small-scale live performances! Modern amps that can create any sound are good, but please also experience the amps of the good old days! As is common with amps from this era, there is a pop noise (a "thump" when turning on/off). Therefore, please always turn down the volume when turning the amp on or off to minimize stress on the speakers. Thank you.
