(Management number: mw00572tpj) DSL1 guitar amplifier with an 8-inch speaker. Allows for a wide variety of sound creation. - Brand: Marshall - Model name: DSL1 - Input terminals: 1/4 inch jack - Controls: Volume, Gain, Treble, Middle, Bass, Reverb, Equalization - Power supply: AC power - Speaker size: 8 inches Thank you for viewing. I am selling this because I no longer need it. Operation is not a problem, and the knobs and switches on each part function normally. There are no noticeable scratches or stains. This amplifier has a LOW POWER switch on the back, so you can play it without losing the feel of the vacuum tubes, even at relatively low volumes. The only included accessory is the power cable. There is no footswitch. Thank you for your consideration.
