Hartke A25 bass amplifier. I purchased it several years ago and have only used it a few times at home. Power-on and sound output have been confirmed. As it has been stored for a long time, there is some dullness on the metal parts and some dust that cannot be completely removed from the felt parts. - Brand: Hartke - Model: A25 - Features: Compact design, handle for easy carrying - Controls: Bass, treble, effects, and volume adjustment knobs - Materials: Durable exterior, metal corner guards Thank you for viewing. <Product Overview> *Quoted from Amazon product information.
