The YAMAHA GA15II is a compact guitar amplifier with clean and drive modes. - Model: GA15II - Brand: YAMAHA - Features: Clean/Drive modes - Input Terminals: AUX IN - Equalizer: Bass/Middle/Treble - Power: AC power Thank you for viewing. With box In good condition. I am selling this because I got a THR10II. I think it's an easy-to-use amp because it sounds good to a certain extent no matter how you control it. Recommended for beginners as well as intermediate players. Immediate purchase is OK. Feel free to ask if you have any questions.
