The Guyatone GX1 is a compact guitar amplifier with pull-overdrive, equalizer, and reverb functions. Power on confirmed. Guitar connection confirmed. This is an old product, so there is deterioration in various parts. Please purchase only if you understand that this is a used item. The reverb is subtle, but it's an amp that can create quite a flavorful sound. I think it's rare to find one in this condition. - Brand: Guyatone - Model: GX1 - Functions: Pull-overdrive, Equalizer, Reverb - Input Terminals: Multiple input terminals - Power: AC power - Handle: With carrying handle Thank you for viewing.
