VOX Valvetronix VT30, a 40W guitar amplifier. - Brand: VOX - Model: Valvetronix VT30 - Output: 40W - Power: 100V 50/60Hz Thank you for viewing. I acquired this here previously, but I'm selling it because I want another amplifier. There is no crackling, and there are no issues with the sound. The only included accessory is the power cable. It's a beautiful item, but please understand that it is a used item before purchasing.
