Thank you for viewing. This is a VOX bass amplifier 10W PFB-10. It's my brother's equipment, but he wants to sell it because it's in the way. I tested the sound, and there was no crackling. Each knob works properly, and the bright switch also functions. There are no scratches or dents on the amplifier itself, and it's in very clean condition. Use it more, brother! The original box and instruction manual are also included. It has not been used in a smoking environment. The high frequencies are crisp, as is typical of VOX, and the drive knob distorts up to the level of distortion, so it seems usable for any song. The low frequencies aren't very strong. It seems to suit a P-bass better than a Jazz bass. Honestly, it feels better to use it as a guitar amp than as a bass amp. VOX products are stylish as interior decorations, too.
