This is a modified Fender Bassman 35X converted into an amp head. A friend built this as a learning project, and I've been using it indoors. However, I've acquired a genuine Fender amp head, so I'm reluctantly selling this one. Currently, there's no crackling, but please be aware that this is a modified, one-off unit. The price is set higher than the market average, but this reflects the cost of the modification parts and labor, so please understand. Thank you for your consideration. - Model Name: Bassman 35X - Brand: Fender - Input Type: Passive/Active - Controls: Volume, Contour, Treble, Middle, Bass - Headphone Output: Yes - Power Switch: Yes
