Hayden Mini MOFO - 15W Tube Amplifier Head - Black Spatter

Very clean example of a Hayden Mini Mofo 15/2 watt amplifier head. I have owned (original owner) this amp for some time and it has been well taken care of in a smoke free environment. I retubed the amp in July of 2025 (Electro Harmonix el84 and Mullard 12 AX7) - the tubes have probably less than 20 hours on them easily. The amp comes with the carrying case and the footswitch that engages the Mofo additional gain stage.

I have a video here demonstrating that everything works here.
