You know the model, legendary Russian 'Tank' big muff from the nineties.  This one has 9v power supply as well as battery option and comes with its original wooden crate box, all important for collectors value.  No feet or battery cover of course, but plenty of velcro to stick it down.

Perfect working order.  Footswitch and all hardware sound and original, pots not scratchy.

Will ship worldwide. Close offers only please!
