Your Marshall head and Bassman are worth nothing without me using them.
Les Paul, depends on the model, finish and hardware,
JCM 800 depends on the buyer, but goes for a lot in general; I'd try to fuck you on a deal myself,
LPS ?,
Ibanez, nothing,
Bassman ORIGINAL, a lot of money; fucked with, depends. OG speakers don't last long. In fact, I think those are the best parts besides the grill cover. Everything else kind of falls apart with age and gets replaced.
But you do have some money.
Use it before I jack it.
