I bought a vibrolux reverb the other day, and the seller threw in this monster to sweeten the deal a little. Looks like a 70's 100W marshall, right? But hey, something's off about the pilot light: And when you take a look at the back, you'll see that you can't judge a book by its cover, or to be more precise, an amp by its cabinet: That's no Marshall! The amp tech who is working on the vibrolux thought it might be a London City or sound city amp that was put in an original Marshall head shell. These amps are cheaper Marshall clones that are quite common around here in the Netherlands. It looks like the cabinet was somewhat modified to fit the oversized amp: The amp is not in working order by the way. If it is a London City or Sound City or similar, it's probably not worth fixing her up (at least in terms of monetary value). What do you guys think the head shell might be worth?
