Re: How much would you pay for a 77 Marshall superlead
From that year, the most common is 2 input MKII's. If it's a Superlead, it'll be a rarer 4 input non master amp. You don't see those too often, but they exist.
The head is worth around $1700, and the cab around $1100. Price really depends on the seller's motivation. It's easier to buy from older players, than savvy collectors.
