This is the really rare Mark 1 version of the Marshall Lead 12. The one everyone searches for. Its crunchier and more distorted than the later versions (in a good way). Perfect recording or live amp. The original small 10" was pulled and a 12" Vintage 30 was added decades ago. It now handles low tunings and deeper guitar with ease. The issues are, the mid control is stuck. Its stuck where i left it years back and sounds great there, but i feel it might need some lube or a new pot. Also, the salt n pepper grill cloth is not original, probably done when the speaker was upgraded. The middle of the grill cloth is sagging slightly inward. I'm sure it could be tensioned if need be. The high/low inputs are strange. Low is more gain and volume, which is not right. As is, it has massive amounts of gain and volume on the low input. Less on the high. If you're looking for a bedroom/studio amp with that Marshall distortion, this is the one.
