Posted on April 13 2022
As a vintage amplifier buyer, I'm always on the hunt for great guitar amps from Fender and Marshall from the 1960s and early 1970s. I received a message from a gentleman in London, UK about a nice 1973 Marshall Lead & Bass 20 amplifier that he was interested in selling. As luck would have it, I was on my way to London on vacation! We arranged a meeting for me to take a look and buy the Marshall amp.

Marshall Lead & Bass 20
The Marshall Lead & Bass 20 amplifier is a rather uncommon model which appears to have debuted in 1968. It features a 20 watt head that sits atop a smaller cabinet than typical Marshall cabinets and features only one 12" Celestion G12M (greenback) speaker. Many were sold with black pleather covers for both the head and the cabinet like this one. This example has both the gold aluminum faceplate and JMP brand; both features are indicative of early 1970s Marshall. It utilizes two 12AX7 (ECC83) preamp tubes and two EL-84 power tubes with a solid state rectifier.
There is a great book on vintage Marshall amplifiers with loads of great information on model identification and dating them: The History of Marshall: The First Fifty Years. The section on the Lead & Bass 20 is funny because it mentions that the model wasn't listed in any catalog, but shows a catalog scan showing the exact model just above the paragraph. The image of the Lead & Bass 20 shows typical features for 1968 and 1969. I am actively a buyer for a 1968 Marshall Lead & Bass 20. Do contact me if you are looking for how much it is worth or who buys Marshall amps?
