100W of pure Plexi Super Lead tone (133 Rigs).

Brit J71 is the TH-U expansion library created by Choptones that recreates the sound of a 1971 Marshall JMP 100W*.

Even though this amp is rated at 100 Watts, Choptones borrowed this amazing Marshall '71 from a dear friend who claimed it would provide 200 Watts...and it actually did! This amp is a big monster with unbelievable tone and texture. Explore this classic Marshall amplifier, now available for the rig player in Overloud's TH-U.


The original amp features four inputs: I and II provide a darker tone with Low and High sensitivities—each one with its own unique tone. In addition, inputs I and II are often bridged to expand the tonal capabilities. All of the input configurations are captured in this library.

The Brit J71 library contains 133 rigs captured using the following gear*:


  • Marshall 4x12 loaded with Celestion G12M, G12M20, G12T75, Classic Lead 80, G12K100, Pre Rola G12M, G1265.
