Overloud Choptones Brit J71 TH-U Rig Library is an expansion library for Overloud TH-U guitar amp simulation software (will also work with TH-U 'Editions'). Created by Choptones, it seeks to recreate the sound of a 1971 Marshall J 100W*.

Overloud borrowed this amazing Marshall '71 from a dear friend of theirs that stated it will provide 200 Watts... and it actually did. A big monster with unbelievable tone and texture. Explore this Marshall classic with the most complete capture by Choptones.


The original amp features 4 inputs: I and II with a darker tone, Low and High sensitivity, each one with its unique tone. In addition, inputs I and II are ofted bridged to expand the tonal capabilities. All the input configurations are in this library.
