Brit J1 Preamp is the TH-U expansion library created by Choptones that recreates the sound of a Marshall JMP-1 Preamp*.

This library contains 154 rigs:

  • 26 rigs were created from the 26 factory presets found in the original preamplifier, by connecting the preamp to a JCM800 power amp.
  • 128 rigs were created from setups with multiple cabinets, microphones and overdrive pedals in order to provide a wide range of tones. A Mesa 2:90 power amp has also been used.
