Choptones Brit J1 Preamp

The biggest British JMP1-based library, which includes the original presets (154 Rigs).

Brit J1 Preamp is the TH-U expansion library, created by Choptones, seeking to recreate the sound of a Marshall JMP1 Preamp*.

The library contains 154 rigs:

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