The T-Rex Purist is a small outboard bass preamp that really enhances your tone.
Just plug your bass into the box and then go from the box to your amp/or direct to the board.
The Purist is perfect for vintage basses where installation of an onboard preamp would affect the instruments original condition and resale value.
The Purist is recommended for all passive basses, basses with active pickups, and instruments that have active electronics that can be bypassed. It also works great with all upright bass pickups.
The Purist weighs next to nothing. It is fitted with a strong brace on the back, enabling you to wear it e.g. on your belt.
The Purists controls consist of volume, treble boost and bass boost, and it can be bypassed by pressing a push-button in the bottom of the housing-case.
