Peace Hill FX's homage to John Mayer's clean tone!
The Peace Hill FX TRJM tube preamplifier is inspired by Two-Rock's pursuit of beautiful clean tones.
Just like a Two-Rock, the Peace Hill TRJM offers a 3-band EQ and 3 mini switches, allowing for a super wide range of tones.
By placing the TRJM last in your effects chain and plugging it into your amp's FX Loop, you can get amazing Two-Rock-inspired tones anywhere!
In addition to using it in an FX Loop, the TRJM can also be plugged directly in front of an amp for beautiful tube tones.
Using it into the line input of an audio interface also gives you rich, natural tones when recording.
Whether you're at home, practicing with headphone or in the studio, the Peace Hill FX TRJM is an amazing tool for beautiful, tube-y tones!

• Gain : Adjusts the input gain to the preamplifier.

• Mid : Boosts the midrange.
• Deep : Lowers the center of gravity of the sound for a deeper tone.
• Bright : Adds high frequencies to the sound. Turns off when Gain is set to maximum.
