This is the Dirty Tree Boost pedal. We have both the Green and the Black variations.
Combining 2 pedals that are either hard to find or too expensive into one small box.
2 colours options available
The toggle switch controls the tone stack functionality.
When in TC mode the tone stack is enabled.
When in DT mode the external tone stack is disabled and the tone stack is fixed using carefully selected capacitors and resistors to nail that tone that is otherwise unachievable.
Use this into that big high gain tube rig to get those beloved modern metal tones.
Using an internal charge pump it boosts that 9VDC up to about 33VDC
Internal non-sacrificial reverse polarity protection and power filtering ensure that this pedal can be used with any 9v power supply with negative centre jack (BOSS style)
