Pro Tone (2005-2006)

The Mach II Has Been Reborn!

The Mach II consists of 2 Thruster circuits, 2 foot switches, 2 LEDs, and 3 knobs- oh yes folks 3 knobs... all in one little box!

You now have total control over the Mach II's gain stages. In addition, you also get a Master control that allows you to use it as an overdrive/distortion unit without changing your signal volume.

  • Stage 1: This gain stage is a regular Thruster... not that there is anything regular about the Thruster, but you get the idea. Stage 1 has no Master Volume control, it feeds into Channel 2, which makes full use of the Master Volume control.

  • Stage 2 and the Master- Stage 2 is made up of the exact circuit as stage 1, but is fed from the output of Stage 1, and then goes directly to the Master control. The Master control allows the user to keep the output volume under control when stages 1 and 2 are set high.

  • The Master control is operational when both channels are on, or if only Channel 2 is on. There is no need for it to be active with only Stage 1 active.

Usage Tips: The Mach II provides a total of four volume settings, going from clean to wildly distorted.

  • Setting 1: The Mach II is TRUE BYPASS so this would be the sound of just your guitar and amp, both stages of the Mach II are OFF.

  • Setting 2: Stage 1 is active, giving a beautiful full spectrum boost to your signal without coloration.

  • Setting 3: Stage 2 is active, Stage 1 is INACTIVE. This configuration is easy to achieve as both stomp switches are spaced close enough to easily switch them both at once or to alternate between the two stages.

  • Setting 4: Stage 1 and Stage 2 are active sending out a stream of boosted signal bliss, or loud tonal chaos (which is a good thing).
