Based on Whisper, AcmeBarGig's clean amp model, Whisper Tube features a 12AU7 tube to warm up the sound. By driving the tube using the "Tube Gain" knob (located above the master volume control), gives Whisper Tube tones ranging from a perfectly pure clean to a smooth, creamy overdrive, designed for lower-gain tones, in particular blues leads and crisp chords. By turning down the "Tube Gain" knob, you can still get the piezo-like tones from the original Whisper.
- Modeled 12AU7 tube for added warmth and overdrive.
- Powerful 3-band parametric EQ tonestack featuring proprietary "Tone Extender" technology.
- Selectable multi-mode filter for final tone shaping.
