Egnater Tweaker-15 Settings Guide
The Egnater Tweaker-15 is a 15-watt, single-channel all-tube amp with switches for USA/UK/AC voicings, Clean/Hot gain modes, a Tight bass filter, and selectable Class A or Class AB biasing. The switching system lets one amp approximate the character of multiple classic American, British, and AC30-style voicings. It's a Swiss-Army-knife amp for players who need one small amp to cover many styles.
The best Egnater Tweaker-15 settings start with: Volume at 5/10, Gain at 4/10, Bass at 5/10, Mid at 5/10, Treble at 5/10. Adjust from there based on your amp, guitar, and room volume. For Blues (USA voicing): Volume 6/10, Gain 4/10, Bass 5/10, Mid 7/10, Treble 5/10.

Settings by Genre
USA voicing approximates Fender-style clean character. Hot mode at Gain 4, mid-forward EQ. The USA voicing has a looser, cleaner low-end with a scooped mid character compared to the UK voicing — boost Mid to compensate. Class AB for headroom.
UK voicing approximates Marshall character — tighter low end, more aggressive midrange. Hot mode at Gain 6, balanced EQ. Tight switch engaged for tighter palm mutes. This setting is the Tweaker's most convincing Marshall-in-a-box tone.
AC voicing approximates Vox AC30 — bright, chimey, forward in the upper mids. Clean mode at low Gain, bright Treble. Class A biasing for the natural AC30-style compression and bloom.
UK voicing, Hot mode, Tight switch engaged. High Gain with scooped Mids for metal rhythm. The Tight switch tightens the bass response for precise palm muting definition.
Tips & Common Mistakes
- The three voicing switches (USA/UK/AC) are the most important controls on the Tweaker-15 — each produces a fundamentally different EQ response curve. Dial in your EQ after selecting the voicing, not before.
- Class A biasing produces more compression and bloom but also slightly earlier power-amp breakup. For clean tones, Class AB provides more headroom. For pushed blues and classic rock, Class A produces the natural sag and compression that characterises vintage amp character.
