The Egnater Tweaker is a 15 Watt tube amp, available as a head or 1×12 combo, and it has taken the world by storm. The beauty of this amp lies in its simplicity: a single channel design with Bass, Middle, Treble, Gain, and Volume controls. Look a little closer however, and the Tweaker offers a world of tonal customizations…. all of it useful.

A 3-position voicing switch lets you choose between “US”, “AC”, and “Brit” settings. This is not digital modeling. Rather, it is an EQ shaping filter that does an amazingly convincing job of transforming the Tweaker from a Fender style amp to a Vox, Marshall, and back again. A low gain/high gain switch lets you set the range of your gain control. This leads to a nice feeling sweep as you slowly turn up the dial, allowing the Tweaker to produce an incredibly wide range of distorted tones without ever feeling too “twitchy” on the controls. Bright/Normal and Tight/Deep switches allow quick tonal reshaping without fiddling with your EQ dials; ideal for those mid-set guitar swaps.
