The Tweaker is an ultra compact and amazingly versatile all-tube amp that offers a unique and sophisticated tone with seemingly endless tonal variations via the on-board ''Tweaker'' selector switches. Powered by a pair of 6V6 power tubes, the TWEAKER will set the new standard for gigging micro amps. The gain, EQ and master sections each have a Tweaker switch providing a wide-range of tones from the ultra smooth and satisfying to fully over-saturated lead tones. Hidden inside the TWEAKER is a vast array of tones not usually found in amps this compact. Each of the five toggle switches on the front change the character of the amp. The TIGHT and BRIGHT switches shape the low and high end from soft and smooth to punchy and aggressive. The GAIN switch goes from sparkly clean to an all out high-gain assault. The EQ switch lets you select from pristine American to classic Brit and even the elusive VX AC sound. The CLASSIC/MODERN voicing switch allows you to select either soft and smooth or hard and edgy power tube tone. It's all in there to satisfy the ultimate ''Tweaker''.
