The Tweaker 88 is a quasi four channel (2 channels with individual boost), 88-watt amp driven by two robust KT-88 power tubes and four hand selected 12AX7 preamp tubes. Recently awarded the coveted Guitar Player’s Editor’s Pick Award and Guitar World’s Gold Award, this flagship amp allows you to personalize every aspect of your tone. The thirteen on-board Tweaker switches offer a seemingly endless palette of tonal variations. The boost channels can either be set for clean boost or volume + gain boost for your soaring solos. From lush classic clean to all out shred, the Tweaker-88 has the power and control to satisfy your jones for tone. A rugged 4-button footswitch is included. 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. Dimensions: 8.24'' (D) x 23.5'' (W) x 9'' (H). Weight: 32lbs
