The Runt-20 is a versatile 20-watt head that delivers Friedman's legendary tone from a compact two-channel amp. The power section is driven by two EL84s, and the preamp features three 12AX7s. 
A clean channel features a volume knob and three position bright switch that delivers singing cleans to slightly broken up tone. 
However, the heart and soul of the Runt-20 is the overdrive channel which will take you from classic rock to all out assault. A Boost switch and Gain knob to dial in the perfect amount of overdrive.  Plugging into the Runt-20, you will instantly notice the harmonically rich detailed chords and resonating single note lines. This amp cleans up exceptionally well with the guitar’s volume knob, even with the amp on higher gain settings.
The Runt-20 delivers the tight bottom end and midrange that is typically only found in much higher wattage amps and is ideal for many styles of music from blues to classic rock and heavy metal by merely adjusting the gain and master controls.

Perfect for recording in studios or noise sensitive environments, the Runt has an internal load and XLR cab simulated output. This allows an output you can proudly send to front of house, use in the studio, and/or play "silently," meaning you can plug and play the amp without having a speaker cabinet connected. The XLR output includes a ground lift, level and center / edge of speaker cone simulation switches.

An Effects Loop is a buffered series effects loop  that takes time-based effects pedals and rack units as well boosts, ODs, phasers, flangers, tremolos and wahs that lie in front of the amp.
