The Soldano Avenger Amplifier Head delivers the classic overdrive of the legendary SLO 100. 100-watt head with the SLO 100 overdrive circuit and no channel switching or effects loop to complicate things. This simplified signal path also improves dynamic response for a punchier sound. High- and low-gain input jacks provide the option of using the full SLO lead circuit or skipping the first gain stage for a darker crunch tone. In addition to the preamp gain, bass, middle, treble, master volume, and presence controls, a depth control is included for boosting low end. A rotary impedance selector switch on the amp head allows the use of 4-, 8-, or 16-ohm speaker cabinets. Like the SLO, the Soldano Avenger uses 5881/6L6 power tubes.
