About the Soldano Avenger 50W

First of all, the Soldano Avenger 50W is a stripped-down 50-watt amp head with the legendary SLO 100’s overdrive. It uses 4 x ECC83 and 2 x 6L6GCs just like the SLO 100. Its design is focused purely on overdrive tone.

Most importantly, the Soldano Avenger 50W has no channel switching or effects loop to complicate things. So, stripped to the bone, this simplified signal path improves dynamic response for a powerful and punchy sound.

Due to the high and low gain input jacks, you can use the full SLO lead circuit or skip the first gain stage for a darker crunch. 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 allows the use of 4, 8 or 16-ohm speaker cabinets.

Built at Soldano Custom Amplification, the Soldano Avenger 50W is made of the best parts available. Carefully assembled by hand from start to finish to create one of the highest quality and most reliable guitar amplifiers. Every step of assembly is done by one technician, no assembly lines.
