The Sonzera 20 is a moderate power 20-watt combo amplifier with two independently switchable channels designed for maximum versatility. The Clean channel delivers full, 3D tones reminiscent of American amplifiers from the mid-1960s. The gain channel is circuit-related to the Clean channel, so it can be set as an amplified clean channel or manipulated to make the channels sound like two completely different amplifiers (the gain channel can be linked to the Drive and Level channels). Controls can be adjusted from slight to very strong distortion). The gain channel's Bright switch has been carefully tuned to deliver the usual high-end kick and is particularly effective on low strings, neck pickup settings and single coils, while the gain channel is full, tight and tight in the lower range sounds clear. Both channels of the Sonzera are designed to maximize note clarity and definition. The global presence control and tone controls allow the guitarist to select a variety of tones, from bell-like to warmer, fatter sounds. The Sonzera 20 Combo also features a global spring reverb control that highlights notes without muddying them. The reverb can be switched on and off using the footswitch. Thanks to the built-in effects loop, players can easily use all time-based effects without affecting the overall sound of the amp. The Sonzera 20 Combo is a solid amplifier for live performances and studio use, which is characterized by its robust construction, wide range of sounds and good controllability.
