Sonzera [Portuguese]: from som (sound), meaning a cool and/ or stunning sound (in the sense of music) – a kind of slang.

The PRS Sonzera 20 is a 20-watt combo amplifier with two independently controlled, footswitchable channels designed for maximum versatility and in the spirit of vintage amps that allowed you to control your tone instead of the amp being in control.

The clean channel delivers full, 3D tones reminiscent of American 1960s and '70s amplifiers. The lead channel is related to the clean channel circuit-wise, so that it can be set up to act as a boosted clean channel or manipulated to make the channels sound like two completely different amps (the lead channel can be set from slight to very heavy distortion by simply using the volume and master controls). The bright switch on the lead channel has been carefully tailored to deliver familiar high-end snap and is particularly effective on the low strings, neck pickup settings, and with single-coils, while the low-end response of the lead channel is full, tight and clear.

Both channels on the Sonzera are designed to maximize note clarity and definition. The global presence control and the tone stack allow players to dial in a variety of tones from bell-like chime to warmer, thicker tones. The Sonzera 20 Combo also features global reverb control that is designed to enhance notes without clouding them. The reverb can be turned on and off via the footswitch. The addition of a built-in effects loop allows players to use all their time-based effects with ease without negatively impacting the overall tone of the amp.

In addition to its versatile tone, the Sonzera 20 Combo is also designed for reliability and serviceability. The power tube sockets are mounted directly to the steel chassis, and no push-on connections are used — all wires are soldered.

With robust construction, a wide range of tones, and steadfast controllability, the Sonzera 20 Combo is a solid gig- and studio-worthy amplifier.

Comments about PRS Sonzera 20 20W 1x12 Tube Guitar Combo Amplifier:

Great build quality and attention to detail. Very quiet in operation. Tone controls have a wide sweep and work well. Great harmonic content on either channel. Quite frankly I've been playing a long time and this is the amp I wish I'd had from the start.

    Comments about PRS Sonzera 20 20W 1x12 Tube Guitar Combo Amplifier:

    Great sounding amp other than the rattling tubes.
    I realize I could re tube and get rid of that for a bit but
    can't rationalize re tubing a new amp.
    Also the standing hum seemed
    much louder than any other amp I own.
    I tried recording with it and between the
    tube rattle and hum the track was ditched.
    I assume that's why it was an open box sale.
    I called customer service and they couldn't tell me
    Why it was returned. That's no good.
    There should be a way to track those issues
    Otherwise you just keep selling folks thsame lemon.

    Greatest! PRS Sonzera 20 guitar amplifier

    Comments about PRS Sonzera 20 20W 1x12 Tube Guitar Combo Amplifier:

    The PRS Sonzera 20 is a very good guitar amplifier. It sound exactly like a FENDER Twin Reverb in terms of providing a clear, realistic sound with plenty of powerful bass response. Unlike the TR, the PRS Sonzera 20 is much more compact and a lot easier to transport. It weighs about 42 lbs. compared to the TR's 62 lbs. This amp uses the same 6L6GC power tubes as the TR. I really like the PRS Sonzera 20 a lot...I'm actually thinking about purchasing a second one as a spare! It's that good!
