PRS Sonzera 20 is a 20-watt combo amplifier with two independently controlled, footswitchable channels designed for maximum versatility in the spirit of vintage amps that allowed you to control your tone rather than 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, on neck pickup settings and with single coils, while the low end response of the lead channel is full, tight and clear.
Both channels on Sonzera 20 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 designed to enhance notes without clouding them. The reverb can be turned on and off via the included 2-button footswitch.
The built-in effects loop allows players to use all their time-based effects without negatively impacting the overall tone of the amp.
In addition to its versatile tone, 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, Sonzera 20 Combo is a solid gig- and studio-worthy amplifier.

PRS makes no other express warranty of any kind whatsoever. All implied warranties, including warranties of merchantability and fitness for a particular purpose, exceeding the specific provisions of this warranty are hereby disclaimed and excluded from this warranty. Some states and/or countries do not allow the exclusion of implied warranties so that the above may not apply to you.
PRS shall not be liable for any special, indirect consequential, incidental or other similar damage suffered by the purchaser or any third party, including without limitation, damages for loss or profits or business or damages resulting from use or performance of the instrument, whether in contract or in tort, even if PRS or its authorized representative has been advised of such damages, and PRS shall not be liable for any expenses, claims or suits arising out of or relating to any of the foregoing.
If at any time during the warranty this amplifier malfunctions due to faulty materials and workmanship, PRS Guitars will, at its sole discretion, repair the defect without charge or replace it with a model of similar specification and value that does not exceed the original purchase price of the amplifier.
To obtain warranty assistance, this guitar must be taken to an authorized PRS Guitars dealer with a copy of the sales receipt to obtain a Return Authorization prior to return to the factory.
All shipping and insurance, including any perceived 'collector' value, are the sole responsibility of the original purchaser.
