PRS Sonzera 50 1x12" Valve Combo Amp

EL34-Powered, Gig-Worthy Combo

Written by

Elliot Stent

The PRS Sonzera 50 is a flexible 50-watt valve combo amplifier, boasting 2 independently-controlled and footswitchable channels for excellent versatility.

Driven by a pair of EL34 power tubes and fitted with a high-quality Celestion V-Type speaker, the PRS Sonzera offers a diverse range of sounds that stretch from '60s-style American cleans to saturated British distortion.

2-Channel Design

The PRS Sonzera is designed to cover a lot of sonic ground without being overly-complicated to use, with both channels voiced to maximise note clarity and definition. The Sonzera's clean channel delivers articulate and full-bodied tones that have lots of headroom and can be heard easily over a drummer in a gigging scenario. Featuring Bass, Middle and Treble controls, you can adequately shape the sound of the clean channel to preference.

Channel 2 is related to channel 1 when it comes to its circuitry, meaning that you can seamlessly set it up to offer a boosted clean tone. However, you can also configure it to provide a completely diverse distortion tone - like having two different amps in one! Equipped with a 3-band EQ section too, you can precisely set your preferred sound and even use the gain channel's bright switch to introduce some high-end snap and tighten the lows.

Additional Features

PRS' Sonzera 50 sports a global Presence control, which lets you manipulate the highs of the amp - from warm and subtle, to bright and chimey. The Sonzera 50 Combo also features independent Reverb controls for each channel, which are designed to add some sweet ambience without clouding notes or taking away any clarity. Reverb can be engaged via the included footswitch; perfect for adding depth to solos or space to clean passages when necessary.

Effects Loop

The addition of a built-in effects loop allows you to use your time-based and modulation effects with ease, without negatively impacting the overall tone of the amp. This makes the PRS Sonzera 50 a great pedal platform amp, adding to its versatility.
