Paul Reed Smith PRS MT 15 - 15/7 Watt, 2-Channel, Tube Amplifier




15/7 Watts (Switchable) 2 Channels 6L6 Power Tubes

Lunchbox Hero
“We knew we wanted a low-wattage amp. The challenge was getting a lot of tone and features in a little box. We’re all blown away with how it turned out. It’s going to be great for someone to take it out of the box, set everything to noon, and have it sound great.” – Mark Tremonti

The MT 15 is a commanding two channel amp with balanced aggression and articulation. Powered by 6L6 tubes, the MT 15 has a large, bold sound, so you can dig in heavy with rhythms but also get singing lead tones out of one amp. Whether recording, practicing, writing, or playing a small room, this amp has everything you need.

The MT 15’s design started with heavier players in mind, but in the end, it has a lot to offer players of all genres. Like the PRS Archon amplifier, the MT 15 features five gain stages before the Master for full, lush distortion. The gain channel gets big, chunky tone with massive, tight low end, but it never loses its articulate note definition or great lead tone. The clean channel is bright and chimey, good with chords and fingerstyle playing – whether with a pic or not. The clean channel also features a push/pull boost control that adds a little overdrive for old school crunch. No matter what tone you dial in, the MT 15 stays balanced across the spectrum with a sweet, smooth tone that won’t bite your head off.

Additional features include an effects loop and bias adjusters that are accessible from the back panel for ease of servicing. Despite its 15 watts, the MT 15 sounds more like 50, so a half power switch that takes the MT to 7 watts is a welcome addition. Bottom line, the amount of features, the hugeness of the sound, and the raw horsepower of the circuit make the MT 15 an impressive lunchbox hero.

The MT 15 is Mark Tremonti’s first signature amplifier.

Paul Reed Smith PRS Sonzera 20 1x12 Combo



Sonzera 20

Clarity & Definition in a Low-Wattage Combo
Sonzera [Portuguese]: from som (sound), meaning a cool and/ or stunning sound (in the sense of music) – a kind of slang.

The 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 1960’s and 70’s 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 singlecoils, 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.
