Two-Rock Crystal Amplifier Review

The new Two-Rock Crystal Amplifier lives up to the hype.  As a Two-Rock Studio Pro owner I can vouch that the simple design of this amplifier will appeal to many while still retaining that highly sought after Two-Rock tone.  The benefits of the Crystal are:

• Larger cabinet design without being “too big” in comparison to the Studio Pro 22 combo
• Two-Rock are using Celestion Gold Speakers which to me, sound a lot nicer in the highs and lows.  It sounds way more balanced and open sounding without having too much low end like my Studio Pro head and box has.
• Easy and simple controls.  There’s no extra “crap” like pickup loading, active effects loop, and too many push pull pots.  It’s just simple, loud, and proud.
• If you’re into the high clean headroom amplifiers, this is a go-to if you’re into the Two-Rock tone.

John Mayer Sound

This amplifier model is based on the John Mayer Two Rock Signature Model and I don’t think fans of JM will be too disappointed.  That said, these amps are pretty expensive but they are built extremely well and will suit any style of music.  Even though it has a Gain control on the front, you will need pedals to get the most out of this unless you’re into just “dead clean” tones.

Like all Two-Rock amplifiers, this baby is LOUD.  It’s more than enough for just about any pub/club/bar gig you could ever do even without having to use a microphone through the PA, this is so loud.  I would put this on par with a 50 watt Fender amp in terms of volume and clarity.

In this video demo of the amp above Dr Ric is play-testing the new Two-Rock Crystal Amplifier Combo at Deluxe Guitars in South Melbourne, Australia. This is “closely connected” to the Two-Rock John Mayer Signature series amplifiers that were only made in a short supply run.

This is a new model straight from the USA and we were lucky enough to be the first in Australia to demo it. A huge thanks to Michael at Deluxe Guitars for letting us demo this wonderful amp.

Two-Rock Crystal vs. Fender ’56 Deluxe Reverb

The Two-Rock Crystal 22-Watt Amplifier and the Fender Deluxe Reverb ’65 Reissue offer distinct tonal profiles and playing experiences tailored to different guitarist preferences. The Two-Rock Crystal, with its 6V6 power tubes and 12” Celestion Gold Alnico speaker, delivers pristine, harmonically rich clean tones with a smooth, creamy character and exceptional touch sensitivity, making it ideal for nuanced, dynamic playing in genres like blues, jazz, or modern rock.

Its contour control and lush spring reverb allow for precise tonal shaping, emphasizing clarity and warmth with a modern, hi-fi feel. In contrast, the Fender Deluxe Reverb ’65 Reissue, also powered by 6V6 tubes but paired with a Jensen C12K speaker, produces the iconic Fender “blackface” sound—crisp, chimey cleans with a slightly scooped midrange and a punchy, vintage sparkle. Its tone is more raw and lively, with a tighter low end and a characteristic break-up when pushed, appealing to classic rock, country, and surf players.

The Deluxe Reverb feels more immediate and lively, while the Crystal offers a refined, polished response, catering to players seeking either vintage grit or modern sophistication.
