Henry Amplification Metatron
From classic thrash to modern djent and everything in between, the Metatron is our answer for the high-gain player searching for no-compromise tone. Footswitchable Boost can be used to thicken up leads like a classic OD pedal, or beef up rhythm tone for guttural chugging. Clean mode starts out crystal clear, and can be pushed into a classic overdrive like a Plexi Bright channel.
Pasadena Rose
Vol I is a true Non-Master Plexi stage, with full range of tones from warm, detailed cleans, to punchy natural overdrive. Pull Bright for extra shimmer with humbuckers or neck pickups.
- Vol II picks things up from the 1978 Brown Sound explosion through the next decade of Sunset Strip decadence and beyond. Choose between 800 or Mod modes for the ultimate in flexibility (footswitchable).
- 800 mode is designed for a great rhythm crunch, and takes all your boost/OD pedals like a champ worthy of it’s name.
- Mod mode is higher gain for thick, sustaining leads, and rip-your-face-off riffing. Use 800 for rhythms and Mod for a lead boost, or live in your favorite mode… your choice.
- Our unique Master Volume circuit is coupled with Vol II, and additionally a “Jose”-style Saturation circuit on Pull switch to achieve authentic overdrive tones at bedroom levels, or push clipping to the hilt at full power.
- Classic cathode-driven Treble, Middle, and Bass EQ, with additional Presence and Depth controls on rear panel to shape power amp response.
- Rear panel Effects Loop ready for your favorite reverbs, delays, and sound toys of all sorts (Buffered loop optional).
- 50 watts RMS power, 2x EL34 power tubes, 3x 12AX7 preamp tubes
-Available as a small box head (20”L x 9”H x 8”D) in your choice of Red Garnet, Purple Levant, Vintage White, or Classic Black tolex. For custom options, please inquire directly.

Best of Both Worlds: Non-Master Volume vintage tones, along with footswitchable Gain and the most transparent Master Volume circuit possible.
Dynamic, musical, and responsive. While it's essentially a two-channel amp with switchable overdrive, the Gain & Volume controls work a little differently than others, taking you on a trip thru time along the way.
- Many Master Volume circuits can limit and degrade tone... we've gone ahead and designed this amp with that in mind, featuring the most transparent and natural-sounding master volume possible. It’s like a built-in attenuator without any of the drawbacks; Your tone stays thick & chewy with all the harmonic content you could ask for, even at bedroom volumes.
- With OD off, the Volume control functions like a classic 1965 non-Master amp, covering a full range of tones from beautiful, warm cleans to bluesy breakup and fully-cranked Plexi tones at max. Try some Jimi with a Strat here, or grab a Les Paul and crank it to 10 (the Mid control sounds great boosted here too, just like an old Marshall).
- With OD engaged, the Gain picks up and takes you into the next decade, where overdrive builds on the clean foundation like a warm blanket, and gets thicker and chewier along the way. Some of the in-between tones are really killer here, maintaining clarity along with some dirt & drive. Plug in a Tele for some Keith, or humbuckers for Eric… they’re all here. Set the Volume where you want it for clean tones and switch in the Gain for dirt, or crank the Volume for a classic dirty rhythm tone and push it over the top for leads.
- Rear panel features Presence, Depth, FX loop, footswitch jack, 3-way impedance selector, and dual speaker outputs.
RatingsPros:Vintage Vox brillance. Taut lows and ample headroom. Lovely trem and reverb. Cons: A bit pricy for a 10-watt combo? Street: $1,995 Henry Amps SRT+ henryamps.com | Tones:  Ease of Use:  Build/Design:  Value: |
The SRT+ from New Jersey’s Henry Amplification is inspired by an ultra-rare, mid-’60s Vox amp: the AC10SRT, or Super Reverb Twin. This amp has fascinated me for ages—or at least since yesterday, when I read about it for the first time. It was a head-only dual-EL84 model. (“Super” is vintage Vox-speak for amps with separate head and cabs.)
Henry’s SRT+ remains largely faithful to the original AC10SRT, both in circuitry and build techniques. But a few meaningful departures expand the amp’s range and make it more attractive to modern players. These are the “plus” in SRT+. Unlike the original AC10SRT, with its quirky trapezoidal head, the SRT+ head and combo both live in more conventional rectangular cabinetry. Henry offers the head at $1,695. But we reviewed the $1,995 combo with its terrific-sounding 12" Warehouse BlackHawk alnico 50-watt speaker—an upscale model that sells for $240.
Fizz Meets Fundamentals
The SRT+ resides in the same tone galaxy as a Vox AC15. Clean tones are articulate and bell-like. High-gain settings yield unmistakably Vox-y distortion, distinguished by fizzy, animated highs and high-cholesterol harmonic saturation.
It can be difficult to pinpoint exact tonal differences between Henry’s 18-watt SRT+ design and 15-watt Vox designs because much of the Henry’s personality stems from its speaker. While the Warehouse BlackHawk employs a period-correct alnico magnet, its relatively high headroom provides low-end punch and definition that you don’t generally associate with low-wattage Voxes.
It’s almost as if some sonic mad scientist stitched together the taut low-end response of a blackface Fender with the edgy presence of an early Vox. Meanwhile, the high headroom means you can smack the amp’s input with distortion pedals without making tone oatmeal. This is a fuzz-friendly amp.
A light and resonant solid-wood cabinet disperses sound evenly. It’s a detailed, all-enveloping sound, and loud enough for small stages unless you’re playing in a noisy environment with an aggressive drummer.
Shaken, Not Splashed
The amp weighs 40 pounds, which may seem heavy for a 18-watter. But the hefty custom-wound Heyboer transformers and relatively weighty alnico speaker more than compensate in performance for the hassle of extra weight. The rectifier tube is an EZ81. Like the original, the SRT+ offers tube-driven bias tremolo—another quintessentially Vox characteristic. The trem’ rate doesn’t get unusually slow or fast, but it sure goes deep. Maxed out, it yields a hard, square-wave-like chop. You can really get lost in the dreamy modulation.
There’s also tube-driven spring reverb. The reverb tone is warmly inviting, but its effect is subtle compared to, say, 1960s Fender reverb circuits. Its somewhat dark tones sit tidily behind the dry signal and sound great at all settings. Just don’t expect over-the-top splashiness. Here, the original’s wet/dry control is supplemented by a dwell control which regulates drive into the reverb tank. There’s a rear-panel jack for activating the trem and reverb. You hear the full range of the trem and reverb controls over the course of the demo clip, online.
Small Controls, Big Drama
The second reverb knob isn’t the only new control. There’s also a 3-position toggle that trims varying amounts of low end at the amp’s input. Presumably, the low-cut settings are designed to manicure sloppy lows when using humbuckers. But I found all three settings useful with both my demo guitars (a ’63 Stratocaster and a DIY guitar with vintage-style PAFs). This bass cut switch interacts beautifully with the single high-cut tone control. These two simple tools can generate a remarkable number of tones. I certainly didn’t miss having a mid control or a bass-shelving tone pot.
The grayish “blackened catfish” vinyl on our review model echoes vintage Vox, as does the diamond-patterned grille cloth. White knobs on a reflective black control plate provide attractive counterpoint. The interior work is strictly traditional, with components hand-soldered on turret board and chassis-mounted pots and jacks. The wire work looks dependable, if not as fastidiously neat as on some ultra-premium amps.
The Verdict
What’s cooler than a lovely modern-replica version of a favorite vintage amp? Maybe a lovely replica of a vintage amp that’s flown under the radar? With its high headroom, stout 50-watt speaker, and simple-yet-effective tone controls, Henry’s SRT+ is no strict ’60s throwback. It melds some of the most beloved attributes of early Voxes with musically meaningful updates, not to mention extraordinary muscle for a 18-watt combo. Its tones are both familiar and fresh—and a pleasure to play with.
