Orange Rockerverb 50 MKIII - 50-watt 2-channel Tube Head
In Stock!

The Most Versatile Rockerverb Yet!

In the early 2000s, a new era of high-gain Orange Amplification tone was ushered in with the Rockerverb series of electric guitar amplifiers. The all-tube Rockerverb 50 MKIII is the culmination of over a decade of fine-tuned adjustments to that game-changing amplifier. The MKIII offers a newly-voiced clean channel for a more versatile chimey tone, and a dirty channel that will take you anywhere from classic British crunch to the very heaviest in modern metal. Add in power-scaling and footswitchable attenuation and there's nowhere the Rockerverb 50 MKIII can't take you.

Orange Rockerverb 50 MKIII Amplifier Head at a Glance:
  • Revoiced dual-channel design for maximum versatility
  • Dynamic control with power-scaling and footswitchable attenuation
  • 100% tube-driven including spring reverb and the effects loop
Revoiced dual-channel design for maximum versatility

While the Rockerverb guitar amplifiers have been a staple in many guitarist's rigs for years, the MKIIIK design ups the ante with revoiced channels to get even more versatility, clarity, and headroom. The clean channel now features a dual-band EQ and higher headroom while also maintaining the vintage character of it's non-master volume design. The dirty channel is engineered to bring the filth, starting you in crunchy rock 'n' roll territory and throttling you deep into modern high-gain grind.

Dynamic control with power-scaling and footswitchable attenuation

In a world of high-tech PA systems, digital modeling, and low-wattage lunchbox style amps, sometimes us guitarists can't get away with a screaming 50-watt tube behemoth behind us. Not on the stage, and definitely not in the studio. Now you don't have to give up the feel and tone only offered by those muscular amplifiers with the Rockerverb 50 MKIII. With onboard power scaling at 50 and 25 watts, you can get those power tubes cooking at volumes that tailor to your situation. And the footswitchable and variable attenuator on the front of the amp can get you those cranked tones at bedroom-level volumes!

100% tube-driven including spring reverb and the effects loop

Nothing sounds like a tube amp... nothing. Orange knows that, which is why the Rockerverb 50 MKIII is a 100% tube design. The tubes aren't only in the preamp and power sections, either. The onboard lush-sounding spring reverb and buffered effects loop have both been dialed in to give you a more clear, organic, and usable tone - all with the power of 12AT7 tubes. While there are a lot of great-sounding options out there to take you out of the tube world, just remember, nothing sounds like a tube amp... nothing.

Orange Rockerverb 50 MKIII Amplifier Head Features:
  • 2-channel, 50-watt high-gain electric guitar amplifier
  • Revoiced channels go from chimey to grinding
  • Selectable 25- or 50-watt performance
  • Footswitchable attenuation for dynamic control
  • Tube spring reverb offers airy to full-on surf
  • Buffered tube-driven effects loop
  • 12AX7 preamp tubes and EL34 power tubes
Go from chimey to grinding and from a whisper to a scream with the Rockerverb 50 MKIII!

Flexible and Quality!

I shopped around for an upgrade from a Marshall JMD:1 head (one of the only Marshall modeling amps) for about a year. I was originally looking for something in the 30-35 watt range so I ignored the Rockerverb because it's advertised as a 50w head, BUT the attenuator and the half-power setting (which aren't highlighted too well in the description) had me sold! The tone of the amp is extremely versatile, dirty channel can get a nice classic/indie rock tone in the low-medium gain (perfect for drum/bass focused songs) crank the gain a little more and you have something worthy of modern progressive and metal! The clean channel is chimey and clear, if you throw and overdrive pedal on it for a little character you have a wonderful bluesy sound. Something I wasn't used to is the pots on each switch: they aren't a smooth, free-spinning pot like other amps. The pots seem to have notched settings, which takes some getting used to, but that's in no way a bad thing, just unusual. I like to go through any and every genre, from twang, to folksy, to alt-rock, to heavy and this bad boy does it all and you can get reasonable home-friendly volumes using the attenuator without sacrificing the tone! Awesome amp, I'd highly recommend it!

Amazing Amp!

I didn't get this through Sweetwater :( I wish I had. I got it by trading a friend for it. Mine is the MKii version, also. I have to say that this amp is the best amp that I have ever played on. Amazing sound, power, and clarity. You can not go wrong with this amp.Now, I said that I wish that I had bought it through Sweetwater, that is because there is not a greater company out there for musicians to deal with. They stand behind their word, their products, and their prices. I have been a huge Sweetwater fan for some time now.Do yourself a favor and get this amp, and get it from Sweetwater. Tyler is my guy, and he is a good one.

Phenomenal Amp - Orange Rules!

For a family cash flow issue I was forced to sell my dream amp - a Dual Dark 100. Soon after, I was able to invest in another head and decided on the RV50 to save a little coin and get reverb with it. I was worried that it would never be able to compete with the DD100 in terms of gain on the dirt channel, but I soon learned that it has plenty of gain for my needs. I play mainly hard rock/classic metal and, come to think of it, I rarely had the gain above 6.5 on the DD100. I get all the gain on the RR50 at about 7.5 - still some to spare.Now, here's where it offers something that the DD100 doesn't - a great clean channel. It's not like I NEVER use clean and the DD100 was very mediocre in that respect. The clean on this head is VERY GOOD...not a Fender clean, more similar to a Vox clean, but it is definitely a great Orange clean. The only half point deduction on my review is for the reverb - it's just OK, not too great in my opinion. It's not awful, but it's tough to dial in a nice amount and if you twist the knob too much it gets too "springy". I would probably have preferred a good digital reverb.Summing up, you get a really nice clean with plenty of headroom as well as, of course, that GREAT ORANGE DIRTY tone! It just maintains clarity with gobs of gain. It seems to help a bad guitar sound good and a good guitar sound great. I've had Marshall's, Bogner's, Mesa's, Peavey's, Blackstar's, Egnater's, EVH's - you name the gainy amp and I've probably owned one or more of their products. For the past few years I've owned an Orange and they've become my go-to amp. They're getting to develop quite a following - and with good reason. To my ears, whatever "IT" is - THEY HAVE IT!
