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 100 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 100 MKIII can't take you.

Orange Rockerverb 100 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 MKIII 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 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 100-watt tube behemoth behind us - not on the stage and 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 100 MKIII. With onboard power scaling at 30, 50, 70, and 100 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 100 MKIII is a 100% tube design. The tubes aren't only in the pre 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 100 MKIII Amplifier Head Features:

2-channel, 100-watt high-gain electric guitar amplifier
Revoiced channels go from chimey to grinding
Selectable 30-, 50-, 70-, or 100-watt performance
Footswitchable attenuation for dynamic control
Tube spring reverb offers airy to full-on surf
Buffered tube-driven effects loop
EL34 power tubes and 12AX7 preamp tubes

Go from chimey to grinding and from a whisper to a scream with the Rockerverb 100 MKIII!

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

I could not be happier with this monster of an amp. The Rockerverb has always been a "grail" guitar amp for me, and to now finally have it is just awesome. Sometimes I go into my studio just to stare at it. It's BEEFY, it's dirty, it's chuggy, and it's LOUD!! My 4x12 cabinet with the Eminence speakers I bought from you guys is the perfect match for sludgy stoner doom, to brighter "classic metal" stuff, as well as everything else I throw at it. It sounds so good, my Quad Cortex buddy wants to get a capture of it for himself too. Love it.

I paired this head with a PPC412-A and C, and have it in my home studio office. Playing this beast ruptures the Earth, summoning entities from Hell- whose voices are transmitted via the speakers. The disconcerting sound of dread fills my home, sending all family into panic. Needless to say, this is a wonderful tube amp that transcends both time and space, and creates peace within my soul.

Just buy it. Super versatile being able to to knock down the wattage. The best sounding amp I've ever played through and I've owned pretty much every amp known to man kind. Weighs a ton but worth it especially in a studio environment but even gigging it's worth lugging around thats how good this thing sounds!

I had been in a band where I was the lead singer, I do not play guitar except in the privacy of my own home. I haven't had a real amp in a long time, but I always wanted an Orange (I previously had a 5150). I really wanted the OR100, but it was discontinued. A few years of searching I tried an OR15, and fell instantly in love with the sound, which I believe became my sound. Eventually in my band of 10 years broke up a victim of Covid, after a couple years I had the courage to get back out there and start playing music again, but I wanted to play guitar and still sing of course. I started a new project last summer, and my or 15 really did well on till my other guitar player turned up and I maxed my volume out. I finally had to jump in and get a Rockerverb. First of all I have to give a serious shout out to Colton Smiricky (One of the best sales people I have ever dealt with). The OR sounds very similar to the RV, but I am blown away by the headroom, and the simplicity, and the versatility the RV gave me. With very limited amounts of controls, and options, you can play everything from jazz to heavy metal on this thing, and it kills it, yet without ever losing that Orange tone. The RV 100 MKIII is kind of a Swiss Army knife of an amplifier, without compromising its tone, and I absolutely love that about this amp. The RV100 has some of the best cleans I've ever heard, and when you crank that volume control up you get some really great vintage orange overdrive, The clean channel could be a one channel amplifier in itself, crank the heck out of the volume control and use your guitar volume control to clean it up, and you get such a great classic rock sound from that, add an overdrive pedal and you literally get three usable sounds in any live situation. After all that I have not even talked about the distortion channel. The distortion channel of this amplifier does not try to be anything else except for classic orange overdrive with four stages of gain. When I had my 5150, I was told by my band members that I sounded like I was playing through an orange, heavy on the mid range are used power amp distortion over the preamp distortion, and I kind of did that AC/DC thing on steroids. I really hated that the 5150 kind of became this thing where everyone used it cranked the preamp and it eventually sounded like a boss metal zone. That conversation about my 5150 was back in 2005, and I kind of always wanted to have an orange ever since. This amplifier can be heavy AF or jazz clean, but it doesn't compromise it sound or pretend to be anything that it isn't. I could not recommend this amp anymore, this amp is my voice.

I'm no virtuoso, but I do play live in 2 bands. I've owned both profilers, because I'm nearly 60 now and gigs are getting more exhausting by the minute(Haha) and tube amps. My 3 bands play Lynyrd Skynyrd, AC/DC and Judas Priest. Those are 3 bands far away in the tone department as you could seemingly get, and you'd think perfect for an amp profiler. But there's just something about a full stack pushin' air for Back In Black or piercing ears with Victim Of Changes. During covid, the band decided to rehearse in San Francisco at SIR. Nobody was using it, my buddy Paul is the manager of SIR. I was able to go "AMP" shopping and play any head I wanted, after some testing I couldn't believe how awesome this Orange sounded. So, being like any other musician, I impulsively bought my own! 2 weeks ago, we had our very first live show and my first use of the Orange head in a live show. In the spirit of Y&T, FACEMELTING! This amp is heavy...almost 60lbs, and the tone that comes out of this monster is JUST AS HEAVY. Since this was our first show in years, and all 3 singers (Skynyrd, ACDC, Priest) were there, we tossed in 3 Skynyrd and 6 Priest songs along with 25 AC/DC songs. Changing amp settings in the chaos, wasn't super realistic but I figured I'll just roll with it. I set the amp up for 25 AC/DC, just 3 or 4 on the Gain and my Malcolm Young Signature Gretsch sounded AMAZING...just like cheap version of Malcolm (ie: ME). When the Priest songs came up, I switched to my 87 Charvel Jackson and the Orange without changing a thing with the active humbucker screamed through Devil's Child like Satan himself touched the dials. Then came the challenge, Skynyrd. I took my same 87 Charvel, dropped the active humbucker, switched on the middle pickup, lightened up on the string picking and HOLY HELL, I was headed out towards door with Ronnie. Could I have perfected the tone? Sure...but one amp, 2 guitars, 3 different pick ups all handled flawlessly without touching the dial...just pick ups and string attack for the win. I will keep playing live shows with this monster until I can't pick the head up anymore, and then I'll get a roadie. I love this amp.
