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 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!

Outstanding Amp

What can I say? The Rockerverb's reputation precedes it and that is for a VERY good reason. The pics only aesthetic is classic and timeless (really looks great with a matched Orange cab). The clean channel is very glassy and round with lots of headroom and plenty of punch - breakup is smooth and beautiful when the volume knob is pushed. The RV's cleans are not quite as chimey as Fender or Vox and I actually much prefer them over Fender and Vox. This is subjective, but I find the cleans much more pleasing to the ear and much less 'shrill.' Many people try to compare Orange to other brands and the fact is, you just can't. Orange has a very distinct tone which is what makes them unique! They aren't trying to be something else - they are Orange. As many have said before, the dirty channel is where this amp really shines. I used to have an AD30 and while it is also a truly great sounding amp, it just didn't have that 'special something' that the Rockerverb most certainly does have. The gain is just incredible - very tight low end, lots of midrange punch and very shimmery highs (again without being shrill). Quite simply, it produces one of the smoothest and most 'musical' sounding distorted tones I've ever been lucky enough to achieve and play. The attenuator, complemented by the 1/2 power and 2/4 power tube switches make it usable in any situation from the bedroom to very large stages. As some may have stated the tone loses some of its luster when the attenuator is pushed to extremes (especially at 1/2 plate voltage) but it still sounds awesome. I generally don't use much reverb but it sounds great to me and is very usable in band situations. It doesn't have a super long tail like some fender verbs but IMO those only throw mud in the mix. This has been my dream amp for many years and I am glad I held out for the MKIII version. It looks great, and most importantly sounds amazing. If you're looking for an amp that will cut through with outstanding tone, clarity, versatility and punch, this is for you. It may be on the expensive side but it's worth every penny. I don't think I'll ever buy another amp after this one - if I do it will be another Rockerverb!


I had very high expectations, and I was still totally blown away! I was so impressed that I bought 2 of them. I already have a Marshall 410 Head, and a Peavey 6505 Head, but the King has arrived and its color was Orange. The Rockerverb 100 MKIII is the best amp I have ever owned, and I have owned just about everything there is over the last 40 years playing guitar. The cleans sparkle and shimmer, but the Dirty tones rage from every spot on the dial. Truly remarkable, you need this amp!

Outstanding Head!! Great Tones!!

I recently picked one of these up from Sweetwater and I cannot say enough about it!! Andy Plank is my sales engineer and he took lots of time answering my questions and provided me with real feedback on the amp (He owns one). The sound of the clean channel is unreal. Very "chimey" and "glassy". The gain channel is in a league of it's own!. If you play anything from indie rock to metal the Rockerverb 100 MKIII has you covered. The attenuator is awesome. It allows you to crank the channel volume and get the power tubes working at bedroom levels. I came from a 5150II head and I think there is no comparison. The Orange is just an overall better amp!! And kudos to Andy again!! Proud to now be part of the "Rockerverb Mafia"!!

Its...Amazing and everything youll need.

This amp is Beyond Words. If you want something that can do any thing from Django Rinheart to Sabbath to Deicide, and still be heard over loud blasting drums this is the amp for you. Straight and Simple to the point its just a great electric guitar amplifer. Works great with pedals to. Some amps sound like garbage when you dial the knobs in a certain way, this however will sound musical and alive no matter how youve got it set. Great Reverb and everything you would want to have be footswitchable is. And the Attenuator is my best friend, Ive been leaving the channel volume knobs set at 50% and just adusting the Attenuator and valve output options when i need to switch from jamming with the band and then jamming by myself. Its made in england what can i say. And this amp blew other english amps ive tried out of the water by like 10000000000%

What dreams are made of

First, Sweetwater is fantastic! Shout out to Rich and Nick.Second, this amp is also fantastic. Own a MKII, this is a different amp! Channel 1, Reverb and the ability to attenuate the sound and wattage amps separate it. Channel 2 sounds a lot like the MKII but clearer. Channel 1 has more chime and will suit your needs very well, very Vox in my opinion but an Orange take on Vox. Push the tubes and you get a great crunch sound!Channel 2 is classic RV tone, 4 stages of gain so you can go from a slightly broken up tone to the metal zone very easily.Reverb is much more subtle!! I like it but maybe too subtle?! I like the MKII reverb quite a bit, reminds me of a Fender.Overall it is a wonderful amp, I am very pleased. I did a Rockerverb duel MKII vs MKIII on youtube if you search for that; it might help you make a decision if you are debating between the two amps. You cannot go wrong with either one or an Orange.
