Product Description

The Rockerverb 50 MKIII head combines over a decade of user feedback with numerous improvements to the design. In a first for the Rockerverb Series, the MKIIIs include selectable output power options to manipulate headroom and volume. This 50 Watt version switches down to 25W in half power mode, whilst the mains transformers have also been upgraded better low end response and articulation. The MKIII also features the same footswitchable attenuator that has been so popular with users of the Thunderverb and Dual Dark Series amps.

Orange Rockerverb 50 MKIII Guitar Amplifier Head Features

  • Twin channel Class A/B guitar amp head
  • Footswitchable valve driven reverb
  • Valve buffered effects loop
  • Footswitchable attenuator
  • Selectable output wattage
Celebrating its 10th Anniversary last year, the Rockerverb Series demonstrates better than anything else that a workhorse amp can be a master of all trades. The original Rockerverb was actually Orange’s first ever ‘high gain’ amplifier, with a unique voice that quickly became a firm favorite amongst the heavy crowd. However, its supreme versatility and dependability meant the series has been a mainstay for touring artists and session aces, both on the road and in the studio.

The Clean channel has been revoiced on the new MKIIIs for a more ‘chimey’ response. The clean side now has even greater headroom than previous models, whilst still retaining the warmth and vintage character of a non-master volume design. Also, the valve driven spring reverb now has a more extensive range with a brighter trail. Add to this a host of other hidden refinements and you have the finest sounding and most feature-laden Rockerverb to date.

Highly Versatile Twin Channel Design
The original Rockerverb gained a cult following on account of its iconic high gain tones. The MKIIIs of course continue this tradition, but these amps are immensely flexible. The Dirty channel goes anywhere from classic British crunch to the very heaviest modern genres, and always maintains outstanding clarity.

The non-master volume Clean channel has been re-engineered to take on a more ‘sparkly’ and ‘crisp’ nature but with greater control through a revoiced two band EQ section. The MKIIIs have even greater headroom and volume in full power mode should you need it, but this can now be manipulated with the amp’s output power and Attenuator controls.

Footswitchable Valve Driven Spring Reverb
Driven by a pair of 12AT7/Ecc81 valves and a custom transformer, the spring reverb circuit in the MKIII has undergone significant upgrades. It is Orange’s richest sounding spring reverb design to date, with a more intuitive and usable sweep, ranging from subtle ‘air’ to full-on surf.

Footswitchable Attenuator Control
Output stage saturation at ‘conversation volumes’. The Attenuator circuit is located after the master volume controls and determines when and how the amp distorts after the preamp stage. This means the overall volume level can be reduced, whilst keeping control over the amp’s output clipping characteristics.

Unlike a loadbox, this design ensures the all-important relationship between the output transformer and the speaker remains intact, so even at very low volumes the amp remains springy and responsive. Turning the Attenuator control clockwise reduces the overall output level (i.e. increases the attenuation), which can be remotely defeated via a footswitch for a volume boost on either channel for lead lines.

Switchable Output Power
Switching the amp’s output power allows for more control over the headroom and breakup from the output valves. Reduce the output for greater output valve clipping and saturation at lower volume levels. The Rockerverb 50 MKIII features a ‘half power’ mode which drops the plate voltage on the output valves, reducing the output power to 25 Watts.

Valve Buffered FX Loop
For the purist who loves their pedals, this highly transparent effects loop is buffered by a single 12AT7/Ecc81, ensuring an all-valve signal path from input to output.

Very versatile amp
Product Rating
What is your opinion of this product?
This amp can cover alot of ground. It is more modern sounding than my Orange OR50 with more highs in the 2-4k area. I run a parametric eq to pull those down. The clean channel on this amp is very organic and chimey. The Overdrive/Distortion can take you from slight breakup to a full blown heavy distortion fuzz. The EQ is very responsive and the attenuator works quite well. I wish the amp had more power amp breakup at high volumes as the power section runs pretty clean. Effects loop works very well. The knobs have clicks so you don't have infinite control but works very well gigging and setting up. I run a treble bleed on all my guitars and with this the amp cleans up very very well. Overall its a well build solid sounding amp that has a more modern feel while retaining the Orange sound.

Well worth the money!
What is your opinion of this product?
So, I don't shred, I am not anywhere close to being a metal guy or a classic rock guy which orange amps are known for. I play alt rock/shoe gaze and I took a big leap of faith on this amp. Never heard it live before and really just based my ideas off of reviews online. This amp is beyond what the reviews show and sound like. It literally took me about 15 minutes to dial in an amazing sound. It adapted to my pedals perfectly and I have't even started playing the the FX loop option. I don't have cheap pedals so the amp really has to have a pure clean sound for them to shine like they need too and this amp not only did that but made my pedals sound better than even I expected them too. It's heavy and it's expensive but I will never look back and wonder if I made the right decision. It is more than I could have hoped for. I am running it through a vox 2X12 with green backs for a cabinet. Great sounds and great amp!!!!

Great amp!!!
What is your opinion of this product?
Amp was even better than expected, both gain and clean channels are articulate and amazing. Once you get it dialed in you pretty much will forget about wanting any other amps or pedals!
