"The Orange Rockerverb MKIII is the latest incarnation of the famous Rockerverb series. It started out as Orange's answer to high gain amplification but proved itself to have such a versatile tone that it has no genre boundaries. Orange have taken their much loved amplifier and listened to the consumer and added improvements to this incredible amplifier that make it all the more usable and unrelentingly fun to play.They have tightened up the gain section giving it a much crisper tone that keeps note clarity well even through the higher end of the gain range. It also has an attenuator circuit built in allowing you to drive the amp's volume to reach that perfect point yet still have it at a reasonable playing volume when not playing arena-sized venues. Couple this with the half power mode and the attenuator being footswitchable, this gives you plenty of tone and boost options for use in a live setting.

The definitive two channel 50W head, made better
Celebrating its 10th Anniversary in 2014, the Rockerverb Series demonstrates better than anything else that a workhorse amp can be a master of all trades. The original Rockerverb was actually our first ever ‘high gain’ amplifier, with a unique voice that quickly became a firm favourite 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 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 for better low end response and articulation. The MKIII also features the same footswitchable attenuator that has been so popular with users of our Thunderverb and Dual Dark Series amps.
The Clean channel has been revoiced on the 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 single 12AT7/Ecc81 valve and a custom transformer, the spring reverb circuit in the MKIII has undergone significant upgrades. It is our 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, our 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, our highly transparent effects loop is buffered by a single 12AT7/Ecc81, ensuring an all-valve signal path from input to output.
Features: Twin channel Class A/B guitar amp head, footswitchable valve driven reverb, valve buffered effects loop, footswitchable attenuator & selectable output wattage.
