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 Attenuator Control

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.

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 to its predecessors. It is the richest sounding spring reverb design to date, with a more intuitive and usable sweep, ranging from subtle 'air' to full-on surf.

Switchable Output Power & Effects Loop

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, and a 2 or 4 valve selector switch for a choice of 100, 70, 50 or 30 Watts. Additionally the MKIII also features a highly transparent effects loop which is buffered by a single 12AT7/ECC81 valve, ensuring an all-valve signal path from input to output.

Reviews

"I always used to think that being in a 'heavier' band meant using niche gear specifically designed for heavy music - until I discovered the versatility and power of the Orange Rockerverb 100 head. After hearing what Jim Root & Wes Borland were doing with these amps, I had to try 'em out. I was sold immediately. It has just the right amount of features, no 'fluff'. The heads do everything you want, and go to places tonally that other amps can't."
