OUR PART # RK100HTC-MKIII
Way back in 2014, Orange Amplification's Rockerverb series celebrated 10 years of being the go-to workhorse amplifier series for touring acts and studio cats alike. The Rockerverb 100H MKIII head builds on the decade-long legacy that came before it, and refines that legacy with much-requested features and improvements.
In a first for Rockerverb series, the MKIIIs include selectable output power options to manipulate headroom and volume, and with this 100 Watt version capable of switching down to 70, 50, or 30 Watts. The MKIII also features the same footswitchable attenuator that has been so popular with users of Orange's Thunderverb and Dual Dark Series amps.
The Clean channel has been revoiced for the MKIII models 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 tube-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 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, while keeping control over the amp’s output clipping characteristics. Unlike a loadbox, Orange's 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 tubes. Reduce the output for greater output tube clipping and saturation at lower volume levels. The Rockerverb 100H MKIII features both a ‘half power’ mode which drops the plate voltage on the output tubes, and a 2 or 4 tube selector switch for a choice of 100, 70, 50, or 30 Watts.
Footswitchable Tube Driven Spring Reverb
Driven by a single 12AT7/Ecc81 tube 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.
Tube Buffered FX Loop
For the purist who loves their pedals, Orange's highly transparent effects loop is buffered by a single 12AT7/Ecc81, ensuring an all-tube signal path from input to output.
