The Rockerverb MK III 50 and 100 Watt Amps have everything you expect from the Orange Rockerverb but with improved functionality.

Improvements include:

• Selectable output power options to manipulate headroom and volume, with the 100 Watt version switching down to 70, 50 or 30W
• Clean channel has been revoiced on the new MKIIIs for a more 'chimey' response
• Footswitchable attenuator
• More transparent FX loop
• Larger, more usable reverb with additional ECC83 preamp valve to power it

Key Features:

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 amps output power and Attenuator controls.

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, the Rockerverb 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.

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 100H MKIII features both 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.

Driven by a single 12AT7/Ecc81 valve 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.

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

So I?ve been playing mine about a month now and it is a great amp. I do like the reverb, cleans and knob controls on the MK2 better. You seem to have to turn the reverb up half to 3 quarters for it to really shine. Only a quarter to half ways on the MK2. The sound of the cleans aren?t as warm or nice on this one but not to say these are nice. The gain on this one is more. A bit more punch. I don?t like the clicking knob notches on this one. It is awesome for easily finding your positions but it lacks the sweet spots you may want to get in between. The attenuater is awesome for driving the tubes at lower levels. Can?t complain there.
