In More Detail

The Rockerverb 100 MKIII isn’t just big, it’s versatile too. It gives you all the tonal depth and richness you’d expect from a 100-Watt all-valve head, plus the flexibility to tailor your output for the venue, session, or song. The Clean channel stays rich and articulate at high volumes, while the Dirty channel offers a huge range of gain, from classic crunch to modern saturation.

The footswitchable valve-driven spring reverb adds space and shimmer, while the built-in attenuator lets you achieve power-amp distortion at manageable levels. And thanks to switchable output power, you can drop to 70W, 50W, or 30W to suit your needs. Pair that with rock-solid UK-built transformers and a transparent valve-buffered FX loop, and you’ve got a head that can handle anything you throw at it, with tone to spare.

Highly versatile twin-channel design

The Rockerverb 100 MKIII’s independent Clean and Dirty channels are designed to handle any genre or playing style. The Clean side remains bold and articulate at high volumes, while the Dirty channel offers everything from bluesy grit to bone-crushing high gain. With separate EQ controls and footswitchable operation, this is the most adaptable amp in Orange’s arsenal.

Footswitchable attenuator and valve-drive spring reverb

The MKIII features a footswitchable global attenuator that lets you push the power amp for natural valve breakup even at lower volumes. Pair that with the lush, valve-driven spring reverb (also footswitchable), and you’ve got studio-level dynamics and ambience at your feet.

Switchable output power

Don’t let the 100 watts fool you — this amp is built to flex. Choose from 100W, 70W, 50W or 30W modes to fine-tune your feel and response. Whether you need full headroom for festival stages or smooth compression for smaller venues, the Rockerverb 100 MKIII delivers the goods.
