Orange is auctioning off an OR50 amp head signed by all three members of Biffy Clyro – Simon Neil, James Johnston and Ben Johnston – as well as touring guitarist (and solo artist in his own right) Mike Vennart to raise money for Cancer Research.

Based on the company's 1972 ’Pics Only’ amp – so-called due to the absence of any text on its front panel – the OR50 is powered by two EL34 valves, and features a traditional single channel configuration with three gain stages, an HF Drive control and a three-band EQ.

Says Vennart: “This was my amp, I toured it for about 4 years. It's signed by Simon Neil, James Johnston and Ben Johnston of Biffy Clyro, and myself. It's an absolute classic workhorse beast of an amp. Never let me down. Goddammit I miss it!”

This is the second time in the past year fans have been in with a chance to get their hands on Biffy-endorsed gear. Back in November, the Scottish trio announced the Booooom/Blast, a signature distortion pedal designed with UK builder Gone Fishing Effects.

All proceeds from the auction will go towards Cancer Research, a UK-based charity which works to help prevent cancer, diagnose it earlier, develop new treatments and optimize current treatments.

At present, the amp's bidding sits at £1,750 (approx. $2,475). To take a look or place a bid, head over to eBay.
