In 1966, Eric Clapton established the quintessential sound of Rock Guitar.

With his Marshall "Bluesbreaker" 2x12 combo amplifier and Gibson Les Paul in hand, he recorded what is often regarded as the greatest guitar tone of all time.

The "Beano Album"--Blues Breakers, John Mayall with Eric Clapton--set the benchmark, by which all future Rock Guitar tone would be judged.

There was however, one vital, yet almost secret component to this legendary tone, which was too often overlooked.

The "Bluesbreaker-Pinstripe" grill cloth, unique to Marshall Amplifiers from 1965-1968.

Used across the entire Marshall range, this distinctive cloth was mounted horizontally on the combo amps and often referred to as "Bluesbreaker" cloth.

When mounted vertically on 4x12 and 8x10 speaker cabinets, it was commonly  called "Pinstripe" cloth.

Unfortunately, this legendary "TONE CLOTH" disappeared from production in early 1968 and would remain extinct for the next 40 years...

     "Then, in February 2006, Eric (EC) Collins started a quest that was to take him three years to complete and set himself the mighty task of recreating the cloth that was the gold standard of vintage Marshalls. The highest compliment is Marshall's use of the Collins cloth on their 50th Anniversary Bluesbreaker reissue from 2012."
