This took ages to find and I,m not sure how to post a link but if you look in 'amps and cabinets' on page 64 and look at page 6 of 'what,s in your rack' you,ll find it.
If anyone knows how to move this to the build diary to find it easier please do, as I type this I,m in the process of updating the rig and will post the new pics when it,s finished.
