I loaned my #1 633 amp, a Custom 36, to maker Cliff Brown for photography and review in Guitarist magazine, which was published in the August 2016 issue.
The amps were with them for quite a long time and word filtered back that they were really enjoying them and weren’t in a hurry to return them. Fortunately, my #2 arrived during #1’s absence so I could get to know that too.
This is borne out by the fantastic review. Forgive me if I quote : “..the Custom 36’s owner-driven spec hits the performance and sonic bullseye for us – it’s simply the best amp of its type we’ve ever plugged into…”.
NB the amp was rehoused in a rather more universally-appealing black and wood cab for the review and they didn’t even have my matched cabs, one with an Eminence Red Guv’nor and one with a Celestion G12-75 Creamback….
