"I’d spent some time upgrading my Blues Junior mk2 with better-spec components; larger pine cab, Cannabis rex, caps & resistors. What difference could alternative preamp tubes make? Well…I’ve already thanked Stewart for hooking me up with these beauties. 7025’s in the V1 & 2 sockets really have cut background noise to pretty-much nowt & any ‘loss of gain’ (I use pedals for this anyhow) is made up for by being able to play at increased vol & greater clean headroom. I lik’em & you might too!." - MH bought EH 7025's and reviewed on 18th July 2021
