I have been interested in how Mr. Page got some of his early sounds for a while now. Over the years I've read as much as I can find on the subject and I know he has not specifically revealed many of his secrets. It seems obvious he did use a small amp on many of his early songs. It sounds small, but is engineered very well into the mix as they say. I've tried a few old Silvertones, Airlines and the likes over the years and some of them sound cool but just seem to small and not jangley enough. These are as close as I can get to a vintage Valco here in Texas without paying up. So I have been trying different things to see if I can get the "jangle" ( best term I can come up with at the moment) that is in Houses of the Holy. I've been using my Univalve multi tube capable amp to try out some weird configurations. Today I tried 2-12aty's as the preamp drivers into an old KT88. For speakers I used some old Webers but changed the result into something that fit the sound I was looking for a bit better. I think this is close but this profile is the most sensitive I have made to the guitar used and the cab selected. I always though he might have used a slightly cocked was on this song or some pair of pickups out of phase but this profile has that sound without that. To me and the guitar I am using its close. This profile is probably not that usable but its fun to use on old Zeppelin. Its labeled Univalve - Holy House.
I also put up some H&K switchblade profiles. Its a cool amp and I'm still playing around with it.
