I suppose my favorite sounds are from 70s ish Purple, Floyd, Early Fleetwood, Tull, AC/DC.
Arn't the Riff Raffs like slightly hotter mules ??
If you already have the Riff Raff, maybe you would try something else. So here are my suggestions in order :
1/ Mules is the 'safe choice' (can't go wrong with them for what you are looking for).
2/ BUT Black Dog as suggested before is a real serious alternative to consider, in the hot vintage range. They will bring you where you want, for sure.
3/ Then if you want to try something more output-wise than your Riff Raff (in order to taste something very different), my sugestion of the Crawler is not a bad call. This one is considered as one of the most versatile BKP, it does everything from blues-rock to metal. Have you listened to the demo clips ? Tim designed the AIV neck Crawler as a slighty hotter mule (7.6 DC instead of 7.3DC for the Mule). As for the bridge ? Well, Play 'the Jack' from AC/DC with the Crawler and feel the heat :twisted:
4/ Just a thought......Have you heard the Rebell Yell clip of S. Stevens ? This humbucker is one of the best classic rock sounding, less rounded and warm than the CR, somewhere in beetween the blues rock and metal you want, I expect him to be not too far away from the band you mentionned, and I suppose it will sit well in your epiphone too...
