Peavey classic 50

Hey guys , I recently picked up a Peavey classic 50....I have an et65 Id like to drop into the cab any rec. for the other speaker? i prefer a smooth somewhat dark buttery singing sound like Carlos..Peter Green etc. i play lots of single note solo melodic lines...and use several pedals in the effects loop , so it still needs to get loud and remain clean and clear if not using the drive channel the stock blue marvels crap out when pushed....I have a 50'w valveking that sounds noticeably better with the et65 , its a single speaker model though..thanks..

I play a les paul w humbuckers and a yamaha sbg w humbuckets...usually neck pick up
