i havent replaced the tubes in my marshall tsl that came with it when i bought it, and ive seen a lot of talk about new tubes recently on here. Ide really like to get a more heavier sound out of this amp, or atleast more gain. i love the lush marshall tone tho also. I dont have the money or the need to go buy a new head, vht, bogner, mesa whatever, but i can spend some money on tubies no problem. so if you guys have any suggestions for what brand/type of tube would give me the heaviest possible sound, and what brand would give me the best tone, then i'll just try them both and see if i have to sacrifice tone or gain for the sound i like more. it would be really nice to just have them both tho
thnx for the help

I really like JJ e34Ls in the jcm2000 series also the jj preamp tubes will give you a little darker distortion eh makes some great ones as well all up to taste on preamp tubes.

Effects - MXR phase 90,BOSS DD6 , BOSS BF2

Chinese 9th Generation 12ax7s. They aren't as dark as the JJs, and have more gain.

I do agree about JJ E34Ls. I'm a firm believer in JJ tubes, and the E34L is one of the best tubes IMO. In case you don't know, they have the low end grunt of a 6L6, and the mids and highs of an EL34.
