Tubes: 6L6's Vs. EL34's

Can anyone tell me the tonal qualities of 6L6'S and EL34'S. My Marshall has 5881's which I believe to be 6L6's. To me, it's very muddy. Would EL34's tighten up the sound?

I agree with your assessment of 5881 power tubes. A look at this Eurotubes page can help with the rest.

I have a Peavey XXX head that came stock with 6L6 power tubes, and changed them out for some JJ EL34's. The EL34's gave it a more aggressive, tight, in your face distortion, and the clean is more punchy. 6L6's are a bit warmer tone wise than EL34's. Personally I love the more aggressive tone of the EL34's. You should be able to find all the info on tubes you need at eurotubes like LOTS said. That's where I buy my tubes from. Bob is a great guy to deal with.

Thanks for the helpful info everyone.........I think I'm gonna change to EL34's, at least to give them a try. Gotta tighten up the 'ol tone.
