I have to replace the output tubes in my Rivera Knucklehead Reverb.
Stock they have the winged C's. The problem is i need tubes fast and my supplier hasnt any in stock. But he does have a matched quartet of JJ 6L6GC's. I dont have and experience with these, can anyone tell me what i can expect in terms of sound, output etc between the two please.

Cheers.

Sweeter tone, kinda dark not as good of low end. I knowsome prefer the JJ. I like the Svetlanas.

JJ's sound more 'wide open' and Svets sound more compressed and round. JJ's sound really good when you want ultimate punch. Svets are better if you want a softer feel under your fingers.

Good to hear, i'll give the JJ's a go and see what happens.

Cheers for the input.
