tube help for dual rectifier 3 channel

[dropped_2_c]

I haven't been on here in a few years so i had to make a new account. nevertheless I currently have jj6l6GC's in the power section a ruby 12ax7c( i did have a tung-sol but i didn't like it it just had a quality that made me feel like the gain was not as heavy or alive) v2 a jj high gain, in v3 v4v5 chinese 9th gen including the matched pi tube.

Now i also have 5 mesa labeled 12ax7r's and a GT 12ax7r.

THE PROBLEM, i feel the amp is Dark sounding( I am blaming the jj's on this one) I use a vin 30 cab, a vin 30 and cl80 x pattern cab as well. i just dislike the dark not bright sound, i can dial the treble on ten and presence and compared to other amps it still sounds really dark and mids are at noon as well. i don't run the treb and pres. on 10 just making a note of what i have done to find the problem.

I play ozzy and death metal so i am wanting it to be tight but yet gainy and cut still bright sounding. think cannibal corpse but thick, ozzy etc

I have thought about pulling out the jj power tubes and putting in =C='s 6l6 and replacing maybe v2( the jj) and maybe v1 what can get me to the earth shattering high gain realm of massive but yet killer tone. i am lost here just looking for suggestions the 12ax7's ( boogie) i took out were used maybe an hour or 2 before i got the tubes from Doug's TUbes last year

I agree. With all of the hype given to JJ's around here, I decided to give them a try in my DR in both the preamp and power amp section. I thought it left my amp feeling dull and lifeless, especially in channel 1.

Maybe it was just because I was used to the stock tubes for so long, but after having the JJ's in there for over a year now and hearing how great my Roadster sounds with the stock Mesa tubes, it might be time to go back to the Mesa tubes in my DR as well.

If you pull the JJ try running the chinese tubes in the tone circuit positions. The chinese tubes tend to be bright. I have heard that the JJ 6L6's are not exactly bright either. It si hard to have both bright and thick in preamp tubes. You might try a Tungsram (Hungarian) 12ax7. I remember those being thick sounding. Also your other qulaity NOS tubes like Mullard, Telefunken, Amperex, etc., will have a thicker sound. If I remember correctly Bugle Boys were rather bright for being lush. I like Phillips, Sylvania's, GE's, and RCA's too. Those Mesas and the GT should all be brighter than the JJ. Just remember that the amp sounds different as you turn it up too. These amps were made to be played loud.
