I own a splawn superstock which is built to sound like a modded marshall plexi/jcm 800

it use four 12ax7 and four el34s, its finally time to retube it

i know that i want my amp to sound darker and to have more gain, according to the ultimate tube thread the JJ sounds exactly what im looking for. are there any tubes in the same price range that will do the same thing as the jj's just better?

07 Fender American Deluxe Strat
07 Fender Custom Telecaster
09 Seymour Duncan Pickup Booster
09 Fulltone OCD V.4
10 Ibanez WH-10 V.2
09 Splawn SuperStock
10 Jet City JCA-20
97 Fender Hot Rod Deluxe

Yeh the SICK! bit sounds a bit stupid.

Probably not, most tubes come from one of three or four factories so real variation is hard to come by. Besides, you can get JJ's for fairly good prices depending on where you buy them from, mind you it's been a while since I last time looked at tubes.
