[QUOTE="muudrock, post: 91068, member: 29"] Got it set to 1/2 the actual cab impedance? What output tubes? What speakers? These things will have a bigger impact on perceived bright/darkness of the sound than any preamp tube ever will. JJ's in my experience aren't "darker", but a little smoother than say an EH or a Sovtek. The most neutral tube I've found for the PI is the Sovtek although like others have said, the JAN 5751 sound good to with lower input gain. Tung Sol seem to have an upper mid bump. The PI is one of the hardest working tubes in a tube amp so don't skimp on quality there. [/QUOTE]
