I use the Para EQ of my G System to shape the tone, but I would like to achieve a less gainy and warmer tone on channel 2. I'm not comfortable with the idea that I must eq the amp to get the tone I like... I know I won't get the early van halen vibe with the 5150 III, but anyway, I'd like a tone more in that direction... Also the amp has a kind of fizz around 10k that I hate... I already swapped speakers in my two 212s, and the overall tone got better, but I'd like to improve it as much as possible.There's a pretty long explanation from Howard Kaplan about why this will not work , try other 6l6 tubes or add an EQ in the loop if you want a different flavor...
