So, I adore the clean channel of my F-50 but don't need that much gain on channel 2. Read about swapping preamp tubes but I've never done it.
1. That affects channel 1, too, right?
2. Do I need to change all 4 preamp tubes or just V1?
3. Have you tried any of these? https://reverb.com/news/how-to-improve- ... tube-swaps
Thanks for your insight!
