I need to scoop or at least shape the mids better on the Normal channel on my Super Reverb. The Normal channel has just Bass and Treble, so if I remember correctly it's like a 15k resistor to ground right? What can I do with that kind of setup to get more of a mid scoop, or shift where the mid scoop is? Until recently I've never had a need to mess with the Fender Tone Stack, but I'm trying something new out, and I desperately need to tweek the mids a bit now. Any suggestions are greatly appreciated!
