I saw someone make a comment about how they “needed” a mid control in regards to an amp with only treble and bass controls. I’m not sure I understand where they’re coming from though. I love the simplicity of shaping my amps’ sound around the fixed mid value. In an amp with a TMB tone stack, the mids are already scooped, so I feel like a mid control would only be useful to scoop the mids even more than they already are. I’ve added a mid control to my amps a number of times, and find I always just left it all the way up. Do any of you feel a mid control is necessary in an amp with a TMB tone stack? Edit: based on some of the replies, I think it’s worth mentioning that stock Fender BF and SF tone stacks usually have a 6.8k mid resistor. I’ve heard people say this would be like having the mid control at “7,” but pot tapers don’t normally work out that 1k is 1 on the control, 2k is 2, etc. 6.8k is going to sound pretty much the same as a mid control on 10. So even though an amp doesn’t have a mid control, that doesn’t mean the amp’s mids are set to “0.” The stock value of a BF/SF tonestack mid pot is 10k.
