I've noticed while going through my own personal dirt pedal question that almost without fail I really enjoy the tones and capabilities that come from pedals that have either voltage sag/starve controls in their circuit, or bias controls. I know there are examples that are excellent for bass, like the Fairfield Barbershop (sag control), Heavy Electronics Grind Fuzz (sag control) and also ones that are less ideal for bass, like the Germanium Big Muff (voltage AND bias controls!). I'm also guessing though that there are a lot of others out there I've not come across yet. I think the ss/bs TAFM also has a sag feature too. Can people suggest/list dirt pedals with these kinds of controls available on them? (Yes, I am aware that you can get a sag control built into a separate pedal, or that some pedal power devices have the feature too, but at this point I'm just curious about circuits where it is inherent to the pedal.) Thanks!
