I hear ya. All the bass players are wondering why I haven't mentioned any mods to make the tubescreamer or boss sd-1 type of circuit better for bass players. I read the comments, and I want to help ;)
So with that said, here's a quick post-namm video on how to modify a boss SD-1 super overdrive pedal into a more bass-friendly overdrive pedal. Also, these mods will pretty much crossover into tubescreamer style circuits as well in general.
So, enjoy, have fun, don't burn yourself, and diy it 😊

Buy a new sd-1 to modify via my amazon aff link: http://amzn.to/2DU1Ez5 (yeah, yeah, I get it. But, it buys me a couple of beers and some coffee here and there. If nothing else, click the link and buy some toilet paper or somethin'. )
