I just drew up a vero layout for the sansamp BBDI 'lite' vero ('lite', standing for no XLR out). I haven't built it yet so it's not verified yet, but I think that I got everything correct. it's pretty huge at 35 x 20 but it has to go into a 1590BB anyway since it has 6 pots (and I may later add two switches for the scooped mids issue that they're known for).
Yes, if you want to change earth rotations with your bass driven sounds, you need to have those mids back! Im talking as a bassplayer too, my guitar playing is more oriented to house recording and those things,
Thanks for the layout, and curious to see the mods!
after quite a bit of experimentation I finally got it to sound ALOT better.
IMO, the stock BBDI and BDI21 pedals are way too scooped, especially with the twin filtered overdrive circuit. and having a 'presence just exacerbates it. I removed the first OD filter completely, turned the OD's pre boost presence control into a pre-gain mids control, gave it more gain (on the OD side), and filtered out a lot of the distortion's fizzy top end. this circuit basically clips an opamp which is not my favorite way to achieve dirt, but these changes made it ALOT of usuable for me and it actually sounds really good to me now.
i'm also using a TLC2264 in both opamp positions since I think that they sound better and smoother.
