I have recently switched from guitar to bass, and would like to build pedals specific to the bass. After playing my first bass gig in the French Quarter last weekend, I realized I need a good compressor that has attack and decay controls, and most importantly, a blend control to keep the low frequencies intact and clean. I need something to limit the volume on the loud notes in order to preserve the structural integrity of the old architecture. 
An example of what I would like to build is the new MXR "Bass Compressor M87." The new LED on the M87 is cool, but not necessary. I will likely end up buying this pedal, like the MXR M-80 I bought last week, but I'd also like to build this pedal.
I also like the MXR "Bass Octave Deluxe M288" and the "Bass Envelope Filter M82," as both of these pedals not only sound great, but they are very versatile and have a small footprint. These are GAS pedals, so I will likely not buy them, but rather build them instead.
Fuzz/Distortion/OD pedals can be made using several existing Madbean projects, though it would be nice if all the project pages included the bass mods explicitly (some already do, thanks Brian).
