What kind of music are you playing? Overdrive/distortion/fuzz are very common, but if it isn't right for your music, then it's the wrong call.
Your first two pedals are spectacular choices (I own both

), and apparently you have a taste for quality stuff (YAY!).
The choices from this point are numerous, and the best thing you can do is to start listening to as many samples of - or better yet, test for yourself - the kinds of pedals you're interested in. When you hear something that grabs you by the throat, kill it (aka: buy it) and drag it back to your cave.
OD/dist/fuzz are very personal tastes. What sounds fantastic for one person, may sound like crap to somone else. A few well-loved effects in the "dirt" family, by TB'ers, are:
- EHX Little Big Muff
- EHX English Muff'n
- Fulltone Bass-Drive
- Malekko B:assmaster
- BJF Blueberry
(I know I'm forgetting a few great ones)
A couple more of my favorites are:
- Prescription Electronics Depth Charge
- Fulltone OCD
Happy hunting!
