Based on recommendations at TalkBass & a Labor Day sale via Reverb, I picked up the BETA Mk II Germanium pedal from SolidGoldFX to try and recreate the sound I got with my overdriven F-2B. It was just delivered Monday, I like it so far - it gives a definite bass-boost that isn't controllable - for that you need the BETA DLX which offers a bunch of different options, but is also much bigger. I re-recorded my demo piece with the BETA, it sounds different than my F-2B one (the drums & the bass) but it should give an idea of what the BETA does.
I used a different bass on this one - my Fender Donald Duck Dunn P-Bass (passive) with heavy LaBella flatwounds (that I won in a contest!) but it's a similar sound to what I was going for with my AlFemBic - to make comparison easier here's the original demo:
