Ok, so sat at practice last night with the cream pie, bbbod, angler and SFT on a pt nano, it was a very very cool but point less board
Now I never tried the original BBBOD so I can't really comment how close they are. I'm just putting my thoughts out there on the bbbod as a new pedal.
Firstly, to me this is not low gain, not even close, with the nature and gain at zero it sounded very fuzz like to me, don't get me wrong a very nice dark fuzz and a sound I've never really gotten before but a Cream Pie it is not. There is no slightly gritty sound to me. It's a great gain sound with no low end loss and only compresses badly with an active with the gain cranked.
By far of the 3 od pedals the SFT is my fav with the cream pie (bearing in mind I never owned one with my current amp Matamp GT200) that really falls into dirty boost at best with me haing to use the volume to get gritty sounds over the gain.
So if I break it down
BBBOD vs CPD. If you were after a low gain tube with slightly gritty sound the CPD is the only way to go. The BBBOD is like buying a fuzz pedal to get this tone. just not going to happen or go get a Dod 250.
BBBOD vs SFT. SFT is capable of a bigger low end and a zingier high end with everything in between. Gain similar though they both nail bass distortion tones that make me want to groove and not riff like I'm a guitarist (if that makes sense)
BBBOD vs Angler. So different it's not even real, if you like one it's unlikely you'll like the other thou you could have them on the same board to do completely different sounds but they really do cover different ground and have very different characters.
What I'll be doing later today is pitting the BBBOD against my fuzz pedals and seeing where it sits, I do like it tonally but it's not low gain enough for my preferences, I have a chance to buy a Dark Driving which I may go for if that's the same character but capable of lower gain sounds.
Have to say I was very surprised at how much I liked the Angler, really cool pedal.
Will also try doing some clips tonight on my iPad with GarageBand so can't promise anything will sound good.
