Got one of each and they're quite interesting and quite different, as outlined by Bongo's review.
The 25 has a darker sound and a "vintage" feel. Read somewhere that its sound makes you think of 70's porno flicks and from what I hear from my more knowledgeable buddies on the subject (!), it's true. No noticeable volume-loss on my unit, but the real "SURPRISE !" is that it works with a 10-volt adapter !!! (and batteries, of course). For now, i've got settings on 9.5 (range) and 3(sens).
The 25 B seems treblier (settings used: blend 7 am, sens at max and range at noon) and you can get a sound closer to an auto-wah than with the old 25. Slight Volume loss.
I still have a lot of experimenting to do (especially with the old 25). Both sound great it their own right and produce no noticeable noise.
