I know of several pedals that use the MN3007 and even more arcane BBDs in that series... but does anything use an MN3006??? I may have come across some originals...
Sorry @Fingolfen I claim no authority on BBDs but just received a bunch of 3207s which turned out to be duds. Ok, I get that the odd dud is a T&C of NOS components (10-20% don’t work, I believe) but 100% is statistically improbable to put it mildly. So, to check that I hadn’t entirely lost my marbles in this regard, I swapped in a known working BL3207 and this worked fine. It’s a bit of a minefield apparently.
