EHX still do use the 3008 & 3005 but on a, when we can't source them, that's it basis, which shows that it's only worth it to them to use what little remains than spend a fortune making new ones (which i'm sure people would say weren't as good as the originals anyway) through hole production is on the way out as it is so I think it's just too late as the equipment needed to make such a thing is phased out, plausible I suppose that some kind of SMD BBD could be produced but I doubt it, all this stuff (BBD, PT2399) came about mainly due to the japanese karaoke machine industry along with a few other products and I suspect they are moving in to the digital age as is the rest of the industry, pedals and especially DIY are a much smaller market than you'd expect. I think the only other company to produce BBDs other than cool audio is I think (don't hold me to this) MXR who produce an MN3204 clone and they're a pretty large company. I'd take what you can get while it's still here personally! Or buy one of the closing through hole factories.
