Are you talking the Afterlife? Pretty sure that runs on the Belton Brick digital unit like most reverbs from indy builders/DIYers. The BBD analog reverb chip designed in the 80s, the MN3011, was a sort of stop-gap solution, but the digital reverb tech was quickly getting better and able to be made smaller and smaller. DOD and Arion are the only other manufacturers besides Morley's Rock'n Verb I know of to make analog reverbs (the FX45 and SRV-1 respectively). Once Boss was able to make a digital unit small enough to be housed in a pedal (the RV-2, there is no RV-1), that pretty much spelled game over for analog reverb. (Fun fact, the RV-2 is the only Boss pedal without a battery clip, the reverb chip was so big they didn't have space left over for a battery.)
Apparently, the MN3011 chips are very noisy and the reverb room size is pretty small compared with even the early digital units like the Boss and the Holy Grail. Still I've been keeping my eye out for one of these older analog units because I don't mind noisy and I'm just curious if analog makes that much of a tonal difference like it does with delay.
