NOS (new, old stock) Custom Micro Bloom.
Only 3.6" x 1.5". Point-to-point wiring. Deluxe finish.
Just three of these tiny custom Algal Blooms were made about a year ago. This one has been hanging around the shop since then (it was set aside for a component replacement and time got away), but is now 100%, and sounds great. 
Not the current AB Modified version--this was custom spec'd between versions (having elements of the AB v3 and AB Mod). 
Controls: Bloom (overdrive), Bias, Headroom, Level
