This is the Sobbat DB-3. Recently, Funk Ojisan on YouTube featured the Sobbat DB-2, and this is the successor to that pedal. It seems to be designed for humbuckers, but it thickens up the low end quite a bit in situations where Strats and Teles sound thin, so I think it works well with single coils too. Sound-wise, it doesn't do a pure clean sound, but it can go from a subtle overdrive to a gritty (with some noise) distortion. The boost circuit only works when the main circuit is on. It's a Japanese-made effects pedal that you don't see very often anymore, but it's still a quality pedal that's perfectly usable today. No box or accessories are included. Thank you.
