New BSM Treble Booster

RPA California II Special Booster

The "RPA California II" booster is the soul-mate of our California unit, complementing it with a different goal in mind. The new RPA California II now calls for the correct pickups. The California II makes use of the free space gained via a volume pot. This allowed for the opportunity to map Blackmore's tone even with small amps.

RPA Full Quarter Booster

The "RPA Full Quarter", developed for fat single coil pickups like the "Schecter F500", the OBL 450XL (or similar) double blade humbuckers that Ritchie Blackmore used in the 1980 and beginning of the 90s. The pedal ensures no muddy or dull sound with powerful pickups like these in the operation of conventional amps to achieve a dynamic transparent sound.
