Alternative performance power from Hugo’s customised STAT-B

Hugo Sierro is a technician based in Sion (Wallis, Switzerland). He repairs guitar and bass amps, produces handmade moving coil microphones and also teaches guitar. When professional double bass player Patrick Perrier wanted some alternative performance power capability from his Schertler STAT-B pickup, he turned to Hugo for inspiration in the form of a customised pedal. Patrick wanted a pedal that could give power supply to his STAT-B (while he plays double bass) and provide two different volumes: one for rhythm and one for solos. Rising to the challenge, Hugo created the pedal as specified. Two external buttons are used to set the two volumes (rhythm and solo). The actual preamp Gain is inside the pedal. The pedal can be used with a normal 9v battery or with an external power supply. For its housing, Hugo took a BOSS DS1 pedal box and painted it in black before finally adding the Schertler sticker. This is some customisation!

Don’t try this at home! In general, we do not recommend modifying any Schertler product as this will void its warranty.

The above story is a rather exceptional example … Find out more about Hugo Sierro at
