Musos Corner is proud to be an authorised retailer and highly recommends Boss musical products. The first Boss guitar effects pedal was released in 1976, the CE1 Chorus Ensemble and contained the chorus / vibrato unit from the famous JC120 Jazz Chorus amplifier. Vintage Boss pedals are now very collectable and can command some unrealistic figures. Today the Boss ethos of reliability and innovation continues to make it a very popular choice for effect pedals and amplifiers. Boss products are built tough for everyday use regardless of the application and Musos Corner is an authorised service agent for the entire catalogue.
