Based on the best classic boosters, the BSM Ambassador - a germanium treble/midrange booster, is a crossover between the Rangemaster Booster, the Orange Booster and the Winston Booster. The transistors are specially selected to pass the strict internal BSM factory QC guidelines. Classic boosters never cared about the midrange, and that's what makes the Ambassador stand out - the midrange and the treble range are both inside this little box. From crystal clear highs to fat and meaty mids, it's easy to dial in all these sounds with every common pickup. With the "color" control set to midrange, a singlecoil pickup really sounds like a PAF humbucker, and a PAF like fat and overwounded humbucker. The Ambassador is loaded with a special selected original NOS germanium transistor from the 60's, like the Winston Treble Booster was.
