made in Brazil
The Boosted Line Selector BL-1 was designed to give musicians three very useful options:
A/B box:Connect either two instruments to a single amplifier(with control of Level and Treble of one of the instruments) or one instrument to two amplifiers.
Booster:Boost your guitar level and "push" a tube amp, warming your tone.
Effects Loop: Create an external effects loop that can be bypassed when necessary.
