Voerde, Germany (August 27, 2019) -- The Lehle Little Dual II is the successor to the Lehle Little Dual and is a maximum signalfidelity amp switcher for two amps. By using the soft-touch switches you can switch between two connected amplifiers hum-free and without sound loss. The Lehle-Switches work with a microcontroller and an intelligent True-Bypass-Relay-Circuit with active pop noise suppression circuit. Thereby they switch the Lehle Little Dual II even faster than mechanical switches and in addition to that wear-and noise-free.
The centrepiece of the Lehle Little Dual II is its high-end Lehle Transformer HZ, which galvanically isolates output A from output B, making history of hum loops - permanently! Additionally the Lehle Little Dual II is equipped with a TRS switch. Therewith it is possible to send in above-mentioned stereo- or dual-mono signals via a TRS jack or “stereo-jack”.
"But using two amps is fraught with challenges: The first is that the most demanding guitarist does not want any circuitry between his guitar and his amps. This means that for the purist, active ABY switching is out of the question—thus the need for a true-bypass switcher. But switching or combining two amps using a passive ABY can often lead to tremendous hum and buzz. The BigShot ABY is unique in that it is a true-bypass switcher that incorporates an isolation transformer which may be switched into the circuit to eliminate noise when needed."
"Another concern with passive switchers is that they do not typically have any form of LED indicator to let you know which amp is active.This means that when you get on stage, you have to test your system before you play. This not only looks unprofessional, it can lead to serious problems on stage when switching between amps in the middle of a song should the artist not properly stomp on the footswitch. The new BigShot ABY solves the problem with super-bright LEDs that illuminate the instant you connect a 9VDC power supply or multi-pedal power-brick."
Designed for the purist, this compact true-bypass ABY switcher is completely passive meaning that there are no tone altering buffers in between the guitar and the amplifier. With the BigShot ABY you get the pure tone from your guitar plugged direct into your amp! To add versatility, the BigShot ABY is also equipped with a separate tuner out. This 'always on' output feeds your tuner for constant monitoring while keeping it out of the signal chain. Should you experience hum and buzz problems due to ground loops, the BigShot ABY comes to the rescue with a built-in isolation transformer and ground lift switch. Once engaged, you can toggle the polarity of the second amplifier to ensure both amps play in absolute phase.
In use, the BigShot ABY is both simple to use and efficient on stage. When powered by an external 9V supply or pedalboard power brick, full-size super-bright LEDs spring to life to provide instant on-stage amplifier status readout. When power is unavailable, the passive audio signal path still works, unaffected. The compact yet ultra-rugged design makes the BigShot ABY ideal for pedalboards where space is at a premium.
Made Radial-tough in Canada from 14-gauge steel, the BigShot ABY is supported with a 3-year transferable warranty.
