The Twinline is an effects loop router that may be remotely switched to follow the active amplifier in an advanced stage setup. This enables the pedalboard or effects rack to utilize the two amplifier rear-panel effects loops while sharing the same effects. The circuit design is optimized to work from -30dB to +10dB, providing plenty of range for both guitar pedals and professional studio effects while introducing minimal artefact.
