The Korena take
StereoMaker is a stereo-emulator and phaser pedal for routing one input to two outputs while adding an analog spatial effect. Width and volume controls let you set the stereo spread and output level. Its 180-degree polarity reverse circuit addresses phase mismatches in dual-amp setups, while buffered, transformer-isolated outputs and a ground lift support more involved rigs. The PAD switch accommodates line-level signals, making it relevant to keyboard and synth connections as well as guitar setups.
Strong match
Who this is for
- Splitting one instrument signal to two amps while correcting an out-of-phase dual-amp setup.
- Connecting line-level keyboards or synths through the PAD switch in a stage or studio rig.
- Sending a stereo-style signal that can fold back to mono without unwanted side effects.
