Expanse Series

The Expanse Series by Neunaber Audio is a versatile and programmable stompbox that offers multiple reverb and modulation effects. It can be used to provide reverb, echo, shimmer, and chorus effects, among others. The pedal is designed to be placed at the end of the signal chain, after other effects, and is recommended for use in the effects loop when using the overdrive channel of an amplifier for optimal results.

The pedal features various input and output jacks, a USB jack for connection to a computer, an ExP port for an optional ExP controller, and a footswitch for bypassing the effect. It also offers three selectable bypass options: buffered trails, true bypass, and two-stage trails/true bypass.

The Expanse Series pedal can be programmed using the Expanse software, which allows users to load different effects and configure the mix knob and switch behavior. It also supports the use of an optional ExP controller for accessing additional functionality, including four effects, two presets for each effect, three expression inputs, and a Preset Morph expression input.
