Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.46% — somewhat different

The Alexander Pedals SpaceXpander is a discontinued three-mode digital reverb from Alexander's early catalog with a silent footswitch and buffered bypass with optional trails mode. Three modes: SPRING (adjustable tone and virtual tank size), PLATE (with pre-delay and damping producing tails up to 25 seconds), and ANALOG (emulating the Panasonic MN3011 six-tap multi-tap BBD chip to produce an unusual rhythmically percussive reverb character). The Space knob on Analog mode slides from reverb-length to delay-length tails. Available only used.
The Keeley Vibe-O-Verb is an ambient reverb pedal with modulation built directly into its reverb engine, housed in an all-metal chassis with depth, rate, blend, and decay controls. A three-mode switch shapes the modulated reverb voice: Harmonic mode adds vintage tremolo-tinged shimmer, Vibrato mode gives a chorus-y spaced-out wash, and Phaser mode morphs the trails with sweeping movement. Its base is a sparkly, spacious reverb that suits country and rockabilly while scaling to large ambient soundscapes. Reverb times are calibrated using the Golden Ratio to stay musical and avoid disorderly noise. True bypass keeps the dry signal uncolored when off. Lower rate with depth at noon yields dreamy movement without the modulation overpowering the dry tone.
