Alexander Pedals · pedal
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.

Fender Vibrolux 6G11
amplifier
25% matchInto the Vibrolux's vintage tube voice, SpaceXpander's spring-style reverb layers on top of the amp's own built-in vibrato rather than fighting it.

amplifier
16% matchRun the SpaceXpander in the JTM45's loop for spring-style reverb without the amp's own tank noise.
Roland Cube Street
Roland
12% matchRun the SpaceXpander's spring reverb in the Cube Street's loop for that classic amp-reverb texture on a compact busking rig.
Supro 1605R 64 Reverb 5W 1x8 Combo
Supro
10% matchBypass the Supro's built-in spring tank and run the SpaceXpander instead for switchable spring and digital reverb modes.
Supro 1614RT Amulet 15W 1x12 Combo
Supro
10% matchThe raw, reverb-less Amulet leaves room for the SpaceXpander to add the spring and digital wash it's missing.
Peavey Classic 30 II 2-Channel 30W 1x12 Combo
Peavey
10% matchRun the SpaceXpander in the Classic 30's loop so its spring decay follows the amp's tube breakup instead of getting driven by it.

Pedals that stack with the Alexander Pedals SpaceXpander
Walrus Audio Julia
Walrus Audio
40% matchRun the Julia's vibrato before the SpaceXpander in the chain — modulating a dry, undelayed signal keeps the swirl defined.
Zvex Seek Trem
Zvex
25% matchRun the Seek Trem's sequenced, rhythmic pulse after SpaceXpander's spring-style reverb, so the tremolo chops a settled reverb tail instead of raw signal.
Death By Audio Octave Clang
Death By Audio
23% matchKeep the Octave Clang's aggressive, experimental octave fuzz ahead of SpaceXpander so the spring-voiced reverb trails a settled, saturated signal.
Paul Cochrane Timmy
Paul Cochrane
23% matchKeep the Timmy's transparent, treble-cutting drive ahead of SpaceXpander so the spring-voiced reverb trails a settled, EQ'd gain stage.
Caroline Guitar Company Somersault
Caroline Guitar Company
19% matchKeep the SpaceXpander's spring reverb after the Somersault's watery modulation, so the wash doesn't blur the pitch-shifted swirl.
MXR Flanger
MXR
14% matchRun the MXR Flanger's subtle, shimmering sweep into the SpaceXpander's bright, analog reverb and the modulation trails off in that spring-like decay.
Catalinbread Callisto MkII All-Analog Chorus
Catalinbread
13% matchRun the Callisto's analog chorus into the SpaceXpander and the modulation gets a spring-reverb tail instead of drying out at the end of the chain.
Keeley Aria
Keeley
11% matchThe Aria's compressed, mid-boosted blues drive feeds the SpaceXpander's bright, analog reverb a driven signal instead of a clean one.
