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.45% — 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 Electro-Harmonix Holy Grail Max expands on the original two-mode Holy Grail reverb with four voices: Room and Hall for natural, spacious ambience, Spring for the boingy, splashy character of a real spring tank, and Flerb, a flanged-reverb hybrid that adds a swirling, metallic modulation on top of the reverb trail for more unusual, textured ambient sounds. A simple Reverb mix knob and mode selector keep it easy to dial in despite the added versatility. It carries forward the same accurate, musical core voicing that made the original Holy Grail one of the most popular reverb pedals ever made, while adding real range beyond straightforward room and hall ambience.
