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.

The MXR M228 Dyna Comp Stereo is a stereo compressor pedal from Dunlop's MXR division, expanding the classic Dyna Comp OTA compressor to stereo output for wide, spread compression. The Dyna Comp circuit uses an OTA (Operational Transconductance Amplifier) for the classic warm, musical squish compression character associated with the original 1970s Dyna Comp. Stereo output allows dual-amp or stereo PA setups.
The Hypertonia Compressor takes its name from the medical term for excessive muscle tension, an evocative choice for a compressor pedal that likely signals a noticeably firm, squeezed compression character rather than a gentle, barely-there effect. Spermophilus Effects continues its pattern of unusual, science-adjacent naming here, applied this time to dynamics processing rather than a gain-based effect. As a compressor, its core function is evening out picking dynamics and adding sustain, though specific attack, release, and ratio behavior for this particular circuit aren't confirmed from available sources.
