Documented equipment · Reconstructed order · Switchable effects loops
Premier Guitar identifies every audio effect represented here on the board filmed in late 2021. The Custom Audio Electronics controller recalls combinations of hidden loops, so the visible placement does not expose a single cable-traceable serial chain. The displayed order groups gain, modulation, looping and time effects as an editorial reconstruction; it must not be read as a verified loop-number map. Tuner, controller and power supplies are omitted.
No source publishes this sequence. The units are ordered by conventional signal-chain practice, and any documented routing zone is kept as recorded.

MethodologyQuestions about J Mascis's 2021 pedalboard
- What pedals did J Mascis use in 2021?
- This dated entry lists 15 units: Germania 44, Tone Bender Mk I / Rangemaster combo, Super-Fuzz clone, Ram's Head Big Muff, Frazz Dazzler, Double Rock, SL Drive, Real Tube Overdrive, Deluxe Electric Mistress, RetroVibe MkII, Jimi Hendrix '69 Psych Uni-Vibe, Jack Rabbit Tremolo, Lo-Fi Loop Junky, MF-104 Analog Delay, Oceans 11. This is the recorded inventory, not a claim that every connection or model identification is confirmed; see the evidence and routing notes.
- What order were J Mascis's pedals in?
- The complete order is reconstructed, not observed. The layout follows the cited routing constraints and the archive's signal-chain convention where the sources are silent. See the diagram and routing notes for the separate paths and any unconfirmed connections.
- Is this J Mascis's full guitar rig?
- No. This dated entry covers 15 units in the effects path, not every piece of gear J Mascis owned or used. Floor pedals, rack units and routing devices are included only where recorded; omitted equipment and uncertain connections are explained in the notes. It is not a complete or current rig inventory.
- When and where was this pedalboard used?
- Late 2021. Dinosaur Jr. tour rig rundown. This is one dated setup as documented, not a career-wide gear list.
- How does the archive know what was on this pedalboard?
- 2 cited sources, listed above with the date each was read, including Premier Guitar, Vintage Guitar. Among them a rig rundown and an interview. The units are recorded as documented equipment, and the page was last audited on 2026-07-18.
