# J Mascis Pedalboard 2021: Full Gear & Pedal List > The 2021 J Mascis pedalboard, pedal by pedal: Germania 44, Tone Bender Mk I / Rangemaster combo and 13 more. Signal-chain order, settings and cited sources. - Canonical page: https://pedalboardarchive.com/artists/j-mascis/dinosaur-jr-touring-board-2021/ - Machine-readable index of the archive: https://pedalboardarchive.com/llms.txt - Evidence and reconstruction conventions: https://pedalboardarchive.com/methodology/ ## At a glance | Field | Value | | --- | --- | | Artist | J Mascis | | Board | Bradshaw-switched touring board | | Date | 2021-11-01 — Late 2021 (era precision) | | Context | Dinosaur Jr. tour rig rundown | | Scope | Exact board snapshot | | Signal path | 15 units · Guitar to amplifier | | Routing | Switchable effects loops | | Unit evidence | Documented | | Order evidence | Reconstructed | | Status | Photographed inventory · loop order reconstructed | | Audited | 2026-07-18 | | Sources | 2 | J Mascis's late-2021 Dinosaur Jr. board is a Bradshaw-switched wall of fuzz: a Tone Bender Mk I, a Super-Fuzz clone, a Ram's Head Big Muff and a Frazz Dazzler, plus a Deluxe Electric Mistress, two Uni-Vibes, an MF-104 analog delay and an Oceans 11. ## Signal chain **Order evidence — Reconstructed.** No source publishes this sequence; the order is reconstructed. The units are evidenced; their sequence is the archive's inference from the convention below, not an observation. Do not report this order as documented. Reconstruction convention: Tuner → Wah and filter → Compressor → Overdrive, distortion and fuzz → Modulation → Delay → Reverb → Amplifier. A documented routing zone always overrides it. | # | Unit | Role | Zone | Unit evidence | Position evidence | Catalog page | | --- | --- | --- | --- | --- | --- | --- | | 1 | Germania 44 | Pushes selected drive and amplifier combinations with a bright germanium boost. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/germania-44/ | | 2 | Tone Bender Mk I / Rangemaster combo | Supplies two vintage gain colors inside the switcher's long-running core. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/tone-bender-mk-i-rangemaster-combo/ | | 3 | Super-Fuzz clone | Provides the aggressive upper-octave fuzz voice among Mascis's switchable gain options. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/super-fuzz-clone/ | | 4 | Ram's Head Big Muff | Delivers the sustained, saturated lead voice at the center of his live sound. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/ram-s-head-big-muff/ | | 5 | Frazz Dazzler | Adds a modern gated and highly saturated fuzz texture. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/frazz-dazzler/ | | 6 | Double Rock | Offers lower-gain rhythm drive and stacked boost alternatives to the fuzz pedals. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/double-rock/ | | 7 | SL Drive | Provides a compact medium-gain amplifier voice in the switcher's drive bank. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/sl-drive/ | | 8 | Real Tube Overdrive | Supplies a smoother tube-driven gain stage distinct from the board's fuzz voices. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/real-tube-overdrive/ | | 9 | Deluxe Electric Mistress | Adds metallic sweep and fixed filter textures after the gain section. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/deluxe-electric-mistress/ | | 10 | RetroVibe MkII | Adds deep optical pulse and pitch movement as a modern vibe option. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/retrovibe-mkii/ | | 11 | Jimi Hendrix '69 Psych Uni-Vibe | Provides a second, compact optical-vibe flavor on the late-2021 board. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/uni-vibe/ | | 12 | Jack Rabbit Tremolo | Creates rhythmic amplitude pulses with a separate modern tremolo voice. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/jack-rabbit-tremolo/ | | 13 | Lo-Fi Loop Junky | Adds short, unstable backing loops and degraded texture within the switched system. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/lo-fi-loop-junky/ | | 14 | MF-104 Analog Delay | Provides dark analog repeats and modulated delay textures. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/mf-104-analog-delay/ | | 15 | Oceans 11 | Adds selectable ambient and spring-style reverb at the time-effects end of the system. | Switching loop | Documented | Reconstructed | https://pedalboardarchive.com/pedals/oceans-11/ | ## Reconstruction note 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. ## Questions ### 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. ## Sources 2 cited sources across 2 independent groups. Two sources sharing an independent group report the same observation and count once. 1.
