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. `Guitar → Seymour Duncan Twin Tube Classic → MXR Stereo Chorus → MXR Carbon Copy Analog Delay → amplifier` | # | Unit | Role | Zone | Unit evidence | Position evidence | Catalog page | | --- | --- | --- | --- | --- | --- | --- | | 1 | Seymour Duncan Twin Tube Classic | Provides McLaughlin's selectable tube gain before the modulation and delay stages. | Integrated board | Documented | Reconstructed | https://pedalboardarchive.com/pedals/seymour-duncan-twin-tube-classic/ | | 2 | MXR Stereo Chorus | Adds the broad stereo modulation McLaughlin identified in his 2010 touring effects. | Integrated board | Documented | Reconstructed | https://pedalboardarchive.com/pedals/mxr-stereo-chorus/ | | 3 | MXR Carbon Copy Analog Delay | Supplies McLaughlin's compact analog repeats after the drive and chorus stages in this reconstructed display order. | Integrated board | Documented | Reconstructed | https://pedalboardarchive.com/pedals/mxr-carbon-copy/ | ## Reconstruction note Premier Guitar's on-camera Rig Rundown identifies these three exact effects in McLaughlin's 2010 touring setup but does not publish a cable trace. The display follows the conventional gain-before-modulation-before-delay order and is therefore marked reconstructed. McLaughlin independently told Vintage Guitar that he still used the same Twin Classic option plus MXR chorus and delay in 2017; the later interview corroborates the device family but is not used to add later backup preamps to this dated board. ## Questions ### What pedals did John McLaughlin use in 2010? This dated entry lists 3 units: Seymour Duncan Twin Tube Classic, MXR Stereo Chorus, MXR Carbon Copy Analog Delay. 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 John McLaughlin'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: Guitar → Seymour Duncan Twin Tube Classic → MXR Stereo Chorus → MXR Carbon Copy Analog Delay → amplifier. ### Is this John McLaughlin's full guitar rig? No. This dated entry covers 3 units in the effects path, not every piece of gear John McLaughlin 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? 2010 tour. 2010 John McLaughlin tour. This is the rig documented for that touring period, 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.
