  "compatibility": ["mono or stereo instrument-level input and output through the documented quarter-inch jacks","dynamic microphone input through the onboard XLR microphone preamp","5-pin MIDI In and Out\/Thru plus USB MIDI from a computer","9 V DC, center-negative, 2.1 mm power; use the manual's 500 mA rating as the conservative requirement","microSD cards of 4 GB or larger for extended loop storage"],
  "advisor": {
    "best_for": "Hands-on delay and reverb presets, live mono or stereo looping, MIDI-controlled rigs, and microphone processing where a screenless four-footswitch workflow is welcome.",
    "who_should_skip": "Skip it if you need a display-led editor workflow, battery operation, USB audio, or persistent extended loops without adding a compatible microSD card.",
    "fit_notes": "Best for players and performers who want the original DL4-style four-footswitch workflow plus modern delays, reverbs, MIDI control, microphone processing, and longer looping in a smaller chassis.",
    "watchouts": "It does not run on batteries, USB is for MIDI and supported firmware functions rather than USB audio, and a microSD card is not included. The current manual specifies 9 V DC at 500 mA center-negative; a Line 6 FAQ separately says at least 300 mA of clean 9 V DC can work. Use the included adapter or verify a third-party supply against the manual rating. Recheck each retailer's CAD price, availability, condition, and package contents.",
    "verification_questions": ["Is the included Line 6 DC-1g power supply present, or can the planned supply meet the manual's 9 V DC, 500 mA, center-negative requirement?","Does the intended workflow require mono or stereo looping, microphone input, MIDI, external footswitches, or an expression pedal?","Is a 4 GB-or-larger microSD card needed for extended and power-cycle-persistent loop storage?","Is each retailer offer still new, in stock, and available at the displayed CAD price with the stated package contents?"]

    "summary": "Line 6 DL4 MkII combines 15 MkII and 15 legacy delay models with 15 reverbs, four-switch and one-switch loopers, mono or stereo routing, an XLR microphone input with preamp, 5-pin MIDI, USB MIDI, an expression or dual-footswitch input, and 128 preset locations. Built-in looping reaches 240 seconds mono or 120 seconds stereo; a compatible microSD card expands recording time and preserves the loop across power cycles. The current manual specifies 9 V DC, 500 mA, center-negative power and recommends the included adapter, while Line 6's FAQ also says a clean 9 V supply providing at least 300 mA can work. Use the manual's 500 mA rating as the conservative compatibility target and verify any third-party pedalboard supply. This is an verified retail listing reference, not inventory stocked or fulfilled by Envoy Music; retailer prices, availability, and exact offer contents remain offer-specific.",
    "agent_summary": "Line 6 DL4 MkII is a stereo delay, reverb, and looper pedal with 30 delay models, 15 reverbs, mono or stereo looping, XLR microphone input, MIDI, USB MIDI, and optional microSD expansion. The included 9 V center-negative supply and the intended audio, control, and storage workflow should be confirmed before it is added to a rig.",
    "intent_terms": ["live stereo delay and looper","DL4 workflow upgrade","MIDI controlled delay pedal","vocal microphone looping","persistent long loop storage"],
