  "advisor": {
    "best_for": "Players who want one always-on box at the front or end of the board that does three jobs: a boost\/preamp voiced after the Roland RE-150 Space Echo preamp (via Mile End's Preamp 150 circuit), a high-headroom buffer, and switchable harmonic enhancement. Especially suited to tape-echo-preamp tone chasers and to anyone who wants a set-and-forget tone conditioner rather than another gain pedal — with all four switches off it works as a standalone buffer.",
    "who_should_skip": "Anyone wanting fine-grained tone control: shaping is done with four fixed-voice rocker switches (Boost, Brilliance, High Freq, Low Freq) plus a single Level knob — there is no variable gain or sweepable EQ. Also skip it if your power supply is maxed out: at 250 mA it draws far more than a typical boost or buffer, and many isolated supply outputs rated at ~100 mA per tap won't run it.",
    "fit_notes": "Needs a 9V DC centre-negative supply output rated for at least 250 mA — check your supply's per-output rating before adding it to a full board. The three voicing switches divide the spectrum deliberately: High Freq adds 1.6 kHz op-amp saturation to upper frequencies only, Brilliance is a bright-cap-style filter that trims low end and pushes mids\/highs, and Low Freq is a phase-shifted low-pass filter that adds saturation\/compression to the lows — so you can enhance highs and fatten lows independently. Handcrafted in Montréal with a lifetime warranty, so a repair path exists for the life of the pedal.",
    "watchouts": "The footswitch disengages the buffer when the pedal is off — bypassed, it is not buffering your line, so don't count on it to drive long cable runs while switched off. The 250 mA current draw is the most common integration snag; a shared daisy-chain or low-rated isolated tap may brown it out. Verified dimensions and weight were not available from our sources, so confirm enclosure size if your board space is tight.",
    "verification_questions": ["What voltage, polarity, and current does this exact revision require?","Are the original box, power supply, and any model-specific accessories included?","Does this listing match the exact revision and finish shown in the source photos?","Is the item still in stock at the displayed price, and what is the complete delivered cost to the intended destination?"]
