Verifier × model pass rate

How often each verifier passed, per model. Green is passing, red is failing — a red band across a row is a verifier nothing clears.

How to pass

Research currently available electric guitars suitable for both rock and blues, using reputable retailers and manufacturer information. Record the exact model, configuration, current price, availability, and finish/shape. Do not treat a generic model listing as sufficient when the task requires a particular exotic finish. Verify that the specific guitar variant satisfies the user's maximum $500 USD budget and is actually purchasable when researched.

How to pass

From the researched guitars, identify models priced at $500 USD or less that also have an unusually distinctive color, finish, body shape, or stage-oriented visual design. Verify the exact finish/variant and price rather than assuming that every color of a model costs the same. Preserve the purchase currency and date checked. A guitar qualifies only if both the price and the requested visual characteristic are verified.

How to pass

Select exactly five qualifying guitar variants. For each, provide the exact model and finish, current price, availability, manufacturer/retailer evidence, and a purchase link that leads to the specific qualifying finish or variant, not merely the model's generic product page. Briefly explain its suitability for rock and blues based on documented pickup configuration, construction, controls, or credible reviews. Do not rank guitars solely by popularity.

How to pass

Provide an accessible image or image-search result for each of the five specific guitar variants selected in Step 3, ensuring the image corresponds to the stated finish and model. Do not require opening a new browser tab; instead, make the images directly accessible in the research output. Do not use an image of a different finish as evidence for the qualifying product.

How to pass

Research how electric-guitar string gauge affects tension, feel, attack, sustain, tuning stability, and perceived/heavier tone. Compare appropriate gauge options for the selected guitars, considering scale length, tuning, pickup configuration, playing style, and the guitar manufacturer's specifications where available. Explain that heavier strings can provide greater tension and a different feel but do not automatically produce a universally “heavier” sound; amplifier settings, pickups, tuning, picking technique, and setup also materially affect the result. Recommend a practical string gauge for the selected guitars and identify any setup or intonation considerations when substantially changing gauge.

How to pass

Create a concise document containing the five selected guitar models and exact finishes, current prices and availability, qualifying purchase links, evidence supporting rock/blues suitability, and accessible images. Include the recommended string gauge for each guitar or a clearly justified common gauge where appropriate, followed by an explanation of how string gauge affects tension, feel, attack, and tone. Clearly distinguish verified current retailer/manufacturer information from recommendations or judgments. Do not purchase anything.
