## Tools (7)

- `check_board`: Check a set of pedals as a pedalboard: a suggested signal-chain order with reasons, total current draw against a power supply, and a count of power and compatibility issues.
- `compare_pedals`: Two to five pedals side by side: score, what each is best for, lowest new price, used median and key specs.
- `get_guide`: One buying guide: who it is for, what matters when choosing, the three picks (best overall, budget, step up) with strengths, flaws and current prices, and the other pedals considered.
- `get_pedal`: Everything PedalBro knows about one pedal: specs (power, size, bypass, controls), a plain-language summary, the PedalBro review score, what players say, professional review ratings with links, current new and used prices with buy links, and similar pedals.
- `get_price_history`: How a pedal's new and used prices have moved over the last 90 days (weekly points), recent sold used listings, and current prices. Useful for 'is this a good price' and 'should I buy used'.
- `list_guides`: PedalBro's buying guides ('best overdrive pedals', 'best delay under $200', ...), each with its top pick. Use get_guide for the full picks.
- `search_pedals`: Search guitar and bass pedals by brand, model, nickname or type (typos are fine), optionally only those buyable new under a price. Returns names, slugs and lowest new prices.
