Buy underpriced used instruments and resell after cleaning or setup to musicians and collectors.
Why that grade No centralized data source; figures are modelled from typical Reverb.com listing patterns and instrument-collector community consensus. Course-seller index 2/10.
Figures are researched estimates, not guarantees. Check local rules before you trade.
Casual sellers at garage and estate sales rarely know an instrument's true value, and reverb.com gives flippers access to a genuinely knowledgeable, higher-intent buyer base than generic marketplaces.
Underpriced garage-sale/Marketplace guitars, basses and brass bought for $50-200 commonly resell for $150-500 after a basic setup and cleaning; vintage/collectible pieces command more for buyers with real category expertise.
Someone who plays or has real knowledge of a specific instrument category (guitars, brass, keyboards) and can do a basic setup.
Anyone claiming authenticity on 'vintage' pieces without real serial-number verification skill — that's how you lose money on a fake or a franken-instrument.
Vintage/collectible instrument authentication mistakes — a mislabeled reissue, or a 'vintage' guitar with quietly replaced parts — are a real, well-documented scam category, and larger instruments (pianos, drum kits) have real transport and storage logistics challenges.
