We built Tonechaser because the things that matter most to a musician — your gear, the tones you fight to dial in, and the deals you make to get the next piece — never lived in one place. Now they do. CATALOG EVERY PIECE OF GEAR Track every guitar, pedal, amp, mic, and cable you own — 22 gear types, each with the specs that actually matter, plus photos, price, condition, year, and serial number. • Add gear by hand, or just talk — dictate several pieces at once and let Tonechaser sort them out • Unlimited photos per item, backed by a 4,000-brand database so you're not typing manufacturer names • Insights: see what your whole collection is worth, with median prices and where values are heading • Full backup and export — your inventory is always yours REMEMBER HOW YOU GOT THE SOUND Stop guessing how you nailed it last time. Build a tone as a real signal chain — guitar into pedals into amp — and keep the notes, photos, and recordings that prove how it sounded. • Build the chain by tapping, or by voice: say your rig out loud and Tonechaser matches it to gear you already own • Artist Rigs: tap through how well-known players built their sound KEEP THE RIFF WITH THE RIG Record straight from your iPhone and keep the sound with the gear that made it. • Record or import audio and video, tag it, trim it, and attach it to a tone • Tap Track: tap a beat on your chest or a table and Tonechaser turns it into a looping drum track timed to how you played — then stack more parts on top BUY AND SELL WITH REAL PLAYERS — BACKSTAGE When it's time to move gear, you're dealing with other musicians, not a faceless listing. • Browse thousands of listings from retailers and other players; filter by type, price, condition, and location • List in one tap from your inventory — your specs and photos are already there • Make offers and message the seller directly on players' listings; counter, accept, or walk away • Build a wishlist and get told the moment a match shows up • Read and write real gear reviews — with audio and video — and ask questions before you buy • Sellers keep 100%. Tonechaser never touches the sale. Cataloging your gear, building tones, and recording clips are free, forever. Backstage — the buying and selling — is $49.99/year with a free trial, and you only reach it when you actually make an offer, list gear, or message a seller. Because Tonechaser already knows what you own and how you use it, listing a piece takes seconds — and your whole rig finally lives in one place instead of six.
