The tab problem
Every musician who's shopped for used gear knows the drill. You want a Fender Telecaster in good condition, so you open Reverb. Then eBay. Then Facebook Marketplace. Maybe Guitar Center's used page. You're ten tabs deep before you've compared a single price.
By the time you find something promising, you've forgotten what you saw three tabs ago. Was the sunburst on Reverb the one with the neck crack, or was that the eBay listing? Did Guitar Center's price include shipping? You screenshot things. You bookmark them. You text links to your bandmate. It's a mess.
This is the part of buying used gear that nobody enjoys. The playing comes later — the shopping is homework.
What comparison shopping should feel like
Imagine typing "left-handed Telecaster under $800, excellent condition" and getting results from every major marketplace in one place. Sorted, filtered, price-compared. No tabs. No mental spreadsheet. Just the best options, ranked.
That's what Treblemakers does. One search, every source.
Our AI understands natural language queries, so you don't have to learn each marketplace's filter system. Behind the scenes we're querying APIs, crawling inventory, and normalizing everything into a single, clean results page. You see the listing, the price, where it's from, and whether it's a good deal — all without leaving the site.
Why "used" matters
New instruments are straightforward — walk into a store, pick one up, pay MSRP. Used gear is where it gets interesting:
- Price variance is massive. The same guitar can be $400 on one platform and $650 on another. Condition descriptions are subjective. Shipping costs vary wildly.
- Deals disappear fast. A great used instrument at a fair price doesn't sit for weeks. If you're not watching every platform, you'll miss it.
- The market is fragmented. Reverb owns the musician niche, eBay has the volume, and hundreds of indie shops have hidden gems that never appear in either place.
Nobody has built the aggregation layer for this market. We think that's a mistake worth fixing.

Built by a musician, for musicians
I've spent more hours than I'd like to admit refreshing eBay searches and comparing prices on Reverb. The idea for Treblemakers came from frustration — I knew the gear I wanted existed at a fair price somewhere, but finding it felt like a second job.
So we built the tool I wished I had. If you've ever lost a deal because you weren't watching the right platform, or overpaid because you didn't know what the going rate was — Treblemakers is for you.
Try it out. Search for something. If it saves you even one round of tab-juggling, we've done our job.
