How It Works
Step 1

Enter the make, model, year, condition, and any notable features. Or use a serial number to auto-decode the model.
Step 2
Select your comps
Review a ranked pool of similar sold and active listings from Reverb, eBay, Guitar Center, and more. Check the ones to include — you stay in control.
Step 3
Review the statistics
Mean, median, high/low range, standard deviation, days on market, condition distribution, and 30-vs-90-day price trend — all calculated from your selected comps.
Step 4

Finalize the report to generate a professional PDF. Download it or send it directly to the buyer, insurer, or estate attorney from the tool.

Frequently Asked Questions
What is a CMA instrument appraisal?
A Comparative Market Analysis (CMA) appraisal identifies the value of a used instrument by comparing it to similar sold listings — the same methodology used in real estate appraisals. You select the comparable sales ("comps"), and the system calculates the statistical summary: mean, median, high/low range, standard deviation, and days-on-market. The result is a professional PDF report you can share with a buyer, insurance company, or estate attorney.
How is Treblemakers different from Mearto or other appraisal services?
Mearto charges $10–30 per appraisal, puts a human in the loop (1–2 day turnaround), and shows you limited comp data. Treblemakers aggregates real sold listings from Reverb, eBay, Guitar Center, and other marketplaces — you see more comps, you choose which ones to include, and you get your report in minutes. Starting at $8.99 per report with no waiting.
Are these appraisals accepted for insurance purposes?
Many insurance providers and estate attorneys accept CMA-style appraisals for scheduling musical instrument coverage and estate valuations, especially when they include documented comparable sales and a professional PDF. For formal USPAP-compliant appraisals required by some insurers, you may need a certified human appraiser — our reports include a methodology section and are structured to complement professional review.
What instruments can I appraise?
Electric guitars, acoustic guitars, bass guitars, amplifiers, effects pedals, keyboards, synthesizers, drums, pro audio gear, and more. Our sold comp database covers 200+ brand-model combinations across Fender, Gibson, Martin, Taylor, PRS, Ibanez, Marshall, Vox, Korg, and dozens more.
Can I white-label the reports with my own logo?
Yes — the Appraiser tier ($149/mo) supports white-label PDFs. Upload your firm logo once in your dealer profile and it replaces the Treblemakers branding on every report you generate. Your firm name appears as the report author. Ideal for insurance appraisers, estate attorneys, and multi-location dealers.
How do I get free report credits?
Dealers can earn free credits by confirming their own past sales. Link your Reverb or eBay shop in your dealer profile, and we'll show you a list of attributed sales from our database. Each sale you confirm earns 1 report credit — equivalent to 1 à la carte report ($8.99 value). Confirmed sales also display a "Confirmed by Seller" badge in all future appraisal reports using that comp.
