Price history
Every recorded sale, one point each: 123 of them, placed by the day the ad went up. The line follows the middle of the sales around each point, with the middle half behind it, and breaks wherever nothing sold nearby. Condition is mixed, so some of the spread is a mint against a fair rather than the market moving.

In one paragraph
The page's figures as one paragraph, assembled for quoting; not written by hand.
Sellers are asking a median of €400 for the Boss Katana-100 Gen 3 today, 38% over the €290 it actually sells for (8 recorded sales, last 90 days; most sold between €290 and €300). New, it costs €425 at Thomann (read 28 August 2026), so a used one at the median saves about 32%. There are 99 listings live right now across Reverb, eBay United States, from €295 asking. Figures computed 18 October 2026 by Doirado from cross-platform listing data.
