Why this number?
The typical used price is the median of 13 used sales observed in the last 24 months, with outliers removed and the figure rounded. An observed sale is often the last asking price rather than a confirmed hammer price.
| Typical used price | €35 | median sold, rounded |
| Most sold between | €35–€40 | 25th to 75th percentile, same window |
| Window | last 24 months | the tightest of 90 days, 6 months and 24 months with 8 used sales |
| Sample | 13 used sales | thin data, treat as a rough guide |
| By condition | same as typical | excellent, median of 9 sales, same window |
| Time to sell | — | only counted from listings we watch start to finish; not enough yet |
| Outliers | dropped | beyond 10× the product’s own median: bundles, parts, typos |
| All-time | €45 | 38 used sales, 2020–2026; not used for deals |
| Sales on record | 51 | all-time, all platforms |
| Closest new | €27 | Behringer 921A Oscillator Driver Eurorack Synthesizer Module at Thomann; a relative’s price, not this model’s |

The best-priced as cards, a row of them; every other ad as a line, by ask. Each ask is the seller’s own number; the platform’s mark opens the listing. Each one says when we last confirmed it at its source: the price and availability are from that visit, so check the marketplace before you go.
ReverbPrice history
Every recorded sale, one point each: 51 of them, placed by the day the ad went up. Too few sales to draw a trend through them without inventing one, so the points speak for themselves. Condition is mixed, so some of the spread is a mint against a fair rather than the market moving.
