How This List Is Built
We don't play these instruments — we're a catalog, not a review desk, and we'd rather say so than pretend otherwise. This page covers 10 of 64 roundback acoustic guitars from the Thomann catalogue, which is the largest single source of specification data in this category: 10 in detail, the rest listed with their specifications.
Position is computed, not curated. We parse the manufacturer's own description into actual values — nut width, scale, fret count, fingerboard radius, size, alloy — and rank on them: how many specifications a model has published, how many of them are measurable numbers, and how precisely it meets this page's criterion. A product image adds a little. Price is not a ranking signal: it tells you nothing about whether a neck fits your hand. The same inputs always produce the same order, so nothing here is shuffled to look fresh.
What this list is good for: narrowing a category down to a shortlist by spec and budget. What it isn't: a substitute for hearing an instrument. Before you buy, read hands-on reviews and, where you can, play it. Full methodology.
