KX507 Multi-Scale

Heavy Core on 7-string players needing tight low tuning — hybrid 10-48 foundation matches multi-scale construction.

M-Steel on Cort KX507 — Maraging steel matches active Fishman Fluence pickups for maximum output.

NYXL on KX507 — 7-string players use 6-string sets plus individual low-B; NYXL for tuning stability.

Unconventional: progressive-tension balanced sets on a budget extended-range. The Cort KX507 Multi-Scale is one of the cheapest seven-string multi-scale guitars on the market — the default string choice is standard seven-string sets from D'Addario or Ernie Ball (10-59 or thereabouts). Kalium Strings is a boutique American maker whose progressive-tension 7-string sets cost 3x the D'Addario price, and the entire idea of buying $40 strings for a $600 guitar offends most beginner-djent buyers.

But the Asian djent underground — Indonesian and Malaysian bedroom producers recording on YouTube's 'djent tutorial' ecosystem, Polyphia-influenced players who study Tim Henson's studio setups, and extended-range guitarists on the sevenstring.org and djentclub forums — run Kalium specifically on budget multi-scales because the progressive-tension balance compensates for inconsistencies in affordable multi-scale fret-spacing. What you get: perfectly even string feel across the fanned fret layout, low-B that feels proportional to the high strings, and the tonal consistency that the KX507's affordable construction otherwise lacks. What you sacrifice: ~$30 more per restring, a 6-week wait for custom gauges, and the ability to buy replacement singles locally.

Best for serious budget-djent players doing studio tracking; skip it for bedroom practice or live gigs where string breaks mid-set can't wait for shipping.
