505 amp settings — Cort CM15R

The Arctic Monkeys guitar tone for “505”, dialed in for a Cort CM15R with a Cort X100. Studio version, Favourite Worst Nightmare (2007)

The CM15R is a basic solid-state practice amp with limited headroom and a small speaker. The original Selmer Zodiac delivers chimey British cleans with tube warmth — your amp runs cleaner and thinner. Gain stays very low (2) to preserve clarity; mid pushed to 6 compensates for your humbucker's darker voicing vs the original's single-coil Bronco/Strat. Treble at 5 prevents harshness through the small speaker. The built-in reverb is crucial — crank it to 7 to approach that atmospheric, shimmery quality. Without a delay pedal, you lose the short slapback echo that defines the track's haunting space.
