Why these settings

The Mustang LT25 lacks dedicated mid and presence knobs on its faceplate, so selecting the 'Rock 80s' JCM800 model provides the necessary British upper-mid push and compression naturally. The LTD EC-256 humbuckers closely mirror Ian Bairnson's Gibson Les Paul Custom, but rolling the guitar tone back slightly to 8 keeps the lead smooth rather than piercing. Delay and hall/plate reverb from the onboard presets are essential to emulate the Abbey Road studio ambiance.

PRO TIPIan Bairnson's signature sound on this track comes from a slow, wide, singing vibrato using the meat of the fretting finger rather than rapid wrist shaking—dig into the whole-step bends and let the delay trail catch each release.
