Why these settings

The Mustang LT25 has no mid or presence knobs on its faceplate, so mid and presence are omitted. On a Stratocaster, using position 4 (neck+middle) combined with a slight treble rollback smooths out bright single-coil bite while retaining the open, chimey Matchless-style jangle. Light gain on the Vox/Chime clean model provides just enough compression and breakup for the big chorus strums.

PRO TIPThe secret to the massive drone on 'Iris' is the alternate tuning: B-D-D-D-D-D (low B with the remaining strings tuned in unisons/octaves of D), allowing wide open strums across all strings.
