01Dunlop Cry Baby Wah (or similar)

RECOMMENDED — not currently owned. Leave in fixed 'cocked' position at ~60-70% travel (toe partially down), do NOT rock it. This is essential for the intro's nasal mid-range character.

Why these settings

Your JCM900 is gain-ier and brighter than Slash's Super Lead/Jubilee, so gain drops from his ~6-7 to 5 to avoid fizz. Your Telecaster's single coils are brighter and lower output than his Les Paul humbuckers — treble drops to 6, mids push to 6 to compensate for the Tele's natural scoop, and tone knob rolls harder (to 5) to replicate the dark vocal quality his Les Paul neck pickup achieved at 6-7.

PRO TIPThe cocked wah is non-negotiable for the intro's sound — without it, you'll get a clean neck-pickup tone but miss the nasal 'honk' entirely. If you can't get a wah, set your amp's mid to 7 and presence to 6 as a partial workaround, but the real fix is a $50 used Cry Baby parked at 60% travel.
