01Boss SD-1 Super Overdrive
Used as a clean boost to tighten the low-end and add upper-mid bite into the amp
The Katana 50 Gen 3's Brown amp type nails the modded Marshall JCM800 core voicing used on Ride the Lightning. The SD-1 pushes the front of the amp with low drive and high level, precisely replicating how Metallica used a TS9 to cut flubby bass and add attack before the preamp. Since your Pacifica bridge humbucker has moderate output compared to Hetfield's high-output Dirty Fingers, keeping the amp gain around 6 retains punch without turning muddy.
