RECOMMENDED — not currently owned. Essential for the tight, focused bay area thrash tone. Without this, the DSL's gain will be flabbier in the low end. A Boss SD-1 or TC Electronic Cinders works as a budget substitute.

Why these settings

Your Strat's single coils are lower output and brighter than the original Ibanez humbuckers. Gain is pushed to 7 (vs ~5-6 on a humbucker rig) to compensate for the weaker signal, and treble stays high because the DSL's Ultra Gain channel is darker than a vintage JCM800. Mid is scooped to 4 to get the thrash 'V-curve' but not as low as a Rectifier sound — the JCM800 original had more midrange bite than modern metal tones.

PRO TIPPalm mute right at the bridge saddles with the heel of your hand for maximum tightness. The Strat's bright attack actually helps thrash articulation — lean into fast alternate picking and let the single coil's clarity cut through. If the tone is too thin, try the bridge+middle position for a fatter sound while keeping attack.
