Why these settings

The Hartke HD50 is an ultra-clean, flat-response solid-state bass combo with only Volume, Bass, Mid, and Treble controls (no drive channel, gain knob, or reverb). Because the amp cannot generate distortion on its own, it acts as a neutral clean pedal platform; rolling the Strat tone knob to 7 prevents the bridge pickup from sounding harsh through the aluminum-cone driver. To achieve Gilmour's signature sustain, an external fuzz like a Ram's Head Big Muff is required. First solo: switch to the neck pickup with the tone knob rolled to 6.

PRO TIPPick smoothly near the middle pickup using heavy downstrokes, and apply wide, slow vibrato strictly from the wrist once each note blooms to emulate the Hiwatt/rotary cabinet resonance.
