Why these settings

The Blues Junior's EL84 power section is naturally warmer and breaks up earlier than Gilmour's ultra-clean Hiwatt DR103 headroom, so Volume (gain) is capped at 4 to keep the tone transparent yet singing. The amp's Fat switch is kept OFF to prevent low-mid muddiness, while Mids are set to 6 to emulate the focused midrange push of the Colorsound Power Boost. Adding an external analog/tape delay and compressor pedal will fully capture the spacious, sustained studio atmosphere.

PRO TIPPick firmly with the flesh and edge of a heavy tear-drop pick near the neck pickup, letting the initial transient ring cleanly before applying Gilmour's signature wide, slow vibrato.
