Place FIRST in chain before any drive — this mimics O'Connell's unconventional reverb-before-dirt signal flow that creates the washy, snare-in-a-huge-room texture
Original uses Fender cleans with bright switch for piercing shimmer. Your DSL20HR is mid-forward and darker than a Twin Reverb — raise treble +1 and presence +1 vs a typical Fender setting to recover that sparkle. Classic Gain channel at low gain captures the slight edge-of-breakup character. The key trick is reverb FIRST in chain — O'Connell deliberately runs dirty reverb for that atmospheric wash.
