Pedals that stack with the Gibson GA-18

EarthQuaker Devices Arrows

Where this leans warm, EarthQuaker Devices Arrows answers back bright

Catalinbread RAH

Where this leans warm, Catalinbread RAH answers back bright

Catalinbread Galileo

Catalinbread Galileo leans bright right where the warm tone needs it

Tone City Summer Orange

Tone City Summer Orange's modulated voice goes after Gibson GA-18 in the signal chain — it's not there to compete with Gibson GA-18's own edge of breakup character

JHS 3 Series Compressor

JHS 3 Series Compressor's own compressed character is the real reason this is worth trying

Catalinbread Csidman Ghost

Keep Gibson GA-18's edge of breakup voice out front: Catalinbread Csidman Ghost goes in Gibson GA-18's effects loop so its pristine voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)

NuX Atlantic

Put NuX Atlantic in Gibson GA-18's effects loop, clear of Gibson GA-18's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
