Pedals that stack with the SolidGoldFX If 6 Was 9 MKII

Walrus Audio Julia

Walrus Audio Julia's modulated voice goes after SolidGoldFX If 6 Was 9 MKII in the signal chain — it's not there to compete with SolidGoldFX If 6 Was 9 MKII's own fuzzy character

MXR Micro Amp

MXR Micro Amp stacks clean boost on top of the fuzzy already here

Walrus Audio Ages

Run fuzzy into Walrus Audio Ages for more clean boost on top

Electro-Harmonix Deluxe Memory Man

Keep Electro-Harmonix Deluxe Memory Man after SolidGoldFX If 6 Was 9 MKII in the signal chain, clear of SolidGoldFX If 6 Was 9 MKII's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Electro-Harmonix Memory Boy Analog Delay

Put Electro-Harmonix Memory Boy Analog Delay after SolidGoldFX If 6 Was 9 MKII in the signal chain, clear of SolidGoldFX If 6 Was 9 MKII's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

PRS Mary-Cries Compressor

PRS Mary-Cries Compressor's own clean boost character is the real reason this is worth trying
