Pedals that stack with the Acus One Forstrings 4 Ferdi

Ashdown Geezer Butler Signature

The Geezer Butler's doom-heavy bass distortion is a much heavier gain than the Ferdi's own natural, acoustic-voiced clean offers on its own.

Boss ODB-3

The ODB-3's fundamental, EQ'd bass overdrive gives the Ferdi's natural acoustic-electric clean real gain to push into.

Fulltone OCD Obsessive Compulsive Drive

The OCD's overtone-rich clipping pushes the Ferdi's natural, acoustic-voiced clean into real, unexpected drive.

MXR M117R Flanger

Add the M117R's warm, vintage flange on top of the Ferdi's own natural, acoustic-electric clean for subtle texture.

Xotic SP Compressor

Run the SP Compressor before the Ferdi for subtle, harmonic sparkle before the amp's own natural acoustic voice reacts.

Binson Echorec Delay

Run the Echorec in the Ferdi's loop for saturated, rhythmic echo beyond the amp's own natural acoustic-electric voice. — goes in the amp's FX loop (or last, into a clean amp)

Mad Professor Deep Blue Delay

Keep the Deep Blue in the Ferdi's loop for simple, dry tape-echo character beyond the amp's own natural acoustic voice. — goes in the amp's FX loop (or last, into a clean amp)
