Pedals that stack with the Ampeg All-tube SVT

Ashdown Geezer Butler Signature

The Geezer Butler's doom-heavy bass distortion pushes the All-tube SVT's own warm growl into real heaviness.

Colorsound Overdriver

The Overdriver's transparent, treble-boosted British drive cuts through the All-tube SVT's warm growl instead of just piling on more low end.

Carl Martin Crunch Drive

The Crunch Drive's valve-driven crunch gives the SVT's warm tube growl a fuller gain stage to push into.

MXR WA38

Run the WA38's stereo, filtered chorus after the All-tube SVT's own warm growl settles, so the modulation moves a defined tone.

Demeter Compulator

Run the Compulator's subtle optical compression ahead of the SVT for even response before the amp's own warm growl reacts to it.

Alexander Pedals History Lesson Vol. 2

Run Alexander Pedals History Lesson Vol. 2 in Ampeg All-tube SVT's effects loop, clear of Ampeg All-tube SVT's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Mooer woodverb

Put the woodverb's warm, natural reverb decay in the SVT's effects loop, layered behind the amp's own tube growl. — goes in the amp's FX loop (or last, into a clean amp)
