Klon KTR

Carl Martin PlexiTone

Run Carl Martin PlexiTone into that transparent platform and it finally gets some high gain

Sola Sound Tone Bender MkII

Walrus Audio Mako R1 Reverb MkII

Run Walrus Audio Mako R1 Reverb MkII in Engl E600 Ironball Combo's effects loop, clear of Engl E600 Ironball Combo's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
