Pedals that stack with the Roland DB-500 D-Bass Combo

EarthQuaker Devices Hizumitas

EarthQuaker Devices Hizumitas's high gain fills in what this high headroom tone doesn't make on its own

MXR ZW90 Wylde Phase

Put MXR ZW90 Wylde Phase after Roland DB-500 D-Bass Combo in the signal chain, clear of Roland DB-500 D-Bass Combo's own gain stage

Lab Ratz 3D Boum Warming Unit

Binson Echorec Delay

Keep Roland DB-500 D-Bass Combo's high headroom voice out front: Binson Echorec Delay goes in Roland DB-500 D-Bass Combo's effects loop so its saturated voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)

Mad Professor Deep Blue Delay

Mad Professor Deep Blue Delay's analog warmth voice goes in Roland DB-500 D-Bass Combo's effects loop — it's not there to compete with Roland DB-500 D-Bass Combo's own high headroom character — goes in the amp's FX loop (or last, into a clean amp)
