Amps that pair well with the Boss DD-2 Digital Delay

Phil Jones BP-800 Bass Pulse 800W Head

Keep Phil Jones BP-800 Bass Pulse 800W Head's transparent voice out front: Boss DD-2 Digital Delay goes in Phil Jones BP-800 Bass Pulse 800W Head's effects loop so its transparent voice doesn't muddy it

Phil Jones X4C NanoBass 35W 1x4 Combo

Run Boss DD-2 Digital Delay in Phil Jones X4C NanoBass 35W 1x4 Combo's effects loop, clear of Phil Jones X4C NanoBass 35W 1x4 Combo's own gain stage

Ampeg BA 108

Put the DD-2's clean, musical delay in the BA 108's effects loop, after the amp's own mid-forward practice voicing does its work.
