Dubstation has been a fixture in dub, electronic, and pop production for nearly twenty years. It emulates the analog bucket-brigade delays of the 1970s and 80s, with their pitch-bending, warmth, and gradual high-frequency loss intact, then adds things those circuits could never do: true stereo dual-time delays, ping-pong, a stereo LFO, and a clean digital looper with overdub and reverse. Sound and Character The bucket-brigade model is the real thing: the high-cut frequency tightens as delay time gets longer, exactly like the original hardware. A low-cut filter trims the bass for the thin echoes of early Jamaican dub. A saturation stage on the feedback path adds analog-style breakup as repeats stack up, and the LFO modulates delay time for chorus, flange, and pitch swoops. Looper and Reverse The LOOP switch turns Dubstation into a clean digital looper that holds the buffer indefinitely and accepts overdubs. This is different from cranking the feedback, which degrades and distorts the signal over time. The REVERSE switch flips the delay memory backwards, and combined with the looper produces reverse loops that hold their fidelity indefinitely.
