(someone had asked about the difference between the delay functions of the RSD-10 and the RDD-10. i'll post my response here if anyone is interested...)
... here's a bit of a rundown on how the normal delay functionality compares on both units:
RSD-10
- 2ms to 2 seconds delay time, via five delay modes (8ms, 32ms, 125ms, 500ms, 2000ms)
- fine tune control for delay time (0.25x - 1x for each mode)
- feedback control
- delay volume level control
- 1/4" and RCA mono in/out
RDD-10
- 0.4ms to 400ms delay time, via nine delay modes (1.5ms, 3ms, 6ms, 12.5ms, 25ms, 50ms, 100ms, 200ms, 400ms)
- fine tune control for delay time (0.5x - 1x for each mode)
- delay time modulation (rate and depth controls)
- feedback control
- tone control (filters out highs from delay repeats, can make it sound more like an analog delay)
- delay volume level control
- 1/4" and RCA mono input
- 1/4" and RCA mono outputs (one for dry/wet mix, and one for delay only)
- 1/4" modulation input (for foot pedal, etc)
the RSD-10 has a separate sampling function (four modes), which can sample up to two seconds and be triggered in a number of different ways. the manual for the RSD-10 can be found here:
