Off the top of my head I remember these (I hope I'm gettined 'em more of less right!) The first was black with blue/grey trim and had large grey buttons and rates of 900, 1900, 3600 I believe. These are still around cheap but for some reason are often missing the buttons. I'd be curious if anyone has found a source for replacements. Then there were the black with dark blue and slimline black buttons which were slightly better noise spec. Later versions of these added a switch for triggering the "loop" you saved. Times were changed to 3900 MS on some of these and they added the 7900 (8?) sec unit somewhere in here as well. I have one of these without the trigger button but it does have a button for hold that doesn't appear on any other unit. I believe I have the 3600 so they mixed and matched tiome quite a bit during this phase. The final series was the white faced units which had the trigger and were in 2,4 and 8 sec increments. I think this then led into the DPwhatever series and they stopped making specific delays. this unit looks like other digitech stuff of the time (Metal Machine, HM Harmonizer, etc). All the RDS units have a speed, width, and depth knob plus in and out, feedback, level and a mix type knob. Some have invert buttons (I think this was added in the second series) and a 1/4" invert out as well. also before the PDS2000 "echomachine" there was the PDS1002 a 2 second digital delay with infinite repeat. This has got to me the most versitle and affordable delay pedal ever made. Used these show up for $75 a lot which is a great price/performance ration IMO. as said above the PDS pedals only have a switch for range (0-50, 50-500, 500-2000 MS) and knobs for delay time, regneration, in and out, and mix (again going from memory). Quite honestly the in and outs don't do too much on these. years ago I threw one at my guitar player and sheared these two knobs off. I've never noticed a difference (I don't reccomed thorwing them BTW I'm not a role model...) If anyone's *really* interested I could try and dig up all my old digitech catalogs. I remember studying the RDS series when i had no money and they kept changing them every year so i never could decide what to get... ----------------------------------------------------------------------- HELP WANTED PRODUCTIONS - Http://www.voicenet.com/~legion "Bringing you the best in Organic Electronic music since we started..."
