Apr 27, 2018 The other effects (chorus, flanger, delay, phaser, tremolo/pan and pitch shifter) are mostly usable and decent. Again, this is a cheap 90's processor, so you can't expect it to be the holy grail of gear, but it's most definitely not the worst piece of effects processor that I ever heard and used. DOD 512, Reverb Effects Processor, True Stereo/Dual Mono Effects Processor, Vintage Rack. 1 knob has been replaced. Power adapter is not included. The adapter in the photos is for demonstration purposes only. Unit is Tested and Functions Well.
Starting with the technical information found in the manual: its frequency response is from 20Hz to 16kHz, the signal to noise ratio is 90dB, the sample rate is 44.1 kHz, DSP is 24 bit and A/D/A resolution is 16 bit. Now, in subjective and personal terms: it seems to work just fine with synths, mixing and voice, but somehow I found it to sound awful with my guitars. The reverbs (hall, room, plate, church, chamber, spring, studio, gated and reverse), which are the main attraction, are cold, but in a good way for certain kind of music. Of course, this ain't no Midiverb, but for a cheap 90's reverb processor you probably won't be getting much more looking elsewhere. I think that the 'spring' setting is very good for synths. 'Reverse' sucks, though, in my opinion. That reverb per se is OK, but it seems to have a huge issue with treble that can't be cut even by turning the Parameter 2 knob (which works as EQ, in the case of reverbs) all the way to the left. It's the first of two effects that suffer from sounding aggressive. The other effects (chorus, flanger, delay, phaser, tremolo/pan and pitch shifter) are mostly usable and decent. Again, this is a cheap 90's processor, so you can't expect it to be the holy grail of gear, but it's most definitely not the worst piece of effects processor that I ever heard and used. The chorus doesn't sound much warm, for instance, but in lower speeds and with the Parameter 2 knob (EQ) in the middle or to the left it can produce an interesting dark and atmospheric effect. The flanger also sounds good in some of the settings. The ones that aren't too good are tremolo and phase shifter, in my opinion: the tremolo is OK, but the control over its speed isn't very precise and therefore it ends up as nothing special, and the phase shifter has the same problem with higher frequencies as the reverse reverb, making it sound aggressive. Those two effects are examples of what was wrong with digital technology in the early to mid 90's, and I can't find myself recommending their use. At least the tremolo isn't good but isn't offensive either. Last but not least, it has a noise gate threshold pot on the back too, which you can adjust with a small screwdriver! Nice feature. All in all, a pretty honest processor that can be found for very cheap these days and doesn't sound as bad as some digital gear from the early to mid 90's. In fact, some of the effects are surprisingly good for the price! If you're in need of gear to make some 90's sounding music, or just plain collect and enjoy discovering some interesting equipments that may have slipped under your radar back in the day, as is my case, I do think that this is a good box to check out.
