I suspect the casing was manufactured before the list of parameters had been finalised – but then 1228 if you wanted to place the unit directly below another in a rack?

Previous Article in this issue Finale. SOUNDING OFF Running through the factory programs, the unit sounds very good, though there’s not actually a huge variety of effects on offer – my initial impressions were of an inordinate number of variations on fairly straightforward reverb and delay combinations. Hopefully, by the time you read this, a current manual will be available.

In the multi-effects processor wars, Digitech’s DSP Plus distinguishes itself with comprehensive facilities and little sound colouration. A slight limitation to the usefulness of this realtime control over effects parameters is that changes in parameter values do produce slight ‘zipper noise’ a series of clicks generated as the values incrementbut the pure effect level has digjtech be turned up very high in a mix for this to become obtrusive.

Next door to the display are four cursor keys which are used to access the programs and change the parameters.

Good though this is, the fact that it comes after the release of the ART Multiverb and Alesis Quadraverb somewhat takes the edge off the excitement. Extremely useful for live work. An output level can be set for each effects section, apart from the filter EQthrough which the input is automatically passed.

In practice, to kill the effect I found it far easier to turn the Mix control manul Dry.

Other, perhaps, than the lack of a MIDI program reference table, the pros and cons balance each other reasonably well. Not particularly friendly, to my way of thinking. Nevertheless, the Digitech unit is still capable of producing all the important basic effects that people buy multieffects units for: What is lacking, however, is a table to let you assign a program number to any incoming patch change message.


If you’re in the market for a high quality, powerful and versatile effects processor, details like these will determine which of the competing units is right for you, and should you opt for the DSP Plus, you’d be hard pushed to find fault with it.

Also, the pages which should have contained details of the factory presets were totally blank so the uses to which some of the presets could be put were not always obvious.

I began this review by outlining the way in which our perceptions of new products are radically affected by what has come before. This is a sad omission as it means you have to configure your other equipment to the DSP and not the other way around, digitefh it should surely be.

With distinctive effects like this, it’s very easy to grow tired of them quickly if they sound identical every time you use them. Further left along the panel is a four by three grid which shows the range of effects allowed by the current algorithm coming up. I’d go so far as to say that I’d rather have another effect than EQ on a multi-effects unit, but EQ seems to go with the territory.

It seems that at each stage of the effects chain, where a level for any section is set, what is actually being specified is a mix balance between the signal at the input and output of that section: I found that setting this parameter to more than 7 from produced a very harsh, artificial sweep, more like a filter envelope closing down sharply than a natural damping.

A good trick is to set the initial delay times for the three stereo positions to almost – but not quite – the same value.

Searchable archive of old, out-of-print music rsp magazines. The Ultimate Reverb algorithm allows huge scope for creating your own reverb effects, but it does take a little time and experimentation to get the best out of it.

Some of the more interesting factory programs feature heavily flanged echoes, a combination of delay and reverse or gated reverb effects ranging from the subtle to the bizarre, and a good number of pure reverb programs.

The default configurations for these are bypass and to switch in infinite repeat, but they can be reconfigured to step manhal and forwards through the programs and they can be used with DigiTech’s three-button footswitches FS and FS to step through diggitech program numbers. In the absence of program names, this is really useful. You can’t save or load just one program, however, so if you wanted to combine programs from two separate banks you’ll have to note the values of the parameters of one set and enter them manually, but that shouldn’t take long.

According to the manual, the reverb decay time in seconds is the product of the numerical values of these two dititech I do feel that a few areas of the Plus’ implementation could be tidied up, however – although what you lose on mamual swings you gain on the roundabouts I hate that expression.

Its predecessor, the DSP without the Plusis capable of producing three effects simultaneously. You can obviously colour a sound with chorusing, flanging and so on, but the quality of the output vis-a-vis the input is pretty pure.

It admits as much in the introduction and says that the DSP software was still being developed while the manual was being written. The Program Copy function transfers the contents of a program to a new location and that will help. Review by Ian Waugh. The effects produced by the DSP Plus emanate from four processing sections: Its digitedh weaknesses are that it does not offer quite the flexibility or programming ease of either of its main rivals.
