It’s a whole new experience.

LEDs may be cheaper than LCDs and use of the unit does breed familiarity with it, but I’d rather pay the extra and get some info up front. The manual supplied with the review unit was a temporary manual. The updated Plus version therefore has the improved features necessary to make it a contender again: After holding down a key for a few seconds the speed at which the parameters scroll increases, minimising sore-pinky time.

The effects are applied in series and their parameters can be assigned to any MIDI continuous controller. 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: Like other units in this price bracket, the Plus has a bit analogue-to-digital converter. As there are so many parameters it helps if you know what they all do.

Thus, the level or decay time of reverb say can be modulated with a synthesizer’s mod wheel, or anything else that can generate Continuous Controller information. All are very smooth, authentic effects, with a lot of stereo depth. It will take quite a hefty signal before peaking. Any of 14 algorithms see ‘Effect Algorithms’ box can be chosen as the basis for an effects program, and each of the algorithms specifies which of the effects sections are utilised, exactly what type of effect is produced by each, and how audio signals are routed between them.

The EQ section in these six algorithms consists only of a low-pass filter, with programmable roll-off frequency. Whereas the Normalised Reflectivity parameter controls the reflectivity of all frequencies equally, dP damping allows the relative decay rates of high and low frequency components to be balanced – the simulated environment can 18 be made to sound more or less bright. 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 to be turned up very high in a mix for this to become obtrusive.

Running through the factory programs, the unit sounds very good, though there’s not actually a manuual variety of effects on offer – my initial impressions were of an inordinate number of variations on fairly straightforward 182 and delay combinations. The maximum delay time varies according to the algorithm used, as this determines how much processing power is available for each effect.

In the multi-effects processor wars, Digitech’s DSP Plus distinguishes itself with comprehensive facilities and little sound colouration.

Bearing in mind that the input sensitivity of the DSP Plus is mabual to cope with both line and instrument level signals, it seems that Digitech have very much kept the guitarist in mind when designing the DSP Plus. Nevertheless, the Digitech unit is still capable of producing all the important basic effects that people buy multieffects units for: An output level can be set for each effects section, apart from the filter EQthrough which the input is automatically passed.


Ian Waugh treats himself. Independent initial delay times up to 1.

If the perfect signal processor should do its job without adding any colouration to the sound, the DSP comes pretty close to perfection. Digital Multi-effects Processor by Ian Waugh.

I’d go so far as to say digittech I’d rather have another effect than EQ on a multi-effects unit, but EQ seems to go with the territory.

I found this rather odd as dspp other equipment can be reset by changing patch. But if you want to know whether it’s worth looking at and listening to, the answer is a definite yes. Some even simply flag the error and continue working.

Filter, Chorus, Multi-tap Delay 8. Parametric EQ, Chorus, Delay Its predecessor, the DSP without the Plusis capable of producing three effects simultaneously. The next algorithms I tried were the two containing the multi-tap delays, which provide stereo repeat echoes. Further parameters determine the characteristics of both the early and subsequent parts of the reverb, with pre Delay and Diffusion parameters available for both. The quality and smoothness of reverb produced by a particular diffusion level varies according to the size of mabual simulated environment, and larger environments tend to require higher diffusion values.
