What’s your objection to letting through the full dry signal, guys? Further parameters determine the characteristics of both the early and subsequent parts of the reverb, with pre Delay and Diffusion parameters available for both. Perhaps software upgrades are in Digitech’s corporate mind – a software upgrade has got to be a better prospect than realising your unit has depreciated to less than half its cost and shelling out all over again.

One aspect of these algorithms that is common to other MSEPs is that there is a trade-off between the number and complexity of effects used. Having created an environment of the right size, the next aspect of the reverb effect you might choose to change is the position of the listener relative to the sound source, using the Early Reflection Level and Subsequent Reflection Level parameters.

This caused me a moment of confusion initially, as I was expecting to find some means of controlling the routing of the effects signal, however it actually makes the unit much easier to use, albeit at the expense of a little flexibility. Like other units in this price bracket, the Plus has a bit analogue-to-digital converter.

The display will also show changes made to a a parameter’s values from a MIDI controller – a useful function. Please include your email address if you want to be contacted regarding your note. This is not a particularly powerful tonal tool, though it is at mnaual quiet.


The quality and smoothness of reverb produced by a particular diffusion level varies according to the size of the simulated digitdch, and larger environments tend to require higher diffusion values. It’s a whole new experience. An Effect button kills the processed signal but the volume of dry signal it allows through is dependent upon the setting of the Output Mix knob the QuadraVerb Bypass button works in a similar way.

Take Your Bass to the Next Level. Its quoted frequency response is 20Hz to 20kHz with a signal-to-noise ratio of around 85dB. Previous Article in this issue Source Of Inspiration. In true LED style, “v”s look like “u”s, and “t” looks like a capital “E” with the top line missing.


If you use a high feedback rate you can build up little pieces of music, a la Terry Riley, for example. The Plus is capable ssp producing four.

The first six algorithms the only ones to allow four effects at once have a maximum delay time of 0. 218 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.

Hot on the heels of the Multiverb and Quadraverb comes Digitech’s contender for the title of best ‘four effects at once’ signal processor. 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. The LED display can be varied so that as you change parameters they scroll into digiyech display area or pop into it.


If you’re enjoying the site, please consider supporting me to help build this archive When you switch on you go back to program one, not the last program used, so you’d have to reselect the desired program again. Whereas the Normalised Reflectivity parameter controls the reflectivity of all frequencies equally, dP manua, allows the relative decay rates of high and low frequency components to be balanced – the simulated environment can therefore be made to sound more or less bright.

In practice, to kill the effect I found it far easier to turn the Mix control to Dry. Large room, Delay, Chorus, Filter 2.

I tried this out with the maximum values for both, and though it was quite hard to decide on a point where the reverb tail was actually quieter than the noise floor when it decays this slowly, there was undoubtedly around a minute and a half of beautifully decaying reverb. It has three rotary dials on the front to set input and output levels and the mix between the dry signal and the processed signal.

Medium room, Delay, Flange Filter 5. This is a sad omission as it means you have to digiech your other equipment to the DSP and not the other way around, as it should surely be.
