Line 6 Verbzilla

The Verbzilla from Line 6 features 11 reverb models in a single stomp box.

The verbzilla, powered by either a 9 Volt Battery or DC Power supply, features Mix, Decay, Time, Tone controls to allow the user to customize the available tones.

Line 6 Verbzilla list of controls

Mix – Allows you to control the amount of reverb in your signal from dry to 100% wet.

Decay – Controls how quickly the reverb tail fades to silence.

Time – Controls the length of pre-delay. This is the amount of delay before the signal hits the reverb chamber.

Tone – Allows you to adjust the tonal character of the reverb, giving you the flexibility to go from dark and subtle to bright and splashy.

Trails Switch – When switched on, Verbzilla’s processing is engaged while in bypass, so reverb smoothly trails away when you kick the effect off.

The unit also features a model switch to allow the user to select the type of reverb to be used these include spring reverb, Hall, Chamber. The unit also comes with a tone called Octo that provides harmonized decay similar to the “shimmer” effect employed by U2’s The Edge.

So if you wanna get that U2 harmonic shimmer sound the Verbzilla is a must (check out this youtube vid if you need convincing!

U2′s The Edge Shimmer Effects

U2′s Guitarist “The Edge” is often well known for using a seemingly vast array of guitar effects. In particular his sound is often enhanced through the use of delay or echo. Another common sound that he uses is known as the Shimmer effect.

The Shimmer effect is reminiscent of an orchestra or strings and can be heard in songs such as “With or Without You”, “4th of July”. U2 often use the effect live and it can be heard during the opening introduction to the song “City of Blinding Lights”.

The sound originally developed during the recording of The Unforgettable Fire album and was created by The Edge and the albums producer (Brian Eno).

The effect was created by splitting the signal at the beginning so that you still hear the normal guitar sound, the other part of the signal is then heavily treated (in the studio via an AMS 1580S) with a harmonizer/delay then a heavy reverb.

The Harmonizer/Delay works by treating each note by harmonizing the delay an octave higher than the original note, the next delay is two octaves higher, next is three, etc. It then gets a heavy dose of plate reverb. This sound appears to constantly shift which creates the “swell”-like effect.

There are only a handful of units that can produce this sound. The AMS unit is one, U2 are also known to use the Eventide Eclipse. The new Line 6 Verbzilla also produces a similar effect by using the “Octo” reverb.

What does tell us? Well, with a bit of imagination, experimentation and some technical know-how you can create some really interesting sonic landscapes with the guitar which can alter the dynamic of your music and make your band sound bigger than it actually is!.

Korg A3


The Korg A3, now out of production, was originally released during the 1980’ and is fondly remembered as one of the best of the early rack mount effects units. Korg marketed the A3 an all in one multi Digital multi effects unit. The unit had 19 built in effects groups including 41 different types of effects to choose from and came with 20 built in effects chains. The chains and individual parameter settings of each effect could be edited and stored in one of 100 program slots on the RAM memory.

Effects available included reverb, compressor, distortion, delay, stereo delay, modulation delay, phaser, pitch shift and EQ. The A3 included Korg’s Digital Signal Processor which aimed to eliminate signal degradation. The A3 also utilized 4 times over sampling techniques to preserve the tones and provide a high quality output. The A3 allowed upto 6 effects at once which could be set up in a chain – the chain could then have his it’s own master volume, noise gate etc.

Users were able to upgrade the A3 through adding expansion cards which upped the number of presets and effects available. There was also an optional foot controller (the FC6) which enabled the user to control the unit via stomp boxes, especially useful during live situations.

The A3 did have some problems associated with it’s design – the soldering on the circuit mounted input/output jacks could be temperamental and loosen or break from time to time – necessitating minor repair work – backlights for the screen could also fail over time. Given the A3’s age the expansion cards can also be hard to come by (check out the usual auction sites) – these really are a must if you want to get the full A3 experience.

The A3 was widely used within the music industry (not just as a guitar unit!) and presets can often be heard if you listen close enough – one of the A3’s famous users was U2’s The Edge – take a listen to Mysterious Ways from the Achtung Baby cd and you can hear the Korg A3 in all it’s glory.

Where the A3 sits against today’s units is debatable – the POD XT series for example has such a range of effects and modeling capabilities that the A3 isn’t really able to compete – however what the A3 can offer is a range of impressive tones that would grace any guitarists sound.

As we said the A3 is now out of production – units crop up on auction sites from time to time for fairly reasonable prices – a quick search on google should be able to source the files needed to replicate the expansion cards – throw in a foot switch and you’ll have a great vintage unit capable of a broad range of tonal options.
