Roger Mayer Vision Series Octavia 
The Vision Octavia retains the classic tone and circuitry of the Rocket Octavia, but has an added tone knob as well as the added conveniences of a power supply jack and a smaller more pedal board friendly size.  The OCTAVIA is probably our most famous and distinctive creation.  This effect was designed in early 1967 and featured on "Purple Haze" and "Fire" by Jimi Hendrix.  It's unique tones can also be heard on such tracks as "One Rainy ", "Little Miss Lover", "Little Wing", "Machine Gun" etc.  The OCTAVIA produces a sound that is an octave higher than the note you are presently playing.  This doubling effect is accomplished through electronic mirror imaging techniques that are program sensitive and also respond to the feed forward inputs of the player.  The electronic circuitry is analogue in design and will react faithfully to all the subtleties and harmonic overtones from the guitar.  The effect produced is very unique but human in quality.  The units that are manufactured today are representative of the latest evolution of Octavia that Jimi used and contains the feed forward and gating effect that my earlier evolutions lacked.  Electronically the OCTAVIA is an analogue circuit with the properties of a frequency doubler, envelope generator and amplitude modulator with addition frequency shaping filter circuits.  The effect produced is subtle to wild depending on the settings used and will respond to the attack of the player.  A clean tone from the guitar with the tone rolled control rolled off will produce "ring modulated" overtones that characterise the solo to "Who knows ".  The sound is tangibly different if a fuzz unit is in front of the Octavia: an upper octave double is created, clearly demonstrated in the solo to "Purple Haze".  The bright harmonics are more controllable if the neck pickup is selected and the tone control set to roll off the treble.  The effect really comes into it's own on the top E and B strings from the 7th fret up.  A clean and precise picking style is essential with particular attention to accurate fretting techniques.  Jimi placed the Octavia after a fuzz and wah unit in most cases so it would react to the combined effects of both the wah and one or more fuzz boxes.  It is important to experiment with how much signal you are driving the Octavia with as this has a great influence on the sound produced.  The Octavia now also comes in the brand new Vision Series enclosure design with the same famous sound and many added extras to help the modern musician and bring the famous Octavia sound forward to the future.  The many players who demand the original sound plus a package that is more flexible and pedal board friendly will welcome the additional features and for the purists the famous Rocket Styled Octavia will still be available.

Roger Mayer Vision Series Voodoo-Vibe Jr  History: The Voodoo-Vibe Jr is our latest evolution of the Univibe unit that was used by Jimi Hendrix and Robin Trower.  The Voodoo-Vibe Jr will faithfully reproduce all the old sounds and incorporates the modifications I made for Jimi.  The Supervibe was my 1st evolution of the Univibe and many leading performers including Stevie Ray Vaughan and Robin Trower used this unit.  The Voodoo-Vibe is the 2nd evolution and also has a Tremolo circuit plus the usual Chorus and Vibrato functions.  The control of the sound parameters is greatly expanded and is capable of producing many new unheard effects.  The Voodoo-Vibe Jr is the 3rd evolution and is the smaller brother of our famous Voodoo-Vibe, which is used by so many great guitarists such as Page and Clapton and still today remains the standard by which all other Vibe type clones are judged.  It has been designed in response to the many requests of having a smaller unit with less knobs that still gives the great tone of it's bigger and more complicated brother.  The Vibe Jr. has the same circuitry and configuration but does not have the Tremolo function nor does it have the choice of sine or triangular waveforms in three ranges and the symmetry controls.
Technical: The Voodoo-Vibe Jr is completely analogue in operation and exhibits a very transparent and full sound quality that is lacking in digital units that simulate chorus, flanging, phasing and vibrato effects.  The digital zipper noise and graininess is eliminated and the guitar tone is maintained throughout the full dynamic range, Class A discrete circuitry is used in all audio stages and results in ultra high audio quality and very low noise.  The signal to noise ratio of the unit is 102Db, which is about 12 Db better than a compact disc.  Extensive power supply filtering is used to ensure low noise operation from mains AC adapters. Front Panel Controls:  SPEED:  The speed or rate of effect can be adjusted over a large range. INTENSITY:  The level of depth of the effect can be controlled and is used in conjunction with the other controls to set up the final effect. SWEEP:  This control enables the unit to be tuned to produce different sweep effects from the Chorus and Vibrato mix.  It changes the frequency around which the unit sweeps (centre frequency).  If the mix control is set to full chorus the sweep can first be set to a good starting point by turning the Intensity control to minimum and then rotating the sweep control slowly whilst playing a chord until a phasing or null is heard.  This should occur at about the 2 o'clock position of the sweep dial. Increase then the intensity control now and a very typical Univibe effect will be heard. When the Mix control is set at the full Vibrato setting the effects of the sweep control will not be as great as this is a pitch shift effect. MIX:  This sets the mix or blend of chorus and vibrato effect. QUICK START:  Turning all the controls to the 12oclock position will give a good starting point to begin experiencing the interplay of the controls.  The operational window of these controls has been optimised to produce great tones instantly.  The simplicity of operation will appeal to those who are less technically orientated and who want a plug in and go version of the Voodoo-Vibe that was a bit too complicated for them. |

Roger Mayer Vision Series Concord +  The Concorde+ Treble Booster is housed in the new Vision Series enclosure design and uses both silicon and germanium transistors in a unique configuration to obtain the best tone qualities from the marriage.  When I first started designing pedals in 1961 I produced a Treble Booster that was tried and used by my friends including Jimmy Page who then played in local bands.  The circuit configuration I used was a standard textbook example but required careful attention to biasing and selection of transistors to obtain the best from this simple circuit.  There were many subsequent commercial versions produced in the 1960's of this type of circuit that followed after the time I first designed mine and now I have designed and produced a much more flexible and enhanced version of my early design.  The modern clones produced today of the ultra simple 1960 type treble boosters lack in flexibility and in my opinion are of very limited use.  The Concorde + however departs from the clones and uses a unique approach of combining a low noise class A silicon drive circuit with passive tone shaping to drive a fully optimised germanium treble booster.  This results in giving the simple circuit new life and explores its sonic boundaries to the maximum.  It is now possible to add drive and distortion with EQ before the treble booster section.  It is also possible to set the silicon drive section to drive the treble booster section much harder than any guitar pickup could ever do without any added distortion but with the added feature or having EQ prior to the treble booster.  So if you want the qualities of soft germanium type distortion overload characteristics that this circuit will produce or you want to explore the more radical germanium distortion possibilities the Concorde+ will oblige.  The front panels controls of Drive, Tone and Output control the many tone variations and brings the humble treble booster forward to the future.
The Concorde+ comes in a brand new enclosure design with many added extras to help the modern musician.  Many players demand a package that is more modern, flexible and pedal board friendly and will welcome the additional features.

Roger Mayer Vision Series Crossroads Signal Director  The Crossroads Signal Director has been developed in response to the need for a device
that switches a signal from an instrument to two different devices.  The switching action
is activated by a footswitch mounted on the top of the unit and has two switching modes
that can be selected on the side of the unit by a slide switch.  Mode 1: This mode allows the signal to be directed to Output A or Output B and can also be represented as A or B. Mode 2: This mode allows the signal to be directed to Output A and Output B and can also be represented as A + B.  The footswitch in this mode turns Output A on or off, while Output B is always active. The two switching modes are made much more flexible and have many more advantages by the fact that Output A is transformer balanced.  The type of transformer that we use is manufactured from the latest high performance wideband ferrite material and is audibly transparent with a frequency response that extends to over 100KHz.  It is very important to have one of the outputs balanced because in many cases when connecting several devices together in parallel a ground loop is formed causing hum and interference.  Safety from electrical shocks is eliminated when connecting two amplifiers in parallel because both electrical earth connections can be left connected and not lifted to eliminate the ground loop hum as is the usual and very dangerous solution used by many players.  The reason you should not in any instance lift the ground to get rid of hum is because if there is an electrical fault in the amplifier that has its ground lifted, there is a great risk of you receiving a potentially lethal electric shock.  The other advantage especially for guitar players when performing in locations where you are getting electrical shocks between the guitar and say the microphone stand is the ability to use the balanced output to effectively and safely isolate the guitar from everything.  Only the balanced output should be connected in this case to provide a fully floating situation thus providing full safety. Simple previous designs of A/B boxes that are purely passive in design do not provide any of the above safety features and suffer many problems of clicks and noise when used in many situations.  The Crossroads Signal Director has been especially designed to provide electrical operating safety with professional studio quality electronics and design techniques producing a modern design evolution. The Crossroads Signal Director is active in design using a conventional 9V battery with an operational life of over 85Hrs.  It can be also used with an external DC power supply of 9- 15V, it is recommended to use a regulated power supply but extensive internal filtering will provide noise free operation with virtually all power supplies.  It has a very high input impedance of over 500K and both A + B outputs have very low output impedance designed to drive long cables without any loss of high frequency or interface with other equipment designed to work at -20Dbu levels.  LED Indicators show which outputs have been selected.  Absolute no noise and click free switching with no bleed through of signal to the other channel are provided which is an absolute must when used in the A or B mode. Applications: Driving 2 amplifiers in A + B or A or B modes for different amp tones.  In recording applications as a direct box with balanced output to desk.  On stage to provide fully floating guitar with full electrical safety. Use as a tuner buffer and mute.  To direct signal to two different parallel signal processing paths. | |
