Ok, so you have eight effects pedals which you use regularly. You use various combinations of these pedals in various songs, but you are not good at tap dancing…or you are just clumsy and have (once or twice) stepped on the ultra tricked out-metalized-distortion pedal for the lead in your one ABBA cover. You have seen the digital effects controllers they use on the big stages, and have secretly yearned for one… even though you may never make the big stage. Enter Thomas Guldmann’s Octa-switch MK3. Your eight effects plug into the eight effects-loops on the back of this unit (all true-bypass, impedance free, gold relays so you can run any of your pedals, new and old without problem), and then by turning on or off the numbered switches in each of eight DIP Bank switches, you determine which effects you wish to use simultaneously in each Bank. There is a blue LED for every effects loop used and for each Bank (so once you are programmed, when you step on Bank 6 you will see the lights of all the effects you have assigned to Bank 6 and the Bank 6 LED). The Octa-switch MK3 has incorporated a couple new features as well! The ninth switch on the left side of the case is a BYPASS Switch….this allows you to completely bypass all eight pedals and enjoy only the unaffected sound of your amplifier. There are also two External Switching jacks which allow you to use two amplifiers and/or switch channels on those amps. Once you have all the Banks programmed, we recommend placing a piece of scotch or electrical tape over each DIP (….just to protect the switch from accidental switching, damage or floods….like beer). There is a buffered (or not….switchable) Mono input and a stereo Output, and the unit is powered by dual 9v batteries, or by a regulated power supply…like the PowerJack or the Pro Power (both by Carl Martin).

Octa-Switch MK3

Welcome to the Classic Optical Compressor: a 100% analog old-school compressor from the days where colouring was an important factor to the sound. The four controls (from left to right) are the Gain, which controls the ‘pre-glow’ of the optical circuit (the more you turn this up, the fatter the sound); Level, which controls the overall volume of the compressor; Compression, which controls how hard or soft the compression is, and the Attack control which takes the signal from transparent to outright total squeeze. A short time with this compressor will allow you to find some of those classic guitar sounds which may somehow have escaped you before.

Der Bass Chorus ist das erste Gerät in Carl Martins neuer Reihe von Bass-Effekten. Obwohl er in seiner Funktion dem älteren Chorus XII ähnelt, ist er in einem neuen, breiteren/geringeren Metallgehäuse mit „Hühnerkopf-Knöpfen“ zur Einstellung untergebracht. Natürlich bleibt die Qualität die gleiche, und das neue Gehäuse umschließt auch die geregelte +/-12-V-Stromversorgung für maximalen Headroom und Klarheit.
Warum also einen speziellen Chorus nur für Bässe entwickeln? Die meisten Chorus-Effekte auf dem Markt sind für den Einsatz mit Gitarren konzipiert und daher im mittleren Frequenzbereich angesiedelt. Der Bass Chorus wurde umfangreich feinabgestimmt, so dass die volle Wirkung des Chorus bis in die tiefen B-Lagen zu hören ist.
Wie sein Vorgänger ist auch der Bass Chorus ein Dual-Stereo-Effektpedal mit unabhängigen Reglern für Geschwindigkeit und Tiefe. Mit dem Select„-Knopf kann man den Effekt ein- oder ausschalten und mit dem On“-Knopf kann man zwischen den beiden Chorus-Einstellungen wählen. Eine LED zeigt an, dass der Effekt eingeschaltet ist, und jeder Chorus hat seine eigene LED-Anzeige, die je nach Geschwindigkeitseinstellung blinkt. Ein zusätzliches Feature des Bass Chorus ist, dass beim Umschalten von einem langsamen Chorus zu einem schnelleren Chorus der Effekt langsam beschleunigt wird, um einen fetten Vintage Leslie-Effekt zu erzielen!
Der Bass Chorus ist die einzige Wahl für Bassisten, wenn man die Funktionen vergleicht...

The Bass Chorus is the first in Carl Martin’s new line of bass effects. Although similar in function to the older Chorus XII, it is housed in the new wider/lower metal housing with ‘chicken-head knobs’ for adjustment. Of course, the quality remains the same, and the new housing also encloses the regulated +/-12V power supply for maximum headroom and clarity.
So why design a special chorus just for bass? Most chorus effects in the marketplace are designed for guitar use and therefore are mid-range heavy. The Bass Chorus has been extensively fine-tuned so that the full effect of the chorus is evident as far down as low B.
Like its’ predecessor, the Bass Chorus is a dual stereo effects pedal with independent sets of speed and depth controls. The ‘Select’ button allows you to use or bypass the effect and the ‘On’ button allows you to choose between your two chorus settings. There is an LED to show the effect is on, and each chorus has its’ own LED indicator which flashes at the speed setting. An added feature with the Bass Chorus is found when switching from a slow chorus to a faster chorus, the effect speeds up slowly for that ‘phat’ vintage Leslie effect!
The Bass Chorus is the only choice for bass artists when you compare features…
