Vahlbruch Quantum Opto Compressor/Sustainer & Buffer Pedal

One of our friends/customers bought his pedal board in to try some guitars earlier this year. He has over 300 pedals in his collection so we knew how much thought and process had gone into it. On the board was a Sapphire Drive but we weren't aware of Vahlbruch Pedals. We heard it and were completely blown away with the tone, transparency and versatility - it's handbuilt in Germany so of course the build quality is superb. We contacted Henning Vahlbruch and ordered another one of his pedals hoping that it was of the same quality - a Spacetime Delay. Lets just say it's the best delay pedal we have ever heard! We now carry almost the full range of pedals in store, many of which feature on our own WG Pedal Board.

All of the pedals also feature Vahlbruch's own silent switching technology called MagTraB.

The advantages of MagTraB:
MapTraB buttons are as good as indestructible! MagTraB delivers an almost infinite number of switching cycles - many, many millions!
No annoying, mechanical switch clicks! Instead, the MagTraB push-buttons switch very smooth and silently!

The "Quantum" is a 100% analog compressor / sustainer pedal on studio level with very easy handling. The core is a photocell, which generates a very musical optical compression. The pedal helps your guitar to cut through the mix without losing the instruments transparency. Especially due to the switchable parallel compression, attack and punchyness are fully preserved, only sustain is added without any tone coloration. Via a toggle switch also classic serial compression can be selected. A LED indicates the dynamic processing by its brightness. Internally the "Quantum" can be switched from "true bypass" to "buffered bypass". Used at the beginning of the signal chain the "buffered bypass" mode ensures a clear guitar tone even through long cables and effect chains. Another LED indicates the activated buffer mode as "Bypass Buffer On".
Buffer and compressor: "Quantum" is a 2-in-1 pedal! An absolute secret weapon and an "always on" pedal!
The "Quantum" is also perfectly suited for bass and acoustic guitar!

This pedal is equipped with our unique "MagTraB" switching technology:
Inside the button a magnet is integrated which position is measured by a sensor on the circuit board. If the button is now moved, e.g. if it is pressed downwards, the position of the magnet will also change. The sensor measures this change without any mechanical contact to the button and the information is send via a micro-controller to a gold-plated relay, which then does the actual audio signal switching.}

You can choose if the pedal powers up in "on" or "bypass" state.
To change the state:
Step 1: Unplug the power supply cable.
Step 2: Hold down on/off "MagTraB" button.
Step 3: Plug in again the power supply cable.
Step 4: Release on/off "MagTraB"" button.
DONE! The next time your pedal powers up it will automatically start in the other state.
