Vahlbruch Quantum: Opto Compressor/Sustainer + Buffer Pedal
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".
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. The advantages of "MagTraB" footswitches:
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.
