Vahlbruch Sapphire Drive
Since the Vahlbruch "Jewel Drive" is more a so-called "medium-gain" overdrive pedal, the "Sapphire Drive" offers higher gain/distortion sounds.
It´s still a very open sounding pedal with a great transparency, also the 6 knobs are closely related to the "Jewel Drive".
The "Sapphire Drive" is a pure 100% analog hand-built two channel distortion effect pedal, especially designed to offer you authentic
tube overdriven amp sounds ranging from sparkling clean to moderate crunch to more distorted sounds. This pedal is extremely open sounding with high transparency and wide dynamics. The "Sapphire Drive" reacts extraordinary touch sensitive, the differences between softer and harder picking are reproduced in every nuances. Due to it´s novel and unique analog circuit, the "Sapphire Drive" creates a rich, complex and beautiful singing overtone texture, while the inherent tone of your amp and guitar you are playing is perfectly preserved.
Used as on overdrive in front of your amp the "Sapphire Drive" gives you the feeling of a cranked amp even at lower volume levels. Clean notes now have a wider dynamic range and more overdriven sounds are still pronaunced and rich with the right content of even-order harmonics. By simply turning the guitar´s volume knob you can blend through the complete overdrive spectrum, the "Sapphire Drive" interacts very, very well, very similar to a good tube amp!
Basically you have the common overdrive controls to adjust your tone: Drive, Tone and Volume. But there is an additional "Character" control which makes this pedal again unique. Turning this knob influences some dedicated electronic parameters inside the pedal at the same time. The midrange spectrum, the overtone structure, the dynamic and frequency response can be adjusted to perfectly suit your personal tone!
And this is realized by only ONE "Character" control and not many confusing switches and knobs.
And the greatest thing is that you have an additional foot-switchable and adjustable Gain AND Volume Boost, e.g. for solo work, which makes this pedal so versatile.
