Greuter Audio Boost on Dallas Rangemaster -treble boosteriin pohjautuva boosteri, jonka soundin ytimenä on NOS-germaniumtransistori.
The Greuter Boost is based on the legendary Rangemaster Treble Booster. It boosts treble (actually upper mids) and makes your guitar sounds dirty with a slight overdrive. The Greuter Boost is no Clean Boost!. Cuts very well in the mix, pushes overtones into feedback. Works very well with cranked small low wattage tube amplifiers.
Great to reproduce the guitar tones of Eric Clapton (Beano and Cream), Jimmy Page, Jeff Beck, Ritchie Blackmore (early Deep Purple, Tony Iommi (early Black Sabbath), Marc Bolan (T-Rex), Brain May (Queen) and many more.
Hand built in Switzerland, true bypass, Switchcraft plugs, big knob, hand selected and biased NOS germanium transistor, NOS capacitors (Philips and Tropical Fish)
Since most of the germanium transistor are PNP and have positive ground, you usually are not able to use germanium pedals with normal 9V adapter. The Greuter Boost has an internal polarity converter to use it with normal 9V adapter. So there’s no hassle with using only batteries or a special power supply.
Volume: The more volume the more it overdrives
T&B: Tone switch to add more bass.
Works with 9V ac/dc adapter (negative tip) like 1Spot 9V adapter or Boss PSA 9V adapter (not included)
