Inspired by Catalinbread’s Sabbra Cadabra, it features a two-circuit combination between a custom-tuned Rangemaster-based booster and the preamp section of the Tony Iommi’s Laney Supergroup. The outcome is a machine that delivers the greatest doom riffs; it’s like having Black Sabbath inside a box.
Sabbatical Drive delivers one of the most influential tones in the pantheon of rock by capturing the soul of the famous Tony Iommi’s Laney Supergroup amplifiers pushed by the Dallas Rangemaster treble booster. All of this is possible by changing the original tubes with modern JFET transistors.
The outside controls give you everything you need to dial in classic riffs or today’s doom. Its Volume 4, Presence and Gain controls will allow you to shape the dark tone of the Sabbatical. But the Range knob is the one that provides the most incredible diversity in tone: with it, you can mod the treble-boost section of the circuit, ending up anywhere from dedicated treble boost to full-range boost. This will grant you all the versatility you need, allowing you to access a high range of sounds to explore. Besides that, consider the effects your guitar’s onboard controls will have on the sound, providing even more realm for a creative approach.
