PreDrive Studio - Pettyjohn Electronics
The Studio version of the PreDrive.
The PreDrive Studio blurs the lines between high-end recording studio gear and guitar pedals, expanding on the popular “studio” features of the original PreDrive, improving it’s usability and flexibility that will make the PreDrive Studio an in-valuable tool for tone in every studio session!
Powered by two Studio Grade Discrete Opamps, the PreDrive Studio builds on the original PreDrive and LIFT pedal offerings, now featuring even more gain on tap, extended filter range, high headroom, dual power rail design with 9V-18V standard pedal power operation and a whole slew of circuit optimizations along with improved, robust construction. Most notably, The PreDrive Studio now offers fully balanced In and Out connections via TRS, along with standard un-balanced connections for instruments, making the PreDrive Studio the ultimate studio Swiss army knife. The PreDrive Studio Input can be selected as standard unbalanced for instruments or switched to a line level balanced input that readily excepts any balanced signal from your interface, patch bay, recording console, or even microphone! The balanced output continuously mirrors the unbalanced output without any tonal change, very handy in a number of creative studio applications. With the PreDrive Studio, you can easily and seamlessly interface between the unbalanced world of instruments and pedals and the balanced world of recording equipment. The PreDrive can be used as a powerful and flexible re-amping tool, however, the options only start there with many more to choose from! You can easily interface a variety of guitar pedals into your mixing path, process line or microphone signals with pedals without quality degradation, re-amp or simply use it as a audiophile grade direct box.
Shape your signal to perfection, in real time with the PreDrive Studio’s two highly musical, fully analog, wide-range, sweepable HP and LP filters. Much care has gone into the design and implementation of the filters and you would be hard-pressed to find more musical or transparent filters on any recording console or rack unit around!
What are all the features without an un-compromising commitment to sound quality? We designed the PreDrive Version 2 Studio to be a serious studio-grade, Tool for Tone with top-shelf 990 style Discrete Opamps, based on the famed John Hardy 990 chip. These discrete opamps are widely regarded as some of the best sounding, most detailed and transparent, yet still musical chips in the world. Drawing on knowledge pioneered by the worlds first discrete Opamp based guitar pedal, the Original PreDrive , we have totally re-designed and optimized the buffer and gain circuits in the PreDrive Studio with dual voltage rails for up to 2x the headroom for massive headroom and huge tone. Furthermore, we have utilized only top shelf audiophile parts to help deliver every once of sonic bliss these chips can produce! From the tone capacitors to the resistors, every part has gone under the microscope and has been optimized for maximum fidelity so you can be confident there isn’t a more detailed or musical buffer/boost preamp or EQ on the market today!
The PreDrive Studio can run on 9v-18v DC, drawing around 50mA, while effectively providing 18v to 36v of internal voltage swing, rivaling headroom found in most studio rack gear, translating to extra headroom for a truly studio-grade experience.
When we set out to create a new PreDrive we knew it had to be better in every way then the original, a seriously tall task. We believe the PreDrive Studio is the absolute pinnacle of studio grade guitar pedals, virtually erasing the line between the pro audio gear and guitar pedals.
