Product description

WHAT IS THE DR. ROBERT PEDAL?

The Dr. Robert is a guitar overdrive pedal based on the Normal channel of our Vox® UL730 S/N: 3042. This amp in a box pedal was designed to be the closest replica of the amp’s soul and character. A meticulous process of tracing the original tag board circuits and measuring each component’s value has resulted in a sonic approach never reached before.
 

DR. ROBERT PEDAL MAIN FEATURES


THE MOST ACCURATE REPLICA OF THE ORIGINAL UL730 PREAMP
Sometimes you can’t trust the internet or an old schematic! We’ve found major discrepancies between the published schematic and the real thing, such as component types and values, so we can assure this is the closest you can get to the rarest Vox amp!Following the preamp there’s a custom FET based circuit emulating the saturation produced by the UL730 EL84’s tube power amp section.Additionally, the circuit works with the same voltages found on the original amp thanks to a charge pump circuit which takes the 9VDC from the battery or DC plug and converts it to 18VDC. 

SMART TRACK FASTENING SYSTEM
All our pedals use a custom enclosure designed to match perfectly our Smart Track pedalboards. Using the side thumb screws, you’ll be able to lock safely the stompbox into one of our pedalboards. It also was designed with the other pedalboard options in the market in mind. 

MACH SCHAU! FUNCTION
Extra saturation function via a footswitch with an independent volume control. Hit it when the venue’s manager wants you to play harder!

CUSTOM GRAPHICS BY REVOLVER'S COVER ARTIST, KLAUS VOORMAN:
We’re so honored to have Mr. Klaus Voormann, designer of The Beatle’s Revolver album cover, sign the artwork for the Dr. Robert! 




HIGH END COMPONENTS AND TRUE BYPASS SWITCHING:
We made an extra effort to put the finest and closest components to the original amp on the Dr. Robert. Carbon comp resistors, Nichicon Fine Gold and Wima caps, Alpha pots and switches makes the Dr. Robert a reliable pedal with a superb tone. 




CIRCUIT TAILORED FOR BOTH GUITAR AND BASS INSTRUMENTS:
Although based on the UL730 preamp, the UL400 series (designed for bass) shared almost the same circuitry. When doing tests using different instruments and amps we noticed the Dr. Robert sounded flawless with bass too! By tuning the FET circuit a bit, we managed to make the Dr. Robert suitable for both guitar and bass. No low-end drops resulting in a prefect preamp and distortion tool to plug directly to the desk or into an amp.
 
INTERNAL CONTROLS

The original UL730 VOx amp had a 3 band eq, but since the Middle control is the one that helps to tailor the tone better, there is a Bass and Treble controls inside the pedal.
