Vemuram - Jan Ray Overdrive

So, if you've heard of the Japanese pedal company Vemuram you've probably heard about this: Vemuram Jan Ray = Timmy Clone. It's an attractive pedal - nice brass enclosure, vintage looking knobs. Check it out in action here against the Timmy (yes, there are slight differences - the treble control has a different range and the OPAMP chip is different but the circuit structure is exactly the same.);

Now, the Timmy (the original which is made by Paul C and has been since 1997) has been cloned several times in the past by many different manufacturers. Off the top of my head there's the Danelectro Cool Cat Transparent Overdrive and the Lovepedal OD11.

Well we have mmolteratx to thank for discovering this latest example of boutiquer cloning. He picked one up and gutted it before tracing it out and providing a schematic for us;

And here's the schematic he drew up;

Yeah, it's a Timmy with a slightly altered treble control. Here's an explanation from mmolteratx;

"No, it's entirely in the different treble control. The bass response is exactly the same, all the trimmer does is vary the effective value of R4, which sets the gain of the stage. The treble control on the Jan Ray lops off everything above 2.8kHz at -6dB/decade at max. The Timmy's control at minimum does the same, but at 10.6kHz. Just use the Timmy's control in a different range and you've got a Jan Ray."

So, there you have it, nothing new and yet another clone. For more information, and a great layout from IVIark (of tagboardeffects.blogspot.com) on the Vermuram Jan Ray Overdrive visit this; http://freestompboxes.org/viewtopic.php?f=7&t=21934
