Troy van Leeuwen (TVL) Octavia and RAVEN

“Dr. No collaborates with Troy van Leeuwen on a range of two unique signature tone guitar effects.”

The Collaboration between Troy van Leeuwen and Dr. No started after a gig in Amsterdam, were Troy van Leeuwen was playing with Iggy Pop’s Post Pop Depression in may 2016. Troy van Leeuwen, (known from the Queens of the Stone Age, Failure, Sweethead, and his recently formed band Gone is Gone), asked Dr. No if he would be interested in doing a project with him.

Totally unprepared for this question, but as a great fan, honoured by the request, Dr. No leaves the venue and after missing his last train back, and so a long night stay at the train station, he returned to his laboratory to immediately start to outline the ideas TVL had put in his head.

It wasn’t an easy job to evolve in previous designs and sonic concept and take this to a next level as well as to capture the artist in question’s DNA and put this all in a guitar pedal.

After a long search and a few prototypes, Dr. No came to the conclusion that Troy’s wish list wasn’t able to fit in one pedal. Soon the idea came to create the whole enquired spectrum of unorthodox tones, in two enclosures and two different concepts. To be honest the signature QOTSA was a guide line as Troy van Leeuwen told Dr. No some of his sonic secrets to capture in this project.

So, not one but two pedals for this connoisseur were going to be developed.
First up is the Octavia ( not to be mistaken by an Octaver), if you listened to Jimi Hendrix and his solo at the end of “Who Knows” in “Band Of Gypsys” as well as many QOTSA riffs and songs know what an Octavia is. This Octavia is made with two functions. A “Blameshifter” (inside QOTSA joke) switch to set the gain of the Octavia, getting a nasty to sweet Fuzz tone, and a overall Volume knob.

The Octavia works best when put first is a pedal chain, try to work with guitar tone knob, when dailed back, magic octavia tones will come out better, especially from 12th fret and up.

The RAVEN completes the serie, that together with the TVL Octavia, that has been developed over the past nine months in collaboration with Queens of the Stone Age member Troy van Leeuwen.


The RAVEN contains a filter and booster effect that can work separately as well as together.


Functions Filter:
(RAVEN Skull knob) Capacitor switch for three different ranges.
“Q” range potentiometer for filter Q.

Functions Booster:
Volume boost knob.

A special “TVL” Crest is designed and added to the cosmetic design on both pedals top design as well as used on the wax stamp on the front side of the pedal.

The TVL RAVEN and Octavia are used on the new QOTSA record “VILLAINS” that will be released soon.

The complete design and techniques are fully handmade and feature only custom made elements especially created for this “TVL” signature collaboration effects.

Because this particular pedal consumes a lot of time and work in custom made elements to build, only a few per month will be available at this labshop and listed dealers.

Troy van Leeuwen and Dr.No started a collaboration!!!

After very successful collaborations with Alain Johannes and David Catching, Troy van Leeuwen (Queens of the Stone Age, Gone is Gone, Sweethead, Iggy Pop), started a collaboration with Dr.No. Troy and Dr.No started developing a three piece of exclusive guitar effects, custom made by Dr.No in collaboration with Troy van Leeuwen.
As being a gear addict and always on the search for new inspiring tones and with many signature models on his name, working with Troy van Leeuwen is going to be a true challenge. The pedal range is going to feature more art, new sounds, great analog tone. More soon!
