$50,000 tube preamp in a pedal

Blackbird tube tone engine

I’ve used a little artistic license with the title of this blog post, however be assured it is technically accurate and true – the Blackbird preamp pedal really is based on exactly the same tube circuitry and design ethos found in vintage custom tube amps that have exchanged hands for up to $50,000. These amps command hefty price tags because they’re a rare commodity, being bespoke, one-off creations built for … Read More →

Atomic Explosion in Tube Manufacturing Laboratory… in 1956

Sylvania explosion news

Okay I admit it! I’m an anorak and this post is strictly for anoraks. I’m fascinated with the history of vacuum tube manufacture and whilst trawling for more in-depth information on American tube manufacturer Sylvania I discovered an old copy of the St. Petersburg Times dated July 3rd 1956, which contained a fascinating news snippet about an explosion that occured in the Sylvania laboratory in New York. The story describes … Read More →

H1 Tube Signal Generator


After searching for many years I finally got lucky and managed to bag an Advance H1 sine/square wave oscillator/signal generator at a good price. The H1 is the exact same oscillator that BBC Radiophonic Workshop composer Delia Derbshire utilised to ‘play’ the melody to the original Doctor Who theme, which she arranged in 1963 – so not only do tubes make superb guitar amps and studio gear, they’re also good … Read More →

Merry Christmas from the Effectrode Team

Timberline Lodge in the snow

The picture above shows Timberline Lodge, which is nestled in the Cascade mountain range, Oregon just below the peak of Mount Hood. On an historical note, Effectrode pedals were manufactured in Corvallis, Oregon between 2004 and 2009 and I had a superb, almost panaromaic view of The Cascades from my office window on the fifth floor of Weniger Building at Oregon State University (my day job) – it was a … Read More →

Tesla Heritage: Are JJ Tubes the best modern tube manufacturer?

Tesla and JJ ECC83 compared

I’m always curious about getting the real story on the quality of modern manufacture tubes. Since the western tube manufacturing giants, Philips, Mullard, Tung-Sol, RCA, Sylvania and others ceased their production decades ago, today we’re left with just a handful of manufacturers, based in Russia, China and JJ Tubes in the Slovak Republic – the tube industry ain’t what it used to be. There’s no longer that vast pool of … Read More →

Phaseomatic vacuum tube phaser pedal

We’re fast approaching winter solstice and I wanted to get the artwork finalised for the new model Phaseomatic tube phaser effects pedal before the year is out. Here’s a nice shot of the Phaseomatic diecast aluminium enclosure fresh from painting and having the lettering silkscreened onto it. Star Trek fans migh notice I’m getting a little creative with my photography capturing some J.J. Abrams style lens flare from the winter … Read More →

Model PM-3A Phaseomatic Deluxe Update #2

Cardboard hole templates

Welcome to my wonderful world of research and development. The photo shows cardboard templates made from a ‘Weetabix’ cereal packet for hole cut-outs on the Phaseomatic phaser and Delta-Trem tremolo (yes, I’ve revised the prototype…Again) pedals. Both these effects have gone through extensive redesign and there’s a lot more to them, which is why they’ve taken so long to complete. We’re almost there though. It’s always a very exciting time … Read More →
