Welcome to the Revolution

Hi there, welcome to my blog - La Revolution Deux. It's an odd name - but I like it! Here you will find all the info on my various DIY Guitar effects builds, amplifiers and guitars. Everything from a humble Ibanez tubescreamer to the holiest KLON Overdrive.

You may also find a few effects builds that I am looking to move on - usually in exchange for other effects/gear/cash. You can always check my ebay account to see what I've got up for grabs.

Have fun, enjoy the blog - Fred Briggs :-)

Maxon / Ibanez - Super Tube Screamer ST-9


This was one of my all time favourite pedals - the *harder to find than hen's teeth* Super Tube Screamer ST-9. I had it stolen many years ago and I've been looking out for a replacement ever since! But, no need now - the schematic is available thanks to the wonderous Dirk Hendrik :-D So we can all build ourselves one of these super rare beasts.

So what is the ST-9? It's basically an Ibanez 9 Series Tube Screamer with a "Mid Boost" control up in front.

Here's a demo video of the ST-9 in action;


Here's the schematic from Dirk;



And here's a PCB layout for it by Boris; https://docs.google.com/open?id=0BwMWxzd7lEJ4aDd1V2V4cEJibW8

Along with a hand sketched layout file (It's clear enough if you download it);


I would recommend this build to anyone who like Tube Screamer type overdrives - it's an absolute little cracker! For those of you who do attempt a build here's the freestompboxes.org forum topic which includes some useful info for you: http://freestompboxes.org/viewtopic.php?f=1&t=3536


*Note* - A lot of people mix the Super Tube Screamer ST-9 with the "STL Super Tube" which was a later spin off of the ST-9! Here's the "STL Super Tube";

The Ibanez Super Tube - not the same as the ST-9!


The STL Super Tube is almost the same electronically as the the ST-9, the only major difference being that the Mid Boost control is placed after the clipping stage rather than before it. Here's a schematic for the STL Super Tube;


Both pedals sound good and are certainly worth a build!

  1. Great post. As an alternative you could check out the Ibanez Jet Driver. Rumors are that it's 1 for 1.
