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 :-)

Toneczar Openhaus - Distortion and Overdrive



Anyhow - here is the latest offering from the wonderful freestompboxes.org - the ToneCzar Openhaus distortion. It's a pretty brutal distortion circuit (it's build complexity it pretty high too!) Here's a link to the ToneCzar Openhaus instruction manual: http://toneczar.com/downloads/features-openh.pdf

Here's a demo video:



Here's the schematic and parts list: http://www.mediafire.com/?e9etdzabx75miqk
and here's the PCB: http://www.mediafire.com/?f2ukijxi32qq5w4

Eeeeerrrrrm, how good is this - vero layout (Harald Sabro of www.sabrotone.com):

A massive thanks must go to abfackeln for this one!

Blackstone - Mosfet Overdrive


In the realms of solid state overdrive pedals a lot of contenders claim to be "tube like" and have that tone which only a true vacuum tube can provide. However, few actually deliver on that promise. After having played around with the Blackstone Appliances Mosfet Overdrive circuit I can safely say - it sounds damn good! Certainly tube like and very responsive. This is partially to do with the CMOS inverters found in the circuit design (Which is where the mosfets come in, within each inverter stage are two mosfets ;-) For those that were wondering) but is also partially to do with the interesting use of the front end opamp gain stage.

For anyone looking for a different tone than the standard tubescreamer I'd recommend you give one of these things a go! Check out the youtube demo, I love the tone;

Fred Briggs - Silver Orchid OD/Boost FOR SALE!

Update - Sorry it took this long to put up a SOLD notice, this one went in the first few hours!. I'm sorry if you emailed after it went! I'll be putting up some more of my builds in the future. They are all sold on a first-come-first-serve basis, I don't do auctions (unless the pedal is on ebay of course!).

Hello hello, I have one of these beauties for sale. It's all made up and ready to go, it's the one pictured. It's a low/medium gain OD/booster. Check out the instructions sheet image below for more info. It's a super dynamic pedal capable of tones from bright and light clean boost right through to a sturdy rock 'n roll bark. I'd like to keep it for myself but I need some cash for parts to build up a new mini amp :-) (1.5 Watt Plexi anyone?!)

I'm looking for £75 for this one (approx $125 or 85 euro) Shipping in the UK is £4, shipping to the US is $20 and to 7 euro to Europe. All shipping is first class and fully insured. Send me an email if you're interested/have any other questions :-)

Fred Briggs - Hummingbird Overdrive

Here's another one. I've had a lot of emails for this one. The best way I can describe it is as an "enhancer" - it makes and already good overdrive tone better! It produces a great low overdrive, the compression and shimmer controls are very interactive with regard to both the gain/clipping structure and the overall tone and feel of the device..

This design was born from a challenge set to me and a few others by Bjorn of BJF effects to build a circuit that sounded like the honeybee. Soulsonic came up with a very elegant and simple design called the Hunny Bunny: http://www.soulsonicfx.com/?page_id=88 (I love that circuit). The Humming Bird De'luxe is what I came up with and you can see the schematic below.



Here's a vero layout by Harald Sabro (http://www.sabrotone.com):


[NOTE] One of the capacitors is marked as 47k on the schematic - this should read 47n. Point B goes to the input of the mosfet stage.

Fred Briggs - Silver Orchid Overdrive

I've been away for a while. I'm back and here is a schematic for you! It's a great overdrive and boost, a development on from my standard overdrive. Add a switch to the diodes for extra fun :-)
