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 :-)


Feel free to get in contact with me about anything you see on this blog or with any general questions about guitars, amplifiers and effects, I'll be happy to answer! Just click the button above to email me directly or alternately my email address is fredbriggs2007 [at] googlemail [dot] com

Wampler - Pinnacle Distortion (Limited Edition)

The Wampler Pinnacle Distortion. This one has been requested - here's the details. Firstly a description from the Wampler Website:

"Zeke Clark, Edward Van Halen's longtime renowned guitar tech played through a pinnacle and this is what he had to say:
“I've played tons of pedals that promised that “Brown Sound”... this pedal NAILS it better than anything I've ever heard or played.”
-Zeke Clark, former tech for Eddie Van Halen

Sometimes you need extreme gain, sometimes you need mild overdrive...this pedal does that with an awesome “Brown Sound”! It has an extremely tweakable EQ - from scooped mids to tons of warm mids, all with the turn of 2 knobs.

This pedal has 4 knobs -- two separate tone controls that act as a sort of parametric EQ, gain and volume. It also has a 'bright' switch that adds a ton of variety and is very handy when playing a dark sounding amp, as well as another toggle switch that will give you high gain “Brown Sound” tones.

Pinnacle v. Pinnacle “deluxe”
The Pinnacle and Pinnacle Deluxe share the same great tone. The difference comes in the form of a couple special features found on the Deluxe version that make it more involved for us to make, but which add some extra versatility for you. While the standard Pinnacle has a toggle switch to control its Gain Boost, the Pinnacle Deluxe has that same functionality on a foot switch, so you can kick it in without having to bend down in the middle of a song. The only other difference is that the Pinnacle Deluxe has an additional, internal volume adjustment (just in case you need to go to “11” on the output volume). Because of the added switch, the Pinnacle Deluxe is a little bit larger than the standard Pinnacle, something to keep in mind if you're running a packed pedal board.

Which Pinnacle is right for you isn't a question of tone, because they both nail that coveted “Brown Sound”..! It just comes down to whether you need the special features found on the Pinnacle Deluxe, or prefer the smaller footprint of the standard Pinnacle."

And a demo video of the Pinnacle in action:

And here's the schematic for the Limited Edition version of the Pinnacle:

And here's another schematic, supposedly for the Pinnacle II:
Looking at the schematic you can see it's the basic dual micro booster circuit developed from the BSIAB II Diy circuit. They do sound good, give it a try. There's no layout yet but you can probably adapt the BSIAB II layout for use...

Here's the Freestompboxes.org forum topic: http://www.freestompboxes.org/viewtopic.php?f=7&t=14966


  1. I think, there is an unnecessary Grounding at SA1:1 of Pinnacle LE schem. Input goes either to out directly or it goes to the circuit. Grounding would inhibit the signal.

  2. That grounding is not attatched to the SA1:1 switch pole, it's suppously soldered to an individual pad i think. Yet, it's unnecessary

  3. the pinnacle diagram has an error. the 10k resistor that connects to pin 2 of the tone pot and goes down the page beside the vintage/modern switch should be shown jumping over the connection from the 4n7/switch/10k to the 47k that goes to the op amp. the pinnacle 2 diagram is correct here for reference.

  4. Hi all - working on making a board for the LE version. Can anyone verify that john w's comment above about the junction vs. jump is correct? Also, I wonder if pin 5 and pin 6 of the IC should really be connected by the wire that runs to the volume trim pot?
