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

So you wanna build a Dumble Overdrive Special?

The Dumble Overdrive Special has been one of the "Holy Grail" guitar amps for many years. So what are the chances of you getting your paws on one? It is thought that there may only be around 300 original Dumble amplifers in existance with the asking price now from $20,000 - $50,000! That's probably not an option for most of us, so what can we do for that Dumble tone? Well, we'll make our own won't we :-)

Here's a great clip of an original Dumble Overdrive Special in action:

There are quite a few kits out and about these days, one of the most widely known and reviewed as "the best" is the Ceriatone Overtone Special which can be found here: http://www.ceriatone.com/productSubPages/OTS%20Series/OTSMain.htm

Here's a layout for the Overtone Special 50 (A Dumble Overdrive Special 50W Clone):

The Kits at Ceriatone are fairly well priced. Obviously if you can find your own suitable donor chasis you'll cheapen up the build considerably!

Here's a demo video of the Ceriatone Overtone Special in action:

They do sound pretty sweet, really smooth and break up so nicely with single coil pickups. If I had the cash I think I'd be going for a DIY Dumble build asap!

There are a great set of instruction videos on youtube created by Tony McKenzie which document his building of a Ceriatone Overtone HRM kit, here they are for you:

He's also reviewed the amp too, check out his site here: http://www.tonymckenzie.com/ceriatone_hrm_review.htm


  1. I am sure Ceriatone makes a great kit, the only issue with Ceriatone is that shipping will cost you a mint. The kit is 1255 with the head cabinet and weighs 44 Kg for all components. My guess is that with packaging you are closer to 50 Kg's total. The lowest price shipping charge they have for 50 KG's is $375 bucks which is nuts. Plus you will have to pay import duties on it as well. It is due to the fact they are in Malaysia, if Ceriatone really wants business to take off they should setup some sort of warehouse in the US to have his kits shipped out of the US.

  2. It appears as thought the heater wiring was red and black on this build... it's suppose to be green... people should stick to the accepted standards instead of their favorite color. It makes troubleshooting safer and easier.

  3. its been a few years since your post in 2014, but I checked with Ceriatone and they have a 'distributor' list. I called a couple of the distributors here in Massachusetts, and they didn't have Ceriaton'es on their web site, but did say they could get them, so they have some kind of deal.

  4. This would be a fun project from scratch. Chasis and all. Take the challenge to find the parts somewhat locally.
