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

Lovepedal - Delux 60 Mosfet

These things are RARE. It's a Lovepedal Delux 60 Mosfet - they were also sold in a dual format known as the "Twin 60". Greg from the Freestompboxes.org forum bought one and opened it up - here's what he found:

He drew up a quick schematic too and kindly gave me permission to use it (Cheers Greg!):

Don't even ask me what that 47k resistor is doing in parallel to the 100k volume control - I know, it makes no sense. I'll quote Greg on this one:

"An observation. I think Sean has tried to set the .1uF - 47K High Pass filter on the output of the Mosfet so that it keeps guitar frequencies intact. Theoretically it would be 34Hz. But, considering the Volume pot is in parallel with the 47K the filter is actually set higher than he probably intended."

Maybe he did mean it? He also goes on to make the point that if you connected the Karl fuzz directly after this the high pass filter would jump to 370Hz (Due to the 5k pot on the Karl's input..). Hmmm, probably not great!
