I have updated the AMZ button to work with Firefox version 10. It adds a small icon on your Firefox toolbar that will take you directly to the AMZ Guitar FX blog. I’ve tested it with several versions of Firefox, but you should be updated to the latest version for security purposes anyway.
Just install the button by clicking the link below, and then restart Firefox once it has been installed. You may need to position the icon on the toolbar when Firefox restarts. This is done by going to the Firefox menu selection of View/Toolbars/Customize. Find the AMZ-FX icon and drag it onto the toolbar in the position you want it to occupy… for example, next to the Home icon or down past the end of the location entry bar. Enjoy!

Arrived in the mail today. Are these Hammond boxes new? (more…)

Here is a prototype of my ATtiny development board, and a printout of a bypass pcb that can control 4 pedals.

Update: The parts needed for this project arrived and the pcb is populated and ready to test. The ssm2166 adapter is mounted in the socket on the right.

What makes this buffer board special is that the input has been designed to duplicate the input circuitry of the typical tube amp, and it thereby preserves the interaction between the guitar’s pickups and the buffer circuit. This makes the sound of the guitar more natural, with a similar resonant peak, while still providing a low impedance output drive for your cables and pedalboard.

I have added instructions to the relay bypass support page to show how to use it as an A/B box controller. Also added are instructions on using the relay board to switch the booster/buffer outputs of the
AMZ Mosfet Booster.

The Big Muff may be a classic distortion design, but it is often too much of a good thing. The cascaded gain stages with the dual diode clipping will remove most of the dynamic range from the sound. This article is about trimming down the basic design to give back some of the dynamics, enhance transparency and make the pedal a more useful and versatile distortion/overdrive.
