When a client approached me to silence his Tonehammer amp I took on the task. Here is the short story what we did. There are two cheap fans 50x50x10mm used in the stock amp. Although they are not super noisy but due to their size and rpm needed they make an annoying pitched noise. This […]

This is the story of how this handy tool came into existence. Once upon a time there was a pedal builder soldering effect circuit after effect circuit. Most of the builds were running out of the box – soldering finished, guitar to in – amp to out – there was noise! But occassionaly there were […]
It started as an improved version of the EPIC Looper and due to serious time restictions it could not be brought to an end 4 years ago. Recently things changed and we revisited the project and found it still an unmatched and high-end DIY project for every experienced builder. It took two month to build […]
Since we have already built the audio switching part in the first chapter, we now do the microcontroller. In the beginning of the project there were several options on the display that can be used but due to the restricted time at hand the version with the OLED display most complete. They come in 1.3″ […]

In the music environment nothing can be done without EQs! This starts with simple tone control and ends in the endeavour to simulate complex loudspeaker cabinets. 5-band graphic eq This one is using a special chip to reduce parts count and therefore space. It could also be done using OpAmps but I […]

About the circuit Jon Patton is a great engineer in building guitar effects. He developed a good number of circuits that are well known in the DIY community. What Jon sais about this circuit: This was a fun challenge, and it came together pretty quickly once we identified what would work well with his amp […]

The TH custom line of quiet switching Seriously: Everyone owns a pedal that sounds great but makes problems when switching it on and off. The reasons for this can be found in the “To popp or not to popp” knowledgbase-article. The other issue is the mechanical endurance of the switch itself. How long will it […]

About this circuit Merlin Blencowe, also known as the Valvewizard (http://www.valvewizard.co.uk), introduces his new circuit on his projects page as follows: Jenny GreenTeeth started off as an experiment in making a chorus effect using the PT2399. Chorus is created by passing the signal through a very short delay line, somewhere between about 8ms and 25ms. […]

[wpdm_file id=76] This is based on a DOD 250™/ MXR Dist+ overdrive which is a straight-to-the point distortion unit. In addition to that Brian Wampler has written a nice article in premierguitars which discussed a lot of modifications to optimize the circuit http://www.premierguitar.com/articles/mxr-distortion-plus-mods-1 Those mods are switchable on the OD67 board. The most usefull one […]
