Matt circuit

Can be fitted into a packet of cigarettes, Also suitable as Fuzz-box This small amplifier was intended to be used in conjunction with an electric guitar to do some low power monitoring, mainly for practice, either via an incorporated small loudspeaker or headphones. The complete circuit, loudspeaker, batteries, input and output jacks can be encased in a small box having the dimensions of a packet of cigarettes, or it could be fitted also into a real packet of cigarettes like some ready-made units available on the market. This design can be used in three different ways: Loudspeaker amplifier: when powered by a 9V alkaline battery it can deliver about 1.5W peak output power to the incorporated loudspeaker. Headphone amplifier or low power loudspeaker amplifier: when powered by a 3V battery (2x1.5V cells) it can drive any headphone set type at a satisfactory output power level or deliver to the incorporated loudspeaker about 60mW of output power. This configuration is useful for saving ba...

Setting up an electric guitar is not rocket science, but it is something that a lot of guitarists shy away from. True, if you do this wrong, you can make your guitar play badly, but if you learn to do it right, you could save yourself a lot of cash. I should probably preface this by saying that today we are only going to do a basic setup. This is enough most of the time, but occasionally more is required, such as filing the nut, or doing some fretwork. If you want to set up a tremolo too, go to this post first: Setting Up or Adjusting a Stratocaster Tremolo Also, if you're setting up a Les-Paul-style guitar, you might prefer to have a look at this blog post: http://diystrat.blogspot.com/2012/09/how-to-set-up-gibson-les-paul-style.html So what does a basic setup involve? Let me break it down for you, as follows: 1. Checking and adjusting neck bow (how straight the neck is) 2. Checking and adjusting saddle height 3. Checking and adjusting the intonation (how far back or forward the s...

OK, let’s finish off our Cigar Box Guitar. If you haven’t already read parts one and two, they can be found here: http://diystrat.blogspot.com/2012/06/making-cigar-box-guitar-part-1.html and here: http://diystrat.blogspot.com/2012/07/making-cigar-box-guitar-part-2.html. I want to add some fret markers to the neck, but before that I want to fill in a few holes, as can be seen here: I glue in some toothpicks: Cut them and sand them down: It’s not a perfect colour match, but I think it gives it some personality. Now for marking the frets, I use an online calculator to determine the positions and mark them out with a pencil. There are many sites that provide fret calculators, but I used the one here and it worked great: http://www.tundraman.com/Guitars/FretCalc/index.php I should add here that since this will be a slide guitar only, we won't need any proper frets, just markers. Then I use a soldering iron to burn in the lines and the dots: We pretty much have a complete Cigar B...

Introduction Guitar amplifiers are always an fascinating challenge. The tone controls, gain & overload characteristics are individual, & the ideal combination varies from guitarist to the next, & from guitar to the next. There is no amp that satisfies everyone's requirements, & this offering is not expected to be an exception. The preamp is now at Revision-A, & although the whole schematic of the new version is not shown below, the essential characteristics are not changed - it still has the same tone control "stack" & other controls, but now has a second op amp to reduce output impedance & improve gain characteristics. One major difference from any "store bought" amplifier is that in case you build it yourself, you can alter things to fit your own needs. The ability to experiment is the key to this circuit, which is although introduced in complete form, there is every expectation that builders will make modifications to suit themselv...
