BUILD A TONE MONSTER!

Our first USOLDER kit and also available as a NO SOLDER harness, the MAC-3W features a PCB (Perforated Circuit Board), all components and parts to build your own 3 watt guitar amplifier. Unlike the preset gain of our best selling MAH-3 circuit, the MAC-3W has variable gain so you can go from clean to down right dirty and everything in between. We also added an MP3/IPOD input so you can play along with your favorite tunes. Truly a full-feature circuit, the MAC-3W's PCB is just 50 X 35 mm so you can install in a small enclosure, travel guitar, amp-in-case creation, cigar box guitar, etc. We supply the guts and you supply the creativity!

The circuit board is clearly labeled with each component making assembly straight forward. The MAC-3W not only teaches basic amplifier circuit design but helps build soldering skills.


The MAC3W is designed as a mini amp circuit for use with small (2-6") low wattage (3 up to 10 watt) 4 or 8 ohm speakers. If used with large high wattage guitar, PA, car audio or stereo speakers distorted sound, overheating and permanent damage to the circuit may result! The suggested DC power supply is 9 up to 12V 500mA center (+) fully regulated however battery power (9V or 8 AA 12V) is recommended. Due to the wired components (potentiometers, input/output jacks & LED) for install flexibility hum can be present when a DC power supply is used. Potentiometers are 6mm split shaft. Knobs are not included!

The MAH3 has all the bells & whistles to make your next guitar amplifier build the envy of all of your friends. With a full 3 watts of power, it features (3) levels of overdrive from sweet vintage tube to classic rock and all out metal mayhem! Loaded with our proprietary tone expander circuit which not only provides enhanced EQ control but a flat boost for tones that rival many full size guitar amplifiers. Powered by a 9V battery for complete portability or external power supply (not included), you can power multiple speakers for a classic twin build. Not to be confused with all those pint-sized 1 watt or less replicas of brand names amps collecting dust on your shelf, the MAH3 is a serious little TONEMONSTER!


This is not a "gut a no name mini amp and put it in a cigar box" but a custom designed amplifier circuit that will blow away all of those 1 watt replicas collecting dust on your shelf. Great for low level jamming, practice, busking and even for recording. Best of all it allows you to create a personal statement with your choice of the enclosure. From cigar boxes and vintage radios to custom built enclosures and lunches boxes, we always recommend that you "think outside the box" for a unique build!

The MAH5 is not just an upgraded version of our MAH3 circuit but a completely new design. To increase output, add functionality and keep the circuit board as small as possible, it required several prototypes to get it just right. The final result is a NO SOLDER solution that allows you to build an awesome mini amp in an hour or so with minimal tools required. With features like 5 watts of power, tone expander circuit, (4) levels of overdrive (Tube/Blues/Rock/Metal) and even an MP3/IPOD input, it is the ultimate NO SOLDER DIY guitar amplifier circuit.

If you want to build an amplifier for busking, low level jamming and even recording, look no further as the MAH5 is hands down your best choice. Install in a cigar box or other suitable enclosure for a rockin' mini combo amp. Use as a "head" to power various speaker enclosures or an effect pedal enclosure to create a POCKET MONSTER! The MAH5 takes the custom mini amp to the next level. You can build a personal statement that is functional and portable. Whether building an amp for yourself or for resale, the MAH5 will set your build apart from the rest!
