The SD2W is our original guitar amplifier circuit and a great way to "get your feet wet" as a mini amp builder. With a robust 2.5 watts of power, it will give you the satisfaction of building your own guitar amplifier without emptying your wallet. Available as a circuit only (SD2WC), USOLDER kit (SD2WU) or a NO SOLDER harness (SD2WH), it features controllable gain so you can take your tone from clean to crunchy. Powered by a 9V battery for complete portability, just add a speaker and enclosure for a rockin' little custom guitar amplifier that you can be proud of. Also available in a complete kit with a high quality speaker and all of the necessary hardware to complete your build in a few hours with basic hand tools.

 Most customers use cigar boxes but you can "think outside the box" and install in creative enclosures. You are only limited by your imagination! Our amplifier harnesses have been used for amp-in-case builds, amp-in-guitar designs and just about any other instrument you'd like to install an on board amplifier. Build your guitar playing friends a custom mini amp as a gift. Start your own or add to an existing small business selling your builds at music festivals, fleas markets or on line.
