Our first USOLDER kit, 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. Just check out our Customer Corner for some inspiration! We supply the guts and you supply the creativity!

Features include volume, tone, gain, MP3 input, headphone/ear bud output and a DC power input (adapter not included). 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. Also available as a NO SOLDER harness and complete kit including a 4.25" speaker.
