Build A CBG Amplifier

You do not need to be an electronics wizard to build a CBG amplifier*.  A few items from your local electronics supply store, and a little patience and time is all that is necessary.

Materials

• 1/4" input jack for guitar signal (1).
• Headphone jack (stereo connect left and right channel)  (1).
• 9-volt battery terminal connector and 9-volt battery (1 each).  Velcro works well to keep the battery secure in the box.
• Capacitors (1 each):  10uF; 220uF; 0.1uF.
• 10 ohm resistor (1).
• LM386 op amp (1).
• 8 ohm speaker (1).
• 8-pin IC base (optional).
• SPST switch (optional) the battery will last longer if used.
• Perfboard of choice.

You can go bonkers with the use of a box, but a small 'fat' cigar box works well.
