The Ruby / Noisy Cricket Mini Guitar Amp is a compact amplifier based on the Run Off Groove Ruby / Beavis Audio Noisy Cricket circuit. It can be powered by a 9V battery or 9V DC supply (or 12V if desired). The Noisy Cricket version includes a tone control and a ‘grit’ switch for added break-up.The tone control may not be as effective as desired, so the recommended configuration is the Noisy Cricket without Tone. The grit control is highly recommended for added versatility.The amp can drive various speakers, with different dynamics depending on their size and impedance. For example, a Marshall 4×12′ speaker can go from clean to louder with break-up, while a small 4′ speaker can go from crunchy to full-on screaming.This new version of the amp is designed for board-mounted 9mm pots, allowing for more flexibility in enclosure layout. It is perfect for creating an amp-head style layout in a 1590B enclosure with room for a battery.If you prefer a simpler setup, you can choose the Ruby version, which only has Volume and Gain controls and no tone control. However, the Grit switch is still included.Please note that the board-mount 9mm pots have round shafts, so make sure to choose knobs that can be fixed with a set screw. The pot spacing is 18mm, so consider this when selecting knobs. Smaller knobs are recommended.The kit is also available with 16mm pots if you prefer to do your own enclosure layout and wire the pots to the PCB. However, please note that there is no enclosure option for the wired pots.If you choose an enclosure, it will be drilled to suit the options you have chosen.
