Ruby / Noisy Cricket Mini Guitar Amp

Based on the magnificent work of RunOffGroove, the Ruby circuit can kick out some serious oomph depending on your choice of speaker. All from a little 9V battery or DC supply (can be supplied with 12V if you really want to push it).

Some clever jiggery-pokery over at Beavis Audio gave birth to a highly modded Ruby, dubbed the Noisy Cricket. This adds a tone control and a 'grit' switch to give it a little more break-up.

Will drive pretty much any speaker with different dynamics depending on size/impedence. A Marshall 4x12" goes from fairly loud clean to louder with decent break-up. A little 4" speaker went from crunchy to full-on screaming.

No enclosure option for this - half the fun is housing it. We've seen some crazy versions!

Kit includes: PCB, all components, hook-up wire, stereo jack socket, DC socket, battery snap. Output jack is optional. Noisy Cricket includes toggle switch. Does not include knobs.

OUCH
"Recently added a stripboard headphone circuit, which I highly recommend. Though be careful, because my ears got hammered into the centre of my brain. Maybe Lee could add this one day..? Still a great little amp which drives a variety of speakers I have, the bigger the better, believe it or not..." MICK JONES - 11 March 2017

Ideal for polite but distorted busking!
"I bought the circuit board only as I had most of the bits lying around. This is a great sounding little amp, and I've got a neat little ABS box for it. I always put pictures of these kits I build up in Facebook, and people are starting to ask me to fix things dammit! :-) ha! I love this amp, it's a good feeling, building something that works so well. Thanks Lee." Mick Jones - 04 September 2016

"I bought this to modify/power a voice box - from an OLD model made by BELL labs. It used to run between the amp output and speaker, so it had a massive resistor in it. Anyway, this thing works AMAZINGLY, especially because you have the gain/vol control so I can tune the voice box more than any commercial model you can buy. Good project and excellent amp!"
