The "Tesseract" DIY Guitar Practice Amplifier is a DIY 0.5W guitar amplifier designed using - and built on a PCB supplied by -*https://EasyEDA.com. It runs from a 9V battery with a selectable junction FET or bipolar transistor input stage, adjustable distortion, an adjustable full wave rectification effect called "Wreckage", a simple mixer between the two effects and an LM386 power amplifier with volume and a selectable, adjustable high cut or high boost tone control.*
On/off switching is via the input jack and there is also a headphone output jack that disconnects the speaker output.

The design looks interesting. But, if anyone directly involved with the creation of the Tesseract is reading this, I cannot stress enough how important it is to demo the amp using someone who can actually play a guitar.
Without that, there is no way for the observer to judge whether this fairly complex amp sounds good, and is therefore worth building.
With all due respect, the You Tube video linked on the project page is far and away the worst demo I have ever encountered for any piece of guitar gear. Beating on the open strings of a guitar with a pencil (??) simply makes a series of horrible noises, so it is quite impossible to tell if the Tesseract amp itself is good, bad, or indifferent. We need to hear actual music played through it, by an actual guitar player.

Frank Zappa played a bicycle with drumsticks on national television, after all. 🙂
(He sounded utterly awful too, at least to my plebian ears. 😀 )
