This little amp has turned out to be one of my favourite builds. It's simple, ridiculously cheap to make, and the sound it gets out of two LM386 chips is pretty wild.
Thanks so much for supporting what I do, it really does help keep these projects coming!
I'm putting the finishing touches on the video now, including a bunch of different tones, and I'm seriously stoked with how this little quarter-watt monster sounds. It's taking a little longer than planned, but it's coming this week!
Here's a useful bonus if you're planning to build one: all the mods for the original Dumbleton will work with the VH-ONE too!
So if you've already picked up the Dumbleton schematic through a previous purchase, you've already got those mods ready to go.
If you haven't got it yet, you can find the schematic and mods here:

And of course, I'll be doing a deeper members-only dive into the VH-ONE circuit to go along with the main video.
Nearly there! Can't wait to share this one with you all. 🤘
Here's a little preview of what's coming to YouTube in a couple of weeks.
After the ridiculous success of the Dumbleton, I wanted to take the same sort of unconventional approach in a completely different direction.
This one is designed from scratch, built on a block of wood, and uses two chips to chase that classic high-gain rock sound.
It's only a quarter-watt, but it drives a real 8Ω or 16Ω guitar cabinet, and the sound is genuinely ridiculous.
The full video is coming soon, along with a Workbench Tier members-only deep dive into the circuit, the design decisions and how the whole thing works.
More soon. 🤘

I've been wanting to find a simple way of explaining what actually happens to a guitar signal as it moves through pedals and, especially, through the different stages of an amplifier.
Check out the video here:
So I built an app to visualise it, and then made a video around it.
It's deliberately simple, but I think it could be really useful if you've ever wondered why your gear behaves the way it does.
