YouTube recently changed the default settings for channels (including those that already had links enabled) so that social media links don’t show up on your channel banner. To enable these, here’s what you have to do.
1) Click the gear link under your channel banner
2) Enable “Customize the layout of your channel”
3) Add social media/website links as per before
Another IKEA hack, this time turning a single SNIGLAR changing table into two lower (and safer) ones by sawing the legs just above the second shelf:
I’ve been experimenting with some of the cheap class d amplifier boards available on eBay from china. This is the PAM8610 board with a Wampler Euphoria clone as a preamp. I added a footswitch that footswitches between clean and overdrive. It switches between two separate gain pots for clean and overdrive, removes the clipping diodes for clean, and adds a lead master in overdrive mode. I did some tests with this setup in separate enclosures, and there was very little hum, but as you can see from the video, there is tons when in the same enclosure. Maybe I have something poorly soldered, or maybe things are just too close together. Still it would be cool if a real manufacturer did something like this and sorted out all the issues because it doesn’t sound bad other than the hum. I might get another one of the boards and put it by itself in it’s own box. I’m powering it with a Mooer 2000mA power supply, but a one spot or anything over 1000mA should work, and it should take anything up to 12V.
Here’s some pics of the project. Notice I had to cut some of the plastic housing from the input jack, as well as bend the legs to make it all fit. The chassis is grounded, but the speaker output is isolated from the chassis. I kind of wish I’d used the deeper 1590BS instead of a 1590B so that there was a little more room.
After building a 2 in 1 overdrive, I’ve got interested in building more pedals, so here’s a few of the PCBs manufacturers I’ve found. Please let me know if you have more to add.
|BYOC||The classic kit shop|
|Aion Electronics||Large selection of PCBs with detailed analysis and history|
|Fuzz Dog||UK based, large selection of PCBs and kits|
|Delyk PCBs||Unique selection of PCBs including an effects tester|
|General Guitar Gadgets||Huge number of PCBs|
|Musik Ding||German based site|
|Arcadia Electronics||Good selection of PCBs with board mounted jacks and footswitch|
|Muzique||A few boost/drive PCBs|
|Jeds Peds||Another UK based company|
|MadBean Pedals||Another great site|

I had the idea that it might be more useful to have an overdrive with a contour control rather than a traditional tone control on it. I found this mid boost/cut circuit and added an overdrive section to it. It’s no the best sounding overdrive in the world, but here’s the schematic and a quick demo.
Just a couple of volume pedal ideas I had; To modify something like the Hotone volume/wah, and instead of having it manually switchable between a wah and volume, to use the built in footswitch to determine what mode its in.
1) The first idea I had was to have a volume pedal with a built in footswitch (like a wah). When you use the volume pedal normally its between 0 and unity gain. When you click the footswitch a boost is engaged.
2) The second idea I had was to have a volume pedal/expression pedal in one. It would have in/out jacks for the signal, then and additional TRS jack for expression. When you click the footswitch the pedal changes to become an expression pedal (and the audio signal just goes straight through).
