Re: onboard usb charging for onboard efx

Let me revive this thread to help me understand one thing. I'm myself about to update one instrument I built with a socket (more likely a standard DC jack rather than USB) for charging a standard 9V rechargeable battery that powers the preamp (the way I built it makes getting the battery out a pain)...

Re: Piotr Sell's Electric Upright Bass

Thanks! I'm glad You like it. I hope the process of development of the design I described here might be of some use for others working also on different projects. In my opinion it's much better to take your time and refine the design before you get to the actual building and sometimes the "test...

Re: Piotr Sell's Electric Upright Bass

An important image that was missing is one of the bass in action! Here you can see Simon jamming: dsdv3bass_22.jpg At some point I will also post here some sound samples or videos. My 'dirty' workshop secrets are already revealed so If anyone would like to know anything more I'd be happy to answer a...

Re: Piotr Sell's Electric Upright Bass

Here you can see it together with the other pieces right before spraying first coat of primer. You might notice there are pieces of wood at both ends that allowed me to set the threaded inserts. Well, I know it doesn't appear overly impressive in this state. I have to say that even though one can sh...

Re: Piotr Sell's Electric Upright Bass

The before mentioned second stage ended with the basss looking like this: dsdv3bass_17.jpg Note that even though I spray painted the model of the 'strip' I wasn't even close of being ready for molding. You might also noice that its both ends weren't yet defined precisely. I left that for the final s...

Re: Piotr Sell's Electric Upright Bass

I'm back with few more photos dug from my archive and hopefully more story to tell. Like I mentioned at the beginning, this instrument has a clean look but it has been achieved the dirty way. Often limited to long hours of patient sanding. I did the whole thing "my" way rather than the &qu...

Re: Piotr Sell's Electric Upright Bass

Have a look at this picture. It should make more evident that the 'strip' is integrated with a sort of skateboard-shaped back plate of the bass. This pack plate is bolted onto the bass and has the end-pin mounted inside. Originally, instead of bolts I planned on using some "quick release" ...

Re: Piotr Sell's Electric Upright Bass

Before I get to explain how the 'Strip' works and how it was made, here you can see the prototype design that developed into the instrument you can see in the photos above. I also built this prototype which allowed to verify that my design really works. As you can assume I got confident enough to tw...

Re: Piotr Sell's Electric Upright Bass

Thank You for all kind words and interest! Here are a couple more close up pictures to explain some of the details: Headstock It looks like a standard EUB headstock and so it is, but figuring out things like strings' break angles wasn't that straightforward. A great reference to understand how it sh...

Re: Piotr Sell's Electric Upright Bass

I forgot to officially thank the photographer Kuba Styperek (Strike-Photo) for shooting those great photos of the bass. Thanks Kuba! without you the world wouldn't get to see this instrument

Piotr Sell's Electric Upright Bass

Hello everyone, After a long absence I would like to share a project that I completed last week. It is an Electric Upright Bass, it is my third instrument and it took me almost four years to design and build it. Compared to my previous projects it was a rather daring challenge considering I wanted t...
