Title: Boss DS-1 Synth Drive by (cough) JHS
Post by: AntKnee on July 11, 2014, 01:51:00 PM
Just got a DS-1 cheap and wanted to do some mods. The JHS synth drive makes some cool sounds. While I hate to bring up those infamous initials, I have to ask: Does anyone knows how their DS-1 is modded? All I can find is Keeley mods.

Thank you!
Looks like that is probably it.
If anyone has any further tips regarding the DS-1 mods in the wampler book, please do share.
Thanks again!

After comparing the youtube clips of what I assume are the wampler book mods with the JHS mods, it sounds like the JHS mods are a bit different, and more usable. I haven't actually started any mods yet, but if anyone could check the clips and offer suggestions, I'd appreciate it.

I've got a PDF of Wampler's mod book. Pm me your email and I can extract the pages and send them over to you later.

Thanks, I have the pdf. I was just wondering if they were the same as the JHS mods. I know the only comparison available is youtube clips. I doubt he is open about what he does to his mods.

I think JHS uses a transistor between the same 2 pads that Wampler does

The third leg of the transistor I assume would go to ground then?
Now to find a suitable transistor...

I believe I read somewhere it was a bs170 or something similar.

I tried the synth mods on a DS-1 from the wampler pdf's, and didn't find any useful tones. It was very muddy and didn't track well. The JHS mods are most likely different.

From what I heard on the youtube clips, I thought that was the case. The wampler mods just didnt sound usable. The link to FSB above has what looks like actual JHS mods, but I havent tried them yet.

If you like that, you'll love an UglyFace. It just does the nasty side of that.

Holy.
Crap.
You're right. I must build that. Is Musicpcb the only place that has pcb's for it?

Found this:
http://www.madbeanpedals.com/forum/index.php?topic=10370.msg92500#msg92500

Is the LFO a seperate circuit, like two effects in one box, or is it an add on to musicpcb's board?

I've done a PCB of the uglyface with LFO ;)

Got 2 spares if anyone wants one?
