Looking for liquid sunshine schematic

Herr Masel · July 13, 2010, 06:55:54 AM

Hi, I haven't been here for a long time hehe.. I kinda got out of electronics, I've been playing the oud, got heavily into various middle-eastern music traditions. Anyway I've got the bug again, I want to build the liquid sunshine overdrive, I used to have the schematic but it's not online anymore. Has it been taken down on purpose because subdecay doesn't want it to be public anymore or if not can someone share it? I've found old vero layouts but you can only buy perfboard around where I live..

Thanks guys and gals.

Here you go: http://www.subdecay.com/images/schemlsv2.gif

Brian had to do a rebuild on the site a while ago and the old one got lost. This updated schematic shows both the original design and then the mods he later made to make them more consistent.

It's a really nice low to mid gain overdrive.

Excellent, thanks!

Question: if I leave out the part highlighted in red do I still connect the "bass" cap and pot to the last pot with the 100k resistor and "treble" cap?

No. It will oscillate like crazy if you do. I have a vero layout somewhere if you're interested.

Layout here if it's helpful: http://www.diystompboxes.com/smfforum/index.php?topic=72525.20

Thanks for the help, I ended up drawing my own perf layout on DIY layout creator, I'm building it now, if it works I'll share it.
Stupid question

(it's really been a long time since I touched a soldering iron), the 4.7 cap coming from Q3's source is 4.7uf or 4.7nf? I'm assuming nano, because that value in uf would make the cap polarized no?

Probably the schematic just odens't show that it's polarised- the -ve would just go to ground.

Hello, anyone has the schematic please? I think the link no longer exists.

I wonder where people get 2N5484 now? There are fakes on Aliexpress, and their production has long ceased.

InterFET still makes them and Mouser has almost 1700 in stock. They are a little expensive though.

What is the value of the pot going to the second JFET? The two final trnasistors are connected as a free-running multivibrator with the 4M7 feedback resistor taming the tendency to oscillate. It should give a nice overdrive sound as long as the FET gains are not high.

Here's a schematic that I traced from the Liquid Sunshine V2 layout at Dirtbox Layouts. I think its correct but feel free to check for yourself.
