Sunking Diode Test

[JakeFuzz]

Here it is. Sorry for the bad playing, just one of those days and not feeling it at all. Ran out of my 10 minutes before giving my opinions. The LM313H is the best sounding. The two germanium diodes (1n60 and 1n34) are much more clean, but have a fizziness to the breakup. The BAT41 and the LM313H are very similar with the BAT41 being quieter and more compressed sounding. The BAT46 sounds like the BAT41 but louder and cleaner. The LM's stay! As mentioned the Sunking uses NE5532P's in both positions, uses 6.8n instead of the 3.9n cap, nichicon micro audio grade capacitors, metal film caps in all but two positions and epcos box or panasonic films in the non-polar positions.

Hope this helps everyone out in there diode selections. Thanks Tubeman for the hot tip on these diodes they really do sound good.

Great demo!  I liked the LM313h the best, but the BAT46 was a close second IMHO.  Thanks for doing this

I couldn't tell much difference between the BAT41 and LM313h with my lil AKG headphones, but I assume it's more evident if you're in the room.  Anyway, I though they both sounded good.  Thanks for the demo!

Haha I was LITERALLY writing the same thing a few hours ago but had to lock my phone and forgot to hit Post!

Very cool demo Paul, thanks a lot! I do think the LMs sound best here

This is an awesome demo! The sunking really is a great sounding pedal. Personally I think all the diodes you tryed sound great and could be good candidates for this pedal!

great demo very helpfull


Really enjoy listen to Floyd Track

cool demo and nice playin

I swapped in two TL072's for the opamps and found that they sound better than the NE5532's! More sustain and an even attack response. I might just play around with more opamps to see what I can find.

Thanks, your demo's are awesome! Where do you buy the lm313h's?

[jtn191]

I bought some from Talon http://www.talonix.com/shop/item.aspx?itemid=8191
haven't tried em yet

[JakeFuzz]

Yeah I bought mine from Talon. You have to put a little dielectric material to separate the outer casings from shorts, the case is connected to one side of the P-N junction. I am amazed at how much the TL072's changed the sound, I like them much better. I will have to try 4558's maybe tomorrow.

so what'd you use to insulate it , Jake? And does the polarity of the LM313s matter?

Haha, you're going laugh but I just cut a small square from an index card and stuck it between them. I cut the leads pretty short so there was a lot of spring force between the two metal casings, enough to hold the card in by friction. If i had to do it again (or maybe I will in the future) I would use maybe a liquid rubberize (the stuff they use for tool handles) or heat shrink.

Yeah the polarity matters. It doesn't necessarily need to match the silkscreen but they should be facing the same direction (on the physical layout not the actual circuit). There should be a little tab denoting one end of the diode, just make sure those are facing in the same direction when you put them in.

 Thanks for the demo, the LM313H do sound really great and I was tempted to order some of them (especially since they are pretty cheap at Talon) but 19$ shipping to Austria? No, thank you.

Just swapped in some TLE2072's  . Best overdrive i've ever heard that isn't coming from an amp.

Also put a BB OPA2107 in my Timmy, amazing.
