Neo Sholicon
As part of my ongoing downsizing I built myself a new Sholicon (Son of Sholicon) and a friend grabbed my old original Sholicon. However he was having issues so he sent it back. The prob was likely the PSU to be fair, but he preferred battery anyhow so I decided to add that.
Well one thing led to another and it's been re-built in a new enclosure. Mainly to get the battery in there snugly (mine was never made with it in mind and it didn't fit) and because it was a bit scruffy compared to a recent build (I am OCD Man). The PCB has come from JimmyBJJ once again. Cheers dude!

If you don't mind my asking, what is the Sholicon?

I'm gonna guess SHO feeding into a silicon ... bender.
Most excellent picture right there, John! nice knobbage, too.
Really nice mang!
T'other way around, but yep, it's a Hot Silicon with a SHO on the back.
Cool! Looks good
I populated the board for a Hot Silicon but never wired it up. How is it?
I love this build. It's actually one of my favorites that you've done. The graphic is fantastic, as is the wiring.

It's a great effect, gives a real Billy G vibe. The Sho on the back really thickens it up and gives it some punch. The only probs with the circuit is that it can be a tad noisy at the other end of the gain dial with the transistors that we use (Q1&2 2N3904, Q3 2N2222 and Q4 2N5088), but you never turn it that far anyhow. We should have built this one with the trimmer really to try and tame it a little. But it was built as-was so we left it out (it was optional on the Doug Hammond's original schematic).
The fat switch you'd normally use to fatten single coils. With the Feline in the demo it's a bit overkill as it's already really thick sounding. This is in fact this pedal pre-rebuild.
I'm always so jealous of the artwork you come up with.
Looks great!
How many of these have you built now?
I sometimes wonder what pedal would merit Gattsu, of Berserk, to get front and center.
Guts is HARDCORE.

Sholicons or pedals? Probably about 4 Sholicons (+ 2 plain Hot Silicons) and, errp, around 200 pedals...

mhm :)
nice hollow ichigo
Hey Juan, very nice build! I am going to have to try doing something like that with the SHO.
Quick question... I have 2 chilicon's, one from the old etched PCB from Barry, and the other is Rev 2 from his new Fab boards...
I noticed on the newer version, they have on Gain lug 2 an Electrolytic cap as 47µF going to ground
and on the old version there is a 4.7µF cap there...
From my comparisons, the old one with the 4.7µF seems to be a brighter pedal and not as muffled... in your face even
Which cap do you have going there? I have to tinker some more because it could be the transistors too...
My old pedal has mixed transistors* BC109 and other types in there that I forget... and the newer one has the quad of 2N5089's.
Anyway... NICE BUILD DUDE!!!
;)
It's built it on the original schematic (but with different transistors):

yeah, that is the exact same schematic my first build used...
I think the other one has a typo on the layout and the cap should be 4.7µF like on the schematic, and not 47µF
I am going to replace that cap and see if the pedal gets brighter... lol ::)
