SSS002 build happiness

[Bombacaototal]

Hi all, I think I spotted another mistake, this time from the Jap schematic which has been replicated to the final project. On the low filter there is no 0.01uF. The first position is 5100pF, then 2400pF, then 0.001uF (orange drop), then 1000pF (mica). I think the Jap guy miswrote it. This is in line with the other SSS amps, and it would make sense as far as the position in which the orange drop is as far as the filter.

Because 0.001uF is orange drop and 1000pF is mica they will be sonically very different regardless of the value being similar....

You can also see the size of the orange drop on the gut shot attached

Rafael, I dont think so, take a look at youtube Dumbleland vid were they go through the filter settings, very similar behavior to what it is now.

Makes sense to me. The sonic difference is interesting and I know you did your own tests using your ears and found them strikingly different. I'll open mine up again and test it out!

Looking at the size of the orange drop cap, i think it is indeed 1000pf. But this does not mean an error in the Japanse schematic. It only means that the assumption that the 10nF is the orange drop was wrong. If the 1000pf cap is an orange drop, the 10nF is a mica cap.

I just checked my recordings and I only properly captured the after properly and I must not have selected the proper input device for before I was too excited. I'll still post the video for tests

Looking forward to the video's regardless.

For another point of reference, the Ceriatone/sterling sig tops out at 5400pf. I guess it's not too crazy of an idea the 1000mica/1000 6ps?

Where is our friends who actually was in #002? We must be close...

I don't know the complete ceriatone schematic, but the input network to the filterswitches could be different.
It is strange that Nik claims he had acces to a real SSS but still wired the filterswitches in reverse on his own amp. So i don't consider his amps to be correct, but more like his own (or someone he borrowed it from) take on the sss.

I use my amp frequently with my band and it sounds like nothing else, realy realy awesome sound! Although the filter input caps might be in series, i don't realy want to change anything at this point. I did make a 'mistake' though on the highfilter. I read the values of the japanese schematic and by mistake read 2700 instead of 2400pf. The 4 looked like a 7 to me. Only later i discovered it should be 2400pf. A lucky mistake because the 2700pf cap i use the most on my overdrive sounds.

Ceriatone is based on #004 (although there are differences). But, it has the same filter network. This network only changed from #005 onwards. Dumble used both directions in his filter wiring...

Ok, so the Ceriatone uses the same 0.01 \ 0.001 input caps to the switches. I thought i did see a 22nF on the gutshot pictures, and could not find the 0.001 high filter input capacitor, but i guess maybe not everything is visible on the gutshots.

#004 has .01uF coupling cap. The 0.001uF is removed and jumpered with a barewire, but its the same topology. And yes both are visible on the gut shot

Seems like there was a lot of experimentation going on with the filters.

Do any of you use the treble switch position with the isolated 3n (2n in C-tone layout above)? If so, for what purpose?

Never. Only use case I can think of is for laying a isolated reverb track in the studio?

Feeling good about this! (Yes, my cut is reverse)

To me this would be a significant difference. I think using the higher value cap settings on the 004 without the 0.001 series cap would result in a more mid heavy sound on those settings.

No i don't use it and i also don't use the mid switch (0.001 bypass cap on the level pot) which to me is even more unusable.

The 3nF could be some dark jazz tone setting, instead of turing the tonepot on the guitar down. But that's stretching it.

Using both the 3nf and the 0.001 bypass cap does give a very heavy midhump sound
