What i noticed was that the 0.01 and 0.001 caps in series sound smoother than in parallel, but there is less mid. It sounds good but a little bit scooped.
When i leave the caps in series but wire the 470k resistor to the junction of both caps (the other side of the 0.001 cap) the mid frequency's return while the smoothness stays. Without the 470k resistor the mid is also back, but the highs are somewhat harsh.
I also bypassed the inductor to see what the effect would be. I could not hear any difference for the bass response but when removed (shorted) the highs also get some kind of ice picky harshness. (All sound tests are with overdrive)
Looking back at the spectrum of the recorded tracks it occured to me that in the end, the guitarspeaker is what makes the filters / amp work and sound like they do. Sure the output of the filters show a much higher level of high frequency's than low frequency. This may appear unbalanced, but when it goes through the guitar speaker, this brings the balance back. This is the 2400p cap selected with overdrive engaged and the bass filter up 3 clicks:
The only thing i now wonder is if perhaps the japanese schematic has the 470k resistor drawn wrong too. Could it be attached to the input side of the 0.001 cap instead?
It would be more consistent with the way the Ceriatone SSS is wired. I mean: If the 470k was suppose to be wired to the output of the 0.001 cap, why leave it in when that cap is no longer there?
Japanese schematic: Alternative wiring of the 470k resistor: Ceriatone wiring: Do any of you have any thoughts on this?
(Or perhaps a higher resolution gutshot photo?
