  1. They are in phase so I basically just confirmed the combination wasn't fluke. Had that idea for a while but with crossovers to filter a bit of everything out of everywhere so you end up tailoring the sound a bit more
  2. I would still run Animated/Voskhod parallel with an LS-2, but very, very, very well! I mean, yeah, it's pretty good with guitar too.
  3. God damn it James, you're always first. Something something Voskhod on pre-order etc etc.
  4. Hahahaha, I knew when watching it back I would get a comment about it. I genuinely struggle with my pinky for the past decade, Im in the practice of taping my middle two fingers together and doing the 1-2-4 method because of it. I might drop the price in a few days to compete with a competitor and clear out old stock for newer builds. And Voskhod.
  5. So I went silly and shrunk it down some more. Album: https://imgur.com/a/i0Zfg Even managed to record with it today. https://www.youtube.com/watch?v=b6Gq3DaSEDs Interesting point I should mention, on the newer ones, I put the extra filtering caps like the original, plus a 100 ohm resistor between power and the board, it's a lot quieter when you mute your instrument and seemed to get rid of a high pitch whine, whew.
  6. I still follow you (well, your old band), oh man, I was so keen to hear it. I fucking love it <3
  7. I actually had to remember what it did because its been so long since I have ever thought about the switch. What happens is that when the switch is flicked, lets say off to on, you introduce a resistor to go to ground. These two resistors sit on the base and the emitter of the transistor pair. Now, both the base and emitter *already* have a resistor going to ground so what we essentially do is put resistors in parallel. So 100k || 100k = 50k ~= 51k in real world parts And 4.7k || 4.7k = 2k35 ~= 2k2 "" "" That doesn't mean too much but all it does is change whether more voltage goes to ground at the base or more goes at the emitter. The 100k to 50k changes the transistor bias, the 4.7k to 2.2k changes the gain. It's odd though that the values picked don't give it a substantial difference but that may explain why it's possible that harmonic content may be slightly different as a result of the switch but that's reaching pedantic levels that a lot of original owners argued made no audible difference, hence it's exclusion. And weirdly enough, you actually made me realise that in the last public schematic revision I may have labelled the switch wrong in the schematic as DPDT when it was SPDT meaning it was not both being switched on, but one or the other. Was that long ago, the difference either way is really minimal but I will definitely check. I basically just compensated for the switch by choosing one side with the closest part replacement 51k, hence choosing one side of the switch to represent and picking the closest parallel part to minimise part count. It's a few dollars saved each build. So tl;dr, the switch either turns down the gain, or the voltage bias but in a way that equates to same level and frequency filtering.
  8. Im not sure what it identified as but it does sweet FA. Now thinking about it, it did change the filtering but would have made more sense if the resistor and capacitor were adjusted to select a different frequency rather than the same just with different values. That translation. Eeek.
  9. Meh, it's not really anything fantastic or groundbreaking from a schematic point of view, just really, really well thought out filters that give it a unique tone. I'm more in it for the EQ and the balanced output. Even then, there isn't anything overly surprising, the most surprising is actually how the switching is done using CMOS and FET's. For a summary (at least of the B3K) since I'm not going to write up the schematic for this: Bypass with FET's and CMOS Blend using unity gain opamps JFET's configured like a Mu-Amp Filtering (some HPF and LPF) and notch filter at 350ish Hz More filtering, switch to change attack Opamp gain with drive control Switch for high pass filter CMOS overdrive (honestly this alone sounds fantastic just on a breadboard and it's 70's era stuff) A fuckton of opamp filter sections to reduce some more mids and overall shape (I'm guessing insert EQ stage for BxK/Ultra etc) Return to blend This is basically how a good bass overdrive should sound. It's similar to how the animato works out really well with blend. I prefer this as more of a pushing past clean rather than a full on distortion. Honestly the biggest thing I could think that would be a great improvement is to control the depth of that notch. It's so characteristic yet it can make things sound a bit empty, especially if you want to not use it for metal sounds. I can, 100% understand why this pedal ends up in studios with its frequency profiling, I even used one myself for our whole EP. The switches are damn cool though, I will give full kudos for build quality and the thought going into it. As a friendly reminder, this is what I'm doing, so cool your jets, I just enjoy being curious about this all.
  10. I was going through the list of components it could be and I found nothing would match it up unless it was a PNP, which is against what my little ESR reader suggests. I'll have to breadboard it all properly when I get a chance. I made a little fix as well which I have to update here, forgot the second half of the DPDT switch, for the LED. On another forum, they mentioned the little bit of bleed with the bypass can be eliminated by using a 3PDT to short R9 for unity gain on the IC, which may even be a LM308. Might need to dig some old electrical notes out to measure the slew rate of the IC.
  11. Ehh, here's the schem then if you aren't registered. Completely agree Jaicen. I also think that if the transistor was lower gain, it'd actually help. Turning down the volume on both my bass and guitar made it sound tons better.
  12. And the mt'Lab FAT Humster is reversed. *sighs* It's still shit. http://www.diystompboxes.com/smfforum/index.php?topic=118679.msg1105506#msg1105506
