Hey, I am building a few of these and I notice of all of the smaller ones in the pF range, why is the 15pF the only one with a tiny spot to install? And the 220pF and 470pF go in a larger spot? Are we supposed to use a larger box type/film cap there? .22n and .47n? Makes sense based on the...

Hey, I am building a few of these and I see you used the caps I think we're supposed to swap out. Notice of all of the smaller ones in the pF range, why is the 15pF the only one with a tint spot to install? And the 220pF and 470pF go in a larget spot? Are we supposed to use a larger box...

I wonder about the caps used in the Pythagoras PCB. I see the 15pF which I assume is one of those tiny Ceramic round caps. I see the 1uF calls for the coated MLCC types, but what about the 407pF and 220pF caps. The spots on the PCB are much bigger than the one for the 15pF, Are these values a...

Oh I am! I'm about to buy a pythagorum w FV1, and an arachnid or 2. Going to grab a few module 8 and builder EEPROMS for comparisons and I'll figure the cheapest way to get the few FX I need. Thanks. And... STOCK. I get it. The effect is there, but the EEPROM might be written to change what's...

Hey, is this thing on? I too use the Arachnid for like... 1, 2 or 3 effects. I just had a question answered where someone suggested I save the money on the EEPROM chips and just use the ones pre-programmed in the FV-1 chip. IS this right? I literally want to use the multi fx pcb for flanger...

Wow, thanks! I do feel the notes and descriptions of these circuits are limited on the site. This issue aside... I could be saving money on each build without the EEPROM chips? I literally use this pcb for Chrous, Flanger, Pitch shifter, all of which are apparently included in the FV-1 Spin...

I just realized that I don't need the Mix pot to be replaced by any jumpers or resistors. It seems that with only the effect circuit coming that way and past R21. Unless the circuit is happier knowing it's all connected as designed? Maybe the chip wants to get that bleed off from the MIX pot...

Resolved

I will remove the resistors in place and put the mix pot in to do just that. Of course audio probe! How dare you? Haha And... What's this about internal programs? Like there are already programed effects in the fv-1? And then the Eeprom works off of those? That's new to me, if so. Thanks!

Yes thanks! 0-8 is the same as 1-7. Easy as that.

Everything I use is from Pedal PCB. It worked until the jumper from the 8 pt rotary switch touched one of legs 1-4 of the eeprom chip. I replaced the Eeprom with another I had on hand and still the same. Best I can do for now is to replace chips one at a time.

Hey, I'm always reading back to see what's what when building this circuit... R20 was removed because it's in the circuit for the dry signal, no? Not that a 1 cent part is breaking the bank, but I am trying to understand the circuit as well as modify it for my needs... I am confused even though...

I AM making a few Stupid Sexy Flanders pedals. And of course will have sexy Ned in his Ski Suit!!!

Yes, the eeprom builder chip. Or module 8. But yeah that's the eeprom.

Oh hello, Schematic attached. I built it, it worked. But I lost track of what the 8 programed effects were for this one. So I was going point to point from the rotary switch source using a wire. Why not use a switch? I actually just want this for one or 2 effects using a toggle switch. And the...

That pretty much sums it up... I have a clock noise on my Arachnid Build. I'm not sure if it affects all of the effects as I hot wired this only for just 1 preloaded effect. What keeps the time in this unit? The VF1? The TL074? Bad crystal?...

So the chips are programmed from 0-8 but the pcb is marked 1-7. Seems silly to have to ask but What's what? Is 0 on the chip 1 on the pcb? Or is 0 actually 8? Thanks. I'm an idiot. I have so many programmed chips and forgot where I put what. To test, I jumped out all pads with 50/50 resistors...

Anybody still here? The arachnid has been great and I have a collection of module 8 and builder chips that are programmed, but I don't know which is which, I lost track. So, I have to test each board and move the jumper around the selector switch. BUT... The programs are numbered 0-7 and the...

Hello, Hi hey hello. Is this thing on? I'm back at a few Valhalla builds and a year and a half later, I understand why buffered bypass has it's place and benefits. Looking at the schematic for the build, I'm not sure I see where the buffered circuit it. The scheme doesn't seem to include the...
