OK. I need some math (and French lesson :unsure:). The total to pay is 25,50 € (about 28$). 25,50 € = 17,50 + 8. But how we can calculate these number? What's 2,92 €? PS The description (potentiometers, diodes, inductors) it's because the package it's been open up and check up? Maybe to control...

If you want to add taht one band parametric circuit you can do it, and with it you can boost and cut a certain range variable frequency. I can suggest you to change the C6 with a 4.7nF to get a basic sound with a more flat mid, then use the one band parametric eq to shape the sound, but I can't...

Well, the HM-2 with bass and high boosted has a mid scoop sound, and the FY-2, I see from the schematic, has a notch in the mid frequency. But, if that is not the thing you're searching you can fill the scoop putting between C7 100nF and the ground a 3.3k resistor, for example. Or you can...

For presence frequency I mean higher frequency, but I play guitar and I don't play around bass pedal too much, so I don't what works fine and what works bad. When you increase C5 you will cut less bass. Using a 100nF the difference in the low end should be substantial, at least around the 100Hz...

If you look at the Friendly Fire Fuzz schematic you could change C5 3.3nF cap with a bigger cap. A 100nF cap will change the bass peak from about 330Hz to about 110Hz and this gives a certain boost at that frequency, too. Then, if you need higher presence frequency you can reduce C4 from 2.2nF...

I'm from EU, too. And I'm trying to understand how much I'll pay if I place an order from Tayda, as my usual about 40-50 $ of material. I contacted Tayda, and they told me that there's new costs of the Registered Mail delivery, and now it costs even more than DHL, so they suspend it, at least...

I'm trying to understand how works the Mid Boost pot without look at the schematic. :D Edit: I was wrong, I know how that pot works! A few of days ago I was trying to add to the schematic, that actually seen because I got it from a veroboard layout, a pot to change the frequency without use a...

I didn't check my cart in Tayda since a while. I'm from Italy, and I had, the last time I checked, the Registered Mail shipping available, though the the delivery time could to be until 90 days. Yesterday I saw I can use just two DHL shipping, that means I have to pay, probably or for sure, fee...

I'd really like to know the schematic of this new PAL800.

Hello. I tried here to find some suggestion to import in Tina TI software the spice of the CD4049 to play around it with a schematic. https://forum.pedalpcb.com/threads/design-challenge-2.5847/post-82232 I downloaded this, thanks to the user fig. https://forum.pedalpcb.com/attachments/17239/ I...

Thanks for your replies, guys. I'm looking for a CD4049UBE spice to use with Tina TI to draw the schematic of the Red Llama and to see the frequency response, etc. The Red Llama schematic is very simple, and I did some experiments on breadboard, but I'd like to draw it, anyway. I don't know I...

Excuse me, I seen this schematic and I noticed something weird/knew. Those transistors mosfet type symbol with CD4007 label. I use Tina TI software to draw schematics, but I can't insert CD4007 to draw the Red Llama schematic. Is that maybe a sort of trick to "emulate" a CD4007? Edit: I'm...

A pot in front of the circuit, maybe?

I think I searched the schematic of this pedal, but I don't remember I never found it.

Thank you. I'm going to try those tricks when I'll build it.

I guess it was right, I tried even to replace it with a 47R, because some schematic has it, like the 4.7k was a mistake, but it sounds wrong or something, I don't remember. I checked it a lot of time when I built it some years ago.

Very nice! :cool: I built it on veroboard (with the external bias pot). It's fine, but my decay pot does nothing.

I'd like to build a pedal like that, but I want a gain control, too. Do it really clean up well with a volume in front of it? Or where I can place a gain control in alternative? Thanks!

I guess it will make almost no difference. I'd say if you can hear too much treble you can increase the 6.8k resistor.

Well, I think it's just a different approach to the jfet version of JCM800. Consider that the original amp schematic doesn't have R19, C13 and C14 (in pcbguitarmania. schematic) nor C13, C14 and Trim4 (in PedalPCB schematic) because in the tube version, I'm not an expert, works difference, I...
