Yes but 180° from IC1A + 180° from IC1B gets you back where you started.
Also phase is only an issue when you want to mix two signals (e.g. for a clean blend).

It's also trying to melt your speaker coil with DC.
Needs an output cap just like a '386. And a Zobel network.

Voltage Meter 1 and 2, Voltage Generator 1 and Voltage (Generator) 1 (the sequel): 9 volts. They are required to compute the transient simulation in the insert. Look for TINA-TI or SPICE in general to learn about circuit simulation.

So the switch would activate or baypass the converter, right? And feed your pedals the unregulated output? Have you thought this through? Google says About 2,920,000 results for "adjustable DC buck converter", and as far as I can tell most are adjustable. There are many many chips to choo...

Depends on what you mean by "isolated".
But if this second part is also op-amp based why not use the bipolar supply there as well? We'd be more able to help if you tell us the specifics.

Would you be willing to settle for middle+others in the Center position of the mini-toggle (instead of Down)? That would simplify it a lot: you'd only need a three-position SPDT normally-closed switch, the Les Paul type. Or any other functionally compatible type like your blade. It would be a tradit...

Yeah but you'd need to understand what those do like a nerd and then do a bunch of math *groan*. The People just want to know which ones have the most tone, goddamit! Regardless, Intripped's response is technically correct (the best kind of correct) except my minor objection. Since 25% to 50% derati...

as far as I know adding resistor like this should decrease input signal Right! Because you said if I hit strings harder it still sounds farty So the solution is to scale the signal down so it doesn't hit the https://static.wixstatic.com/media/36fc8d_306ce56411f94daa914ca620cca147c1~mv2.jpg/v1/fit/w...

Hey, welcome to the forum! The effect works with no power I'm sorry—what?! https://media.tenor.com/8yV4IOLalYoAAAAd/what-confused.gif when the pedal is off there is no clean bypass signal Are the wires soldered to the switch? From here it looks like they're just lying over the contacts and not in th...

You could still distort the second op amp if you really wanted to (max eq and high input signal).

But it was DESIGN BY USA! Or designed and built by handmade, not sure yet.

I don't see any DSP but there's plenty of op amps and passives to make a distortion.

All the commercial active pickups, onboard buffers and preamps use op amps and nobody complains. You have low power consumption ones too. Or go with R.G.'s if you want to be fancy.

How do you figure? By reading books on electronics. This circuit doesn't have the BMP-style tone control with its 10 dB insertion loss and significant voltage division with the load (the volume pot). I.e. a 100 K pot won't do shit in these very different circumstances. Germanium diodes sure don't h...

How do you figure? The difference is 0.01 dB.

No, it's not. How would it form a voltage divider if two pins are shorted (2 and 3 in this case)?

I suspect this comes down to the switch I used Why? The switches are electrically identical as far as the circuit is concerned. Can we see a schematic so we might know what you're referring to? If the switching is the same as in this pedal , note that the LED is between Q (pin 13) and 9 V, not &quo...
