Does changing modes reset the controls positions on Spatialist? In other words, if I have the control 1, 2, & 3 where I like them and then switch modes, then switch back, do the values get reset where I’ll need to move them around to the settings back? … What if I unplug power and plug it back...

What would happen if I used a B25K potentiometer in a Sproing Reverb instead of the suggested A10k potentiometer?

I’m wondering what a good “first pedal” or “desert island pedal” for a bass player pedal would be. I’m building a pedal for a friend who plays bass and doesn’t have any pedals yet. I know bass players love the MXR Phase 90. I also know they love fuzz, and overdrive (like maybe a Kliche with the...

Hi. I’ve been trying to figure out how I can use the Arachnid to make a single-patch FV-1 without loading in all of the diodes. Instead of the rotating 8-mode switcher, I hard wired what I believed to be patch zero in the EEPROM bank. I’m new to this so what am I missing? The schematic shows...

I wired this up and later realized I wired the in and out grounds to the wrong jacks. The ground wire for the input jack is wired to the ground lug on the output jack and vice versa. (In other words the grounds are swapped.) Is it worth the effort for me to rewire those grounds or does it even...

When working with a perf board where the pads are isolated like this (see attached image), is it best to bridge the solder between connecting pads or is it better to bend the leads over and use that wire to make the connection?

I need a simple and clear one knob boost for a mandolin. I have a stash of TL071 op amps and wondering if you have a PCB that uses that component in a simple, one-knob boost.

I just built a rat on perf board, but when I test it, I get no sound until I pull the power plug out of the unit. When I pull the power cable out of the pedal, I hear the pedal working beautifully for a second or two. What is a common cause of this?

Having trouble reading this schematic. What is going on with pin 5 here? (Muroidea circuit) Is it going nowhere?

I’m thinking about building a reverb pedal for vocals. (FV1) This means I would be working with XLR instead of 1/4” mono guitar jacks. What are some things I need to consider when designing a circuit with XLR jacks? For example, I imagine I will need to keep power negative and earth separated...

Today I bought the Spatialist. I will only need to use the shimmer mode patch. How could I modify it to not use the rotary switch but just hard wire it to always be in shimmer mode?

Where can I get a soldering sponge that doesn’t have a donut hole in the middle of it?

This is a question for those of you who sell pedals. I’m wondering if people are typically willing to pay more for pedals that have effects created by the FV-1 chip. Those chips are pricey, and I’m wondering if there is a good chance of recouping the extra cost or if people just expect them to...

Are these the same. The price is different but they look the same. I don’t mind the extra cost if it is a higher quality switch. https://www.taydaelectronics.com/3pdt-stomp-foot-pedal-switch.html vs...

What ballpark should I aim for with the 2N2222A in the Dragon’s Breath. I have quite a range of options. Is lower or higher better (for that circuit)?

What would happen if I changed the 100k pot to a 25k pot for the output volume control? (On the Muroidea)

I treated myself to purchasing one of these desoldering pumps on Amazon. Has anyone else tried these? I think it’s terrible. Wondering if I’m missing something. The tips aren’t pointed enough to get into small areas so it is hard to aim and not burn stuff. It also takes too long to melt the...

I’ve noticed that sometimes the solder pools on both sides of the PCB and sometimes it does not. Is it ok if the solder pools on the side you are working with but does not flow all the way through to pool around the pad on the other side? See attachment for example.

Am I supposed to add a component here?

Trying to breadboard a delay circuit for the first time. This 33R resistor keeps going up in smoke. I don’t expect anyone to deconstruct this whole breadboard, but am wondering common causes that I could double-check.
