    This Week on the Breadboard: MOSFET Driver Redux

    So this is another Boneyard circuit that I plan to build, so I want to make sure I have the correct schematic. Since the v0.6 schematic was posted, a few subsequent tweaks have been made. So I *think* the latest result looks like this, which I'll label v0.7. (changes since v0.6 are shown in...

    Deadend FX Eva (Spaceman Gemini IV)

    Here's my build. This one took a while, fitting it into the enclosure took a set of careful measurements so that everything would fit (e.g., so 1/4" jacks don't collide with the PCB, transistors or caps; etc.). Fortunately those who went before me had commented on the challenges, so I went in...

    SOLVED Cadmium Fuzz

    Any luck yet? Have you checked all the parts values? The center row of caps looks fine, but the resistor colors are difficult to read - so check those as well. Any shorts to the pots underneath? Did you use pot dust covers - aka 'pot condoms'? I also can't verify the +/- voltage wires go...

    This Week on the Breadboard: The Barber Small Fry (PPCB Tater Tot)

    Thanks guys! So here's the hopefully final schematic. Let me know if anyone finds any additional changes.

    This Week on the Breadboard: The Barber Small Fry (PPCB Tater Tot)

    @Chuck D. Bones and @cooder - So is this the correct final schematic?

    Replacement button for SR&D Rockman Sustainor?

    Another possible option is 3D printing a replacement button. You could search on Thingiverse, Printables, or Thangs to see if someone has already designed a replacement. What make is the switch?

    Tayda packing and shipping

    I emailed them, and it is the painting of enclosures that is causing the delays. Tayda is clearly working very hard at addressing the situation. I've ordered TONS of stuff from them in recent years, and every order has come through in excellent shape and without error. So, although I wanted my...

    Yes i saw that his stuff is very highly desirable, you really scored on a valuable find! So you'll be doing him a service by respecting his pedals. Poor Ralf, however...

    Tayda packing and shipping

    I'm also seeing delays of almost 2 weeks in my last 2 orders, which never happened before in previous years. It seems to be recent, the last ~1-2 months, i.e., once the orange guy's tariffs really kicked in. i suspect they are having to do all sorts of supply chain gymnastics to avoid charging...

    1590A Tone Generator

    Mouser. There you can buy just 1, or for practically the same price get 10. So maybe you have a few left over, not tons.

    SPICE library

    Here is a website with a ton of SPICE & LTspice libraries that might be of use to you: https://ltwiki.org/index.php?title=Main_Page There's a ton of models there, if you look around within it.

    Ample Alpaca - less low end and less gain mod?

    Hmm, and I'll also add to my earlier comments. Also note the differences in the feedback loop for the 2nd IC stage in the schematics posted in $9 above - specifically R3 = 1Mohm for GGG, vs the equivalent R4 = 2Mohm for PedalPCB. So there are multiple sources of gain differences.

    Ample Alpaca - less low end and less gain mod?

    The GGG version has a difference from other versions - note the difference in where R2 (in GGG schematic) is placed vs the equivalent R3 (in PedalPCB schematic). This clearly leads to gain differences between the two PCBs. For the GGG schematic, w/ the Drive pot minimized, the feedback loop...
