    Does anyone LIKE soldering SMDs?

    Heh, that's the first time I've seen a set of those boards in that color! ;)

    Does anyone LIKE soldering SMDs?

    I greatly prefer hand soldering SO-8 opamps and 1206 resistors to their through hole counterparts, which at age 71 still don't require a magnifier in my case. I rarely use external flux, but .015 solder like what I think @Robert posted or .020 are definitely key. I've only done a few JFETs and...

    Passinwind Open Source Hybrid Filter Preamp Builds

    6dB is an excellent place to start for fretless, IME. I recently did a dedicated resonant LPF just for the bridge pickup on my Marco Bass: The neck gets a Baxandall Bass/Mids EQ board and then there's active mixing with two detented volume pots with unity gain at the detent and individual...

    Anyone using Circuitlab?

    LTspice has many pots readily available as add-ons, and has for many years.

    My gf used ChatGPT to prove me I was bad at designing pedals...

    I like this version of yours by far the most, FWIW. But I don't tend to dig cartoonish graphics as much as most people here seem to. ;)

    All Time Most Bestest Favoritest Chorus You Have Owned , Played or Heard?

    I haven't tried a ton of chorus pedals, as rack units were always my thing when I was gigging on bass with effects. The old Rocktron Intellifex was by far my favorite back then, FWIW. But these days I am using pedals occasionally, just as much for the fun of building them as the actual utility...

    Building a pre-amplifier with 3 band equalizer for bass.

    Thanks for the shout out. There's an undocumented option for adding a "normal" treble band to the Bass/Mids board in the open source pedal design via a small daughtercard. I've done quite a few onboard preamps that way, but I also have an all in one three band job that looks like so: I'm...

    Bass Klon

    Cool. I still haven't gotten around to doing my first one, which will probably be the stock guitar config since that might work better for a more immediate use case. I "won" the board in an @fig giveaway a couple of years ago, but somehow doing my own designs always seems to come first.

    Tayda order - EU Customs process

    I'm only an hour east of PDX but it still feels like the boonies sometimes when it comes to stuff like this. FedEx has always been great for us, but my wife worked there for many years and I did a few holiday stints and a year and a half as a full time courier, so we might be have been getting...

    Tayda order - EU Customs process

    DHL is by far the worst as far as timely delivery to my location,I think they only come out here once a week. Tayda's slowest boat typically only takes a day or three longer, and if I need something in a hurry Tayda's not where I'm getting it from anyway.

    SO-8 to DIP8 Adapter Pin access points

    Those “eyelets” are through hole vias and mission critical for connecting front and back traces, they are not meant to accommodate any other function. Decoupling needs to be done right at the power pins for max effectiveness anyway, so just do that.;)

    Modding best practices.

    In the pic I posted above you can see some of the many utility daughtercards I've had made over the years. They come in very handy for components that I might want to swap out during the prototyping phase, and this is one application where OSHpark really shines on cost effectiveness. It also...

    Modding best practices.

    1: I often use Nomex sheet or fish paper to wrap the PCB, then double stick gel, foam, or velcro to secure it: Those are just temp wraps secured with 3M electrical tape, which allow me to do mods to each board without even removing them from the pedal, or replace individual modules pretty...

    4 band onboard preamp development - First Project

    I misspoke a bit last night, I've now revised the bit about the bass/treble section. It sometimes helps to have the treble section first so that it has less noise in front of it to get boosted, but as usual it comes to down to managing your trade sets. You can do noise analysis in LPspice but...

    4 band onboard preamp development - First Project

    Best practice is to include a series resistor just in front of the output cap, something in the 200R-1k ohm range is pretty standard. This stabilizes cable capacitance drive issues. You may want to go a bit higher on value on the voltage divider resistors too, I generally go with 220k for my...

    DIY Direct Box?

    For starters, work through the various options here: https://www.jensen-transformers.com/schematics/ Jensen is primarily known for very minimally colored applications, which some people might call "sterile." This is exactly what I prefer in a DI, personally. There's been a strong trend in the...

    DIY Direct Box?

    I'll have to wade through some stuff to find whatever I have, as I swapped computers recently. But it was a super simple build and I've been contemplating doing another one since I still have the buffer and a different Jensen trafo that might actually work even better. You could build your own...
