Just for fun – Jazzmaster pickups

20140809_141438351_iOSYou might remember I tried my hands at pickup winding a while ago (was it more than a year ago already?) creating a set of pickups for my Jazzmaster. Or maybe I never posted that, but anyway.

With some major help from my friends I finally got around to do a proper pickup comparison! And here’s the result:

The setup:
  • Three different Jazzmasters20150524_121010489_iOS
    • (J) A japanese Fender Jazzmaster (CIJ) with stock japanese pickups.
    • (S) My own japanese Fender Jazzmaster (CIJ) with custom pickups as mentioned above (see lovely picture, it’s the left one).
    • (A) A modern AVRI Fender Jazzmaster with stock pickups.
  • No effects, guitar straight to amp (happened to be the one I most recently built, which, in my subjective opinion, sounds just great). The amp is connected to a 1×12 open-back cabinet with a G12H element.
  • A Soundelux U195 microphone straight to a CI2 Steinberg interface for recording.
The result:

Note: No post-processing effects were used, to retain the actual sound as much as possible, but all samples have been trimmed down and given a light touch-up to attenuate excessive fret noise spikes (equally for all samples).

Neck pickups only:




Middle position/both pickups at the same time:




Bridge pickups only:




  • All guitar playing by Ronny Yttrehus of Captain Gone.
  • Recording engineer: Jon Bjørnstad, also of Captain Gone.
  • Minor editing and post processing by myself.

Tap-tempo v3

I’ve been working on (still am to be honest) a new version of the tap-tempo LFO. There’s a few new features, like:

  • Rotary encoder input toggling between and selecting multiplier, waveform and tempo adjustments.
  • The just mentioned speed adjustment – You can now micro-adjust a given tempo rather than having to tap in a new one.
  • New “random” waveform – I hope to get some fun out of this one myself.
  • Many new multipliers (Base tempo is 4/4):
    • Whole notes
    • Dotted half notes (new)
    • Half notes
    • Dotted quarter notes (new)
    • Quarter notes (1:1)
    • Dotted eighth notes (new)
    • Eighth notes
    • Dotted sixteenth notes (new)
    • Triplet notes (new)
    • Sixteenth notes
  • LED indicators for both base tempo and actual tempo (current multiplier).

Source code is now available for free on github under GPLv3.

It’s not done yet, but getting there. I plan on also bringing the attiny85 up to the same standard (minus a few features). As earlier, I’ll also try to keep a few pre-programmed chips available for those who prefer not to get into the programming side of things.

Keep watching this space for more info soon.

StripboardCAD version 1.2

stripboardcad_app_iconThe second update to StripboardCAD is finished and awaiting publishing on the App Store.

This update s focused on improving the parts list and how you interact with it. There’s lots of small improvements and a few large ones as well.

Head over to the changelog page for the Download_on_the_App_Store_Badge_US-UK_135x40details.

Status update

You haven’t heard much from me lately, and I’ve been busy with a disproportionate amount of real-life stuff, but there are things to come yet.

I started working for a new company a few months ago. While this leaves me with less free time I can use for electronics and noodling, I’m fortunate enough to now be working professionally with things related to electronics, circuits, audio signal processing and microphones! I’m hoping this will have a positive effect on my DIY tinkering as well smile emoticon

I’m actively working on the next update for my pet project, the StripboardCAD app. This time around I aim to improve workflow related to the parts list, entering of data/values etc., fueled by myself starting to use the tool actively and noticing a few short comings.

A few of my good musician friends have been trying out the “Workhorse” project I put together, and they’re so enthused about it that I’ve now built a few units for sale. That was a pain in the *behind*, and took much more time than I would have wanted, but hopefully it’ll come out well in the end. I even hear some plans about a demo video; a first for anything I’ve been involved with, and only (potentially) happening because I’m not doing it wink emoticon More to come on this soon (I hope).

I’m also revisiting the tap-tempo LFO stuff. While it has resulted in some very cool effects (I’m most happy with the tremolo), it has also disappointed on a few occasions (the phaser, to name one) due to overly noisy design etc. There’s two things to take away from this:
1) I need to learn more about proper grounding in digital effects, and how to lay stuff out on a vero/circuit board.
2) There are still things I would like the chip to do, like integrating a manual tempo adjust pot, a random wave form, and more options in the multiplier department (triplets etc).

And, of course, there are a number of other ideas I’m also playing with, that might result in something further down the road. We’ll see.

I’ll try my best to post more news before the year is over, but just in case:

Merry christmas and a happy new year! Thanks for your support in 2015!

StripboardCAD version 1.1 on it’s way

stripboardcad_app_iconI’ve just about finished the first major update to StripboardCAD. What remains now is a bit of testing, and the App Store submission process.

This update is all about fixing an annoying issue with some layouts missing some of the parts list; an issue I discovered right after the initial release. Along with the bug fix I’ve rewritten most of the layout generation engine, adding some more options and general tweaking.

As a bonus I’ve added a few requested features that were easy to implement, amongst them the ability to create layouts with the component values printed directly on (rather than the label).

Full change log when everything goes live. And I welcome feedback, of course 🙂Download_on_the_App_Store_Badge_US-UK_135x40

Update (15.08.2015): The update is now making it’s way to the App Store, hopefully soon 🙂

I’ve added a change log page for keeping track of what’s being added as time goes by. Also, do let me know if you have issues, requests of ideas of improvement 🙂

iPad app – StripboardCAD

stripboardcad_app_iconRelease for version 1 of my new stripboard/veroboard layout app for the iPad is quickly approaching, and I’ve begun setting up support and info pages. There will be more to come, hopefully very soon 🙂

Update (09.05.2015): App has been approved and will be available in the app store starting today! 🙂

Quick update on app progress

As quite a few of you know I spent most of my time last year working on a vero layout app for iPad. I was initially hoping to finish it up by Christmas, but  obviously I missed that mark. That’s the bad news.

The good news is I’m still working diligently getting it done (I guess that might actually be bad news for those of you hoping I’d have more layouts ready instead). I’ve got the famous 90% ready, and only missing the last 10% that always end up taking the most time.

Here’s a few screenshots so you can get an idea where I’m at right now.


As you can see I did a quick mock-up of the Korg SDD-3000 layout, and it looks quite nice. But you’ll also notice there are a few things missing still.

All the basic graphics work is done, with only minor tweaks remaining. It’s vector based, scrolls and zooms nicely, and looks great when exported to PDF. There’s the component picker on the left and the parts list on the right, and you basically just tap, draw and move stuff around as you wish.

There’s a basic menu for entering meta data, like layout title, author etc. and this info will of course end up on the exported layout along with the layout image and parts list.

As my goal for version 1 is to be able to replicate my own layouts the way I have them drawn now, I’ve left out things like pots, switches and wire. That’s not to say they won’t be included, but not in version 1 (or I’ll never finish this thing). What I’m going to have instead is an “off-board” menu where textual representation of these things can be entered (like my layouts today).

The export menu is also under construction still. I’m hoping to be able to generate both PDFs and PNGs, but may cut it short with just PDF to get started.

Also, not visible here, is a file manager back-end that needs to be in place before release. I have something very basic right now that needs to be replaced with something proper. iCloud-support may or may not make it for this version, but I’m sure to add it eventually since it’s a feature I want to use myself.

Plans now are to complete the missing parts and try to get this thing up on the App Store somehow. I think there’s a beta-program as well, but again, that’s another few developer documents/books I need to consume to have it all figured out. We’ll see, but in the event I’ll have a beta run I’ll be happy with all the help I can get.

And so I have a somewhat awkward question for all of you. Assuming I’ll get this thing out the door, I need to put a price tag on it. I’m not totally comfortable charging money for the things I provide here (I like giving stuff away), but then again I can certainly also use what funding I would get and put it back into future development and other related projects. I have probably spent several hundred hours on this so far (most of it being a lot of fun) and would of course like to see other people getting some use from this, but in the end I did build it for myself first and foremost. What do you people think? What would you be realistically willing to spend on an app like this? From asking around amongst friend I get everything from $1 to $100.

Anyway. Hope you all have a great 2015!
