This coming saturday (1.oct) there will be a soldering course at OnkartGromt’s office in Søgne. You will be able to solder your own Grombass or OpenEffectsBox.
This will probably not be the last event like this, so just send a mail or facebook message if this is something you want to join at a later stage.
Here is a brilliant e-book on basic soldering. This is a free book that you should share with your friends and spread the knowledge.
