The Carlin pedals were manufactured in Sweden in the 1970’s and many artists used Carlin’s circuits to find their sound. Most known must be the Carlin Phaser and Compressor. Moody Sounds offer these pedal as DIY kits. Nils Olof Carlin took part to get the clones just right. The circuits stand up well today even they are 40 years old. We did some adjustments considering what has become standard in the pedal world in many cases: the clones are powered with 9V DC, the input jack is on the right side and they have true bypass.
