Carlin manufactured pedals in Sweden during the 1970s and several artists use his circuits to create their sound. The best known are the Carlin Phaser and Compressor. Moody Sounds offers these pedals as a kit. Nils Olof Carlin was there to get the clones just right. The circuits hold up well despite being 40 years old, but we made some adjustments considering what has often become standard in the pedal world: the clones are 9V powered, input jacks are on the right side, and they have true bypass.
