Speedy Saarinen is a professional guitarist with a strong career which has lasted already for three decades : In addition to being a professional musician, he's also a teacher, a producer, mixing engineer and an entrepreneur. He brought us his collection of pedals and a looper he'd been using for a while. Our job was attach everything to a new board. We also installed a new power supply to get rid of all the old separate wall warts. This was also the first time we had the chance to try out the new, ultra-compact Squareplug SP550-S stereo plugs for custom Y-cables.They were a perfect fit for the Musicom Lab EFX-LE looper.
