I was skeptical after having gone in and out of modular over the past 7 years. At the last minute I changed my initial order of a loaded Syn2 to a Syn1 with a SLO mod. Wish I hadn't. IMHO This new gear is a game changer. The SLO is chewy, 3D sounding, has sizzle and a nice bottom end and doesn't sound the least bit sterile or small when A/B into the loop of my JVM. It sounds like another channel of my amp and that is exactly what I was looking for.
