Yup, I have the Superlead and I love it. I run it through my Randall MTS lynchbox with 6CA7's and it is awesome. It also isn't noisy to my ears but diff power supply and setup will always vary. Tons of gain on tap if you want it, I run it with preamp gain maybe at 4 or 5. Plenty for me. I compare it to the mts mr.scary module and it is more detailed and better over all. Very happy with this and good enough for me seeing as our Canadian dollar is ahit and I will never get my hands on a real slo. Another plus, great communication with them, well packed, quick shipping from Russia.
