The Palladium is not an actual preamp. I compared my Soldano GTO clone with a H&K Tubeman and there was no comparison, and I didn't even love the GTO. Not sure those Tubemans run at proper plate voltage. After having a GTO, it really bugged me the fact that it only had a tone control. I couldn't do anything with it besides "his thing". It sounded great with a boost but not much else for my tastes, so I eventually sold it. The SS-20 is a metal machine. It's not as tube-ish as the SS-11 since it has only one tube (thus the other 2 gain stages are JFET-based) but still sounds tits and for some stuff I prefer it. It has heaps more gain as well (I run the SS-11A dimed where the SS20 runs gain about halfway). Please tell us more about the Kartakou Beastbox. I really want to get one in next sale, but the fact that you can't tweak crunch and lead channels independently in any way but gain worries me a little.
