I like the Zendrive 2 so much that I sold off some pedals and got a Nu-Valve looking for more of that Tube magic from Hermida. At first I thought it sounded like the Zen2 with the EQ knobs calibrated different but I'm finding it to be different. It does have the same positive qualities of the Zendrive2, that being it cuts a mix, it's touch sensitive, all while having that tube tone that just kills at band level volume. The difference is exactly what is described about it. It is more British in flavor in that it is not as smooth and smokey like the Zen. The attack is a little more aggressive. The bottom is different also, not quite as round(?) as the Zen. I'm able to actually get just about all my sound from these 2 pedals(with stacking). I have a timmy that gets into the mix from time to time but the warmth of these tubed based pedals usually wins out. The gain level on it is about the same as the Zen2 but the more aggressive tone gives it a "higher gain" feel. Both pedals have a certain tube saturation going on that even with a low-medium gain structure they are comfortable to play leads etc. with more ease. In other words, what would take more gain on an another pedal to feel comfortable to play a lead, seems to work at lower gain levels on these pedals b/c of that tube saturation thing. TGP is the blame for me reaching this place. $500 for two pedals. But, I don't regret it, they're worth it. If Alf ever releases that Blackface pedal....I'm gonna take the plunge for sure.
