I'm planning to build one and wonder how similar it sounds. I know there is nothing magic about it as it is <just a buffer > with some nice exciter tone shaping filters. The original sounds so good in my opinion.
Anyone compared it to the real deal?
The threads here about this particular pedal tend to go south quickly... there are possibly some build reports that might give you the insight you're looking for.
There was a thread on Reddit with some comparison scope images but it appears to have been removed. (that fact alone might answer your question)
