Yeah, it can get a bit dirty with a strong signal. That's part of what I meant when saying its not totally transparent. It adds a bit of colour (or is that juice?) to the signal. I don't have any high output pickups though, so it works great right at the front of the chain after the buffer. Although if I had a boost/buffer like you it might not be as happy with the boosted output.

The more transparent Ross-style have their place too, so I am super interested to see how a stripboard build of one goes.
