Great pickup sound

I was just browsing a little on youtube and found this clip with Darol Anger and The Furies. Darol is playing a London five-string fiddle from G. Edward Lutherie, and I must say I find the apparent tone of the pickup really good, very clean and effortless.
I do not know which other gear is used but it looks like it is only the built in pickup through a preamp.
I will have try and get a chance test these instruments from G. Edward Lutherie.
