Fuchs Pure Gain boost?

[hubble]

anyone every seen/heard one of these?  no schems around to my knowledge but id love to see one

their website hypes it up a little "A unique circuit topology unlike anything currently on the market"
they sound pretty awesome, i wonder how unique they really are though

The Pure Gain Plus, combines two of the world's quietest gain boosts with an A/B box. Based on an ingenious suggestion by Dweezil Zappa, the Pure Gain Plus allows you to both balance and boost the levels of two guitars (for example a single coil and a humbucker guitar). It switches to mono operation when only one instrument is plugged-in, allowing it to function as a three mode booster: bypass, and two discrete boost levels.
 
Like the Pure Gain, when the boost level is at '0' position, the booster acts as a buffer, reducing your guitar's impedance to about 20-K, allowing it to drive long cables or additional effects on a pedalboard with minimum sonic impact. Until you've heard the increase in clarity, detail and reduction in noise this impedance change can bring, you haven't heard what you've been missing!
  This describes a stage tool, apparently set to help reduce Dweezil's [or Fuch's owner] with the stage Tweekin' duties. Looks like a handy pedal for Dw to introduce his guitar outputs to...I bet it works great for him, it helps to switch guitars I think, getting both optimized...can be tricky...I have a set of knob tweeks I do...
9-V battery or DC adaptor powered, the Pure Gain Plus features bright LEDs for each input as well as showing which boost channel is engaged. When the unit is bypassed, the respective LED blinks, and when active it turns solid. Like all Fuchs pedals, the Pure Gain Plus features solid cast aluminum power coated enclosure, heat cured silk screening, dual-sided heavy circuit boards, premium switches and controls, and premium electronic parts throughout.
  I read this as a good description of the function, performance and features of the Fuchs -the BOM and schematic of the boost stages.
  This section in particular is interesting to me:
  Like the Pure Gain, when the boost level is at '0' position, the booster acts as a buffer, reducing your guitar's impedance to about 20-K, allowing it to drive long cables or additional effects on a pedalboard with minimum sonic impact.
  Might sound good even driving a FF [for those with FF...then a click off of FF has cable driveability in the default signal].
  I've never seen anything exactly like it.

i wonder how unique they really are though

hmm, i thinks similar "unique" as the plush-drive... ?
