I have never seen one in person though I can not see how any pedal is worth that kind of money!
Especially when I crank up my Swart Pro up to 8 or 9 and play any of my guitars through it and it is just heaven!
Of course at lower volumes that is where the pedals come in.
I just got a screaming deal on a used Xotic AC Comp and having had one of the early yellow ones I thought I would give it a shot. It sounds really great as a true booster considering what I payed, but it seems to lose bottom end at volume like it needs more Volts to push fullness and string separation. It is not an RRB!
I'm still hoping for a RRB with the SBEQ Treble and Bass controls with switchable buffer.
