Hi Robert,

The pedal sounds fantastic. Very organic and warm. I wonder though, if a vertically mounted tube is a practical invention. Considering pedalboard cases and bags (I use a small Gator board with bag), makes it difficult for me to find the pedal practical. Demounting the tube....nay....
I have once had the chance to play a Tube Driver, which also has a tube insinde. Of course the footprint is slightly different, but the pedal fits better I think.
All in all the R1 contributes in a very good way to your setup!
