The owner's manual and settings for the British (and all CS pedals) can be downloaded from http://www.tech21nyc.com/support/index.html
A quick note about the VH setting: The mid control should have been at 11:30 and not at 1:00 as suggested in the Tech 21 settings guide. I will re-record this portion of the clip and upload an update in the near future.
This is the long version of my Tech 21 SansAmp 'British' demo. It's a great pedal for stage or studio use and will cover a LOT of the classic Marshall sounds. The 'Character' knob is your key to its versatility as it is on the other pedals in the series as well. Check it out it if you want a ready-to-go truck load of Marshalls in a box.
