Hi
Had enquiry off a member on Charlie Halls site about my settings for Katana 100 head Mark 2 and should you want to try them you are welcome to download them here with link below.
I am not sure how this will work on the 50 watt version as no presence control ? And other features that 100 watt version has and it was written as stated for 100 watt Mark 2 head.
Please note this includes flavours of AC15 and AC30 tones which should be evident in the editor. There are some eq and compression settings which you might want to adjust to taste in each amp setting. Good luck.
