Hi there,
I just bought myself a used Katana 100 as a first “bigger” amp, and I am really happy with it.
Small correction to the Tuscany text:
The “Effect Level” is not adding the effect to the main signal.
In fact, if both “Effect Level” and “Direct Mix” are set to 0, you don’t hear anything.
Thus: “Effect Level” changes the volume of the effect signal only,
while “Direct Mix” changes the volume of the untreated signal only.
But I think that most users will rarely use those virtual knobs, anyway…
Enjoy shredding!!
