I have a FI. I HATE messing with software and all that malarky. But that is OK cos there are people who do love that stuff and they put the presets up for easy download. Happy days.
A rewind would probably not break the bank if you are already looking at the outlay of another pickup. And you know you would not need to accommodate a different pickup.
Mic Preamp with more options than I will ever use. Different capacitors and discrete amplifiers and output transformers for THE TONE. NIce saturation knob for THE TONE!!!!! More gain than I know what to do with for the WEEDY microphone.
