I don’t know about the fw, but BladeEdit 3.50 is available on the Facebook group here: https://www.facebook.com/groups/185869609147018/
Hope that helps.
Interesting because I don’t recall seeing one when I changed a preamp tube in mine. But I wasn’t looking for a dsp chip either. I would be curious to know what chip he used. Maybe one day, I’ll be curious enough to have a peek.
Thanks, I was just curious since he stopped posting here around 2020 and he hasn’t updated his website in a while. I always have had good dealings with him too.
