Hi,
Oh it's not really an MP pedal but Mad Professor Ltd manufacturers the Simble and markets it.
It can not have a Mad Professor logo because per definition and also on FAQ all MP products are designed by yours truely
.
The BJF design was dropped on MP products because it was implicit that BJF electronics designed them.
So the Simble has its own webbsite:
http://www.simbletone.com/Personally I have declined working on things Dumble per principal and I also have nothing to do with this product.
MP Amplification has told that they no longer work with a personal cult but that they are a company.
My personal view is that the Simble relates to Mad Professor Ltd something like Alfonso Hermida relates to Lovepedal.
I did play the Simble at NAMM and thought it was a nice pedal capturing a sound many might wish to have.
