Mu-Tron Bi-Phase II is here!

We want to thank you all for following us on this journey. It seems like the Bi-Phase has been a work in progress forever. This pedal is iconic and was used on many records by numerous artists. After 3 years of development, 5 prototypes, and much grief, we can say it has been the most difficult project we have undertaken. It is a sonic reincarnation of the original 1970’s BiPhase circuit in a 1/4 of the footprint. We did our best to do as Mike says “Make it as good as if not better (than the original)”. The new Bi-Phase II has our new opto mod technology which we developed for the Microtron IV and other optical products, these allow tighter tolerance control and consistency between units. These will be swappable in the future as we come out with different mods. Other features that the Bi-Phase II has is that it routes right to left, has a symmetrical layout, and accepts between 9 and 12 volt DC. It has been quite a task for us to get the Bi-Phase II to where it is and we are beyond excited to release the pedal to all of you. These units will be for sale on October 1st at 11am PST. This will be a limited release in the vintage silver color, but there is another batch coming up right behind it. We really appreciate all of your support and patience with us as we have made this dream a reality. In the meantime please visit our store where you can read the product page for the Bi-Phase II. The warehouse has been cleaned out in preparation for the Bi-Phases arrival so the store has never been as full.
