    Hi all, first time poster here.

    I’m planning on building a Ratt with a blendable Emerald Ring using a Buff n Blend, so the signal path would be:

    ratt -> bnb send -> ER -> bnb return

    My question is whether I would need to put in a Stage 3 in the signal path at all? I can’t seem to find wether the Ratt is inverting or non-inverting. Sorry if this has been asked in the forum and I have overlooked something during my research!



    Bas,welcome, the ratt is non inverting it’s output is in phase with it’s input

    First stage goes into the + input of IC1 the second output comes from the source of Q1 making both stages non inverting

    Here’s a link for Tonmanns Phase Determination guide on my google drive allowing you to work it out for any circuit





    Awesome! Thanks Billy, appreciate the help!
