NostalgiTone Ascension Boost Single – inverted or regular phase?

[Jeff24]

Is the Ascension Boost Single PCB inverted phase? It’s not noted as inverted.

I’m also seeing that none of the NT boost singles are inverted, even the Naga, which is based-on the Rangemaster (yet the PURP, also based-on the Rangemaster, is inverted).

All single transistor circuits are going to invert the phase. Though it only matters in a parallel or stereo rig.

I have not been marking circuits as inverting or non-inverting for a very long time so just because it is not marked doesn’t mean anything. Nobody ever seemed that interested. If a circuit is actually marked one way or the other in the shop then it is correct.

The NostalgiTone Ascension Boost uses a single transistor stage so it does invert the phase. Alternatively, the NostalgiTone Preamp Boost uses a non-inverting opamp so it does not. Also a reason to provide more than one type of Boost.

Thank you. Very helpful.
