Question Is it possible to get the Helix Phaser to sound like a Phase 90 Answer You can easily get the this sound by using our TonePrint Editor the Vintage template on the Helix. What characterizes the Phase 90 is that it is a 4 stage phaser. To get a similar tone set Mix to 100 % (full right), Feedback and Depth to around 3 o'clock. The Modulation speed is setup to go a bit further compared to the MXR Phase 90 (range of the phase 90 is approximately from 7 to 4 o'clock), but it is nice to be able to set slower times as well.
