A Phaser to me is an acquired taste and I like it. I was using an original 70s Electro Harmonix Small Stone for years and sadly it was only the rust on the casing keeping it together and had come to the end of it's gigging days, one more stomp wold have been it's last. So I was looking for a replacement.
The old EH only had one knob so it was either on or off so a mix level is a nice addition. Therefore subtle is the key for this pedal. It can make a creamy rich swirl thickening up a nice clean or distorted sound without being too in your face. As I say subtle as it can also produce vomit inducing sonic wobble if too much.
When the Helix is switched to the 'Smooth' setting it really makes a good if not better replication of my old Small Stone, unlike the EH it is built like a brick so it should last well. It has a very clean sound and little to no background noise.
The tone print is a nice feature, but as I have found with other TC pedals, I very rarely need something which is outside of the standard available settings and this is no exception, if you need sounds outside of the standard on this pedal then you must be playing really 'experimental' music.
All in all a very nice pedal, does the 'phaser thing' very well, so very happy with the purchase. Highly recommended.
