Poly Capo/Shift has too many artifacts an sounds bad in Helix Posted December 2, 2020 2 minutes ago, DarthHollis said: Don't assume that the Poly Capo, Digitech Drop, or any other harmonizer type effect is going to 100% replace another guitar that is tuned to what you want. No matter how good they are they are not going to be perfect. In a live situation I have used a Drop many times and forgot it was on when going to another song. You tend to not even notice you have it on. But in a recording environment there are artifacts that may be heard. For me it was much more noticeable with clean sounds and more complicated chords. Does the Poly Capo replace the Digitech Drop? For me it does. I will probably only use it once or twice in an entire night and I guarantee no-one will notice. If I was going to do more songs (like 5 or more) I would probably have another guitar tuned to D standard or whatever I need. If you want to compare poly effects to anything, the be all end all are Eventide products. They are kind of considered the best in the industry. They are still not perfect but they are amazing. I have to think the Line 6 has gotten pretty close to Eventide quality. Remember, the quality is not in the hardware but in the programming. Line 6 has created an algorithm that is supposedly faster than at tracking than any other out there. For more accurate tracking you can slow down the tracking but there is the trade off. totally true. But that is different from recording his guitar through it and, in the recorded track afterwards (without the guitar's acoustic sound in the room while he plays), he hears both the transposed tuning AND the original try guitar sound. He can't say if it works for him or not if the basic functionality works incorrectly on his helix compared to all other people's helixes.
