I was so thrilled to see the Arbitrator fuzz appear in the new group of pedals from the recent update, and so disappointed in the result!!! It sounds HORRIBLE!!!!!! The Fuzzface is one of the most inconsistent devices ever made due to the ever drifting Germanium transistors. They were phased out of audio electronics decades ago due to their instability. In laments terms, they drift at an incredible rate. The most noticeable symptom of a Fuzzface that has seen better days is when it begins gating. At that point you can try swaping positions of the 2 transistors in the unit. If that doesn't help, you either have to replace the transistors, or the pedal altogether. So, if your going to take the time to add a Fuzzface to the Helix, FOR GOD'S SAKE FIND A GOOD ONE TO CLONE!!!!!!! The "Arbitrator Fuzz" is a perfect example of the worst sounding fuzz face you can find. It gates HORRIFICALLY!!! No matter how you adjust the two parameters, the effect gates making it completely USELESS!!!! Please find a good unit to clone and replace the current one, as it is a waste of space in the Helix!!
