I’m new to gretsch and filtertrons. I think filtertrons sound amazing. I like them more than my single coils right now and they have no hum. I checked out some examples of other variations of filtertrons on youtube and they all sound fantastic. In fact I preferred the filtertron gretsch with high gain (i think he said it was a powertron) more than the les paul which was surprising. They’re super versatile pickups. I’ve played guitar a long time. Why isn’t the filtertron design more popular outside of gretsch?
