I have a FreqOut pedal as it goes!! It is great. Never selling it.
I bought this pedal on the last day of 2018. I only paid $130 for it, through Zzounds.
This was just before it took a price hike.
No regrets :-).
I kind of wish I had purchased more of them, at that price.
Way back in the 80s (?), I purchased a BOSS DF-2 Distortion Feedbacker pedal. This was before DiMarzio subsequently sued BOSS, since I guess they had already trademarked the "Super Distortion" name, forcing BOSS to change the name to Super Feedbacker and Distortion.
I was vastly disappointed with the "feedback" feature on that pedal, but I hung on to it, anyway. The distortion was decent, and I used it for many years following that. But, the feedbacker portion of it left
a lot to be desired. To me, the overtone portion of it sounded fake/contrived, and it tracked very poorly. Actually, it wouldn't track, at all, as I recall. It stayed stuck on the primary (octave) overtone.
The Freqout, on the other hand, is far more believable and musical, to my ear, and has several use-able adjustments to really fine tune what you're looking for. It also has kind of a cool aesthetic to it, as opposed to their Polara. I don't know what the hell they were thinking when they designed the artwork. Someone else mentioned this, but the labels are incredibly hard to read, on that box. It's just ugly as shit, in my opinion. Opinions vary, and you are more than welcome to yours.
This picture was taken before I bought my first board, when I was still using Grundorf rack box covers as a board, at home LOL.
