I had a Seymour Duncan Pickup Booster pedal for a while. It was great at what it did, but I sold it on when I got a Fulltone Fat Boost and ZVex Super Duper instead :)
I also tried a Tweak Fuzz last June, and it was a good pedal. It was the best sounding pedal in it's price range, but I preferred the sound of the Emma ReezaFRATzitz (and it was only a little more expensive), so I bought 1 of those instead :)
I know this isn't the most useful post in the world, but thought I'd post it anyway :)
