I received my Deco today about 8:15 in the morning and got to play it for about 20 minutes. Good: -Great tape flanging. Very natural like on my favorite classic rock records. Changing between Sum and Invert of course will get you different shades of positive or negative phase flanging. If you are into regular flangers, you will miss the regeneration knob, but this is totally about the old school Beatles and Hendrix sounds...although easier to coax the Beatles sounds so far. It has been only 20 minutes, mind you. -Delay and other effects sound nice...mainly bought it to be a flanger. -Very bouncy slap back and I usually don't like slap back, but this is the best I've heard. -Turn the Blend knob all the way up with some Wobble for tape/vinyl warping effects. Bad: -The Saturation side. I'm pretty tech savy and have built numerous pedals and amps and fixed to many things to remember, but I'm honestly wondering about the saturation side on my pedal. I tried different guitars and cables quickly, but there is barely any effect at all. With single coils I barely have any saturation even with the saturation all the way up. The volume knob doesn't go to zero like most overdrives. If I use my compressor to boost the Saturation side, I get some overdrive, but without it is totally useless. The knobs have a range and seem to functioning (turning up both turns up the volume and a little saturation), but even with humbuckers I'm not getting anywhere the drive or cool tone of the videos. Very disappointed! I have recorded to tape and understand what the effect supposed to be (and would love to have the effect on the video), and I really roll my eyes a lot when the first thing people say is that you have a defective unit...most of the time it is user ignorance/error. I have a busy day and a half, so unfortunately I won't get to deal with it now. ***Please Deco owners, let me know your experience with the Saturation side. Is mine not functioning as it should? (It would seem so, since it does not at all match the videos.) I'm wondering if the pedal in the videos is overdrive an amp or whatever they use to record. I'm starting to wonder if the flange is worth the scratch. If mine is functioning as normal, it is pretty disappointing to half of a pedal be so useless. I thought I'd be able to use it as a low-medium gain drive or booster between my drives and ambient effects.
