I have loads of pedals, but if you'd like transparent flanger, I have the Strymon Orbit and it's just a really great transparent sounding flanger with loads of settings. It's got TOO MANY settings for me , so someday I might sell it but I very much love it.
I've had a Mutron Flanger which was 1 of the coolest pedals ever, (worth a mint these days and rare as hell ) and an ADA , and used the old Grey box 4 knob MXR Flangers for years. . But the Strymon definitely is great.
I have a Sobbat Phaser, Boss Ph2 , and PIGTRONIX Phaser/Envelope Filter, had the Ada Final Phase. . I think the Pigtronix is about as cool as it gets
