Compared the Ibanez FL303 (late 70's I believe), FL301 (early 80's, 18v), FL301DX (late 80's with 9v battery), and FL9 (90's). This is the first loop. Sounds recorded identically and normalized for accurate comparison.
FL-303 is the best for me, despite the horrible settings on this video. But it seems a common plague here in RU-vid, where no one can show a demo with low speed settings, which is the best way to use such effects as flangers and phasers. Instead, you can hear a lot of dull sounds with all the parameters set around maximum, despite the feedback noises they generate.
Me and my guitar tech person are having lots of trouble powering it up with the adapters like what you have on the far left ? Any idea how to power it up and get the effect work?? What did you exactly do to power it up ? Any advice? Thanks Austin
