Yamaha FL-01

pedal dating from late 80s 70s/début, so analog, and surprisingly true bypass (the signal is not switched off when not feeding it).
4 controls, even on later versions of the same brand: feedback (dosage effect in the signal), speed, depth (amplitude), and manual (I think it controls the note up which the effect down). The manual and depth are quite similar, I do not know to explain the difference.
The pedal is powered solely by 9v battery, but I connected my bp without Big John, with 9v battery adapter cables, no pb particular breath for the moment.

UTILIZATION

Not very complicated to use for basic use: if you want a classic flanger, the settings are all alone, everything has MIDI and then assayed by groping each knob.
But this pedal opportunities quite varied, and there better vauty spend time to become familiar with the settings, especially the pots and depth manual. The speed and feedback, this is fairly standard.

SOUND QUALITY

What I love about this pedal is that besides having a very beautiful and colorful hot flange, it self-oscillates very well, and after what I saw on the net, it is well known for!
For clean sounds, using a small dosage effect, we botient a very bele color, whether to have an alternative to the chorus, or to have more typical effects of an approaching his sitar. Distortion in (I place before a Russian big muff V8), we obtain a good spacial sound psychedelic! We can all play with the knob configurations (notably the manual) for some dissonance can use.
It may also, by setting the depth very low, low speed and very strong feedback, get a bumblebee food a little what we play a guitar, but is quite usable. Aini can adjust the drone notte by turning the knob "manual", which is very reactive.
So full of possibilities.

OVERALL OPINION

I use it for some days, but it did not take me long to get an idea of ​​the use that I wanted to do. I love the sounds psyche has Ufomammut obtainable, coupled with a delay, as the quality of its classic flange.
I have no clue about the manner in which the price will evolve, I think this model is nearly equivalent to may other flange of this pédiode (other yamaha, korg, etc.), so he will address his fans vintage. The absence of power supply is a little painful, but with this pedal, no problem to connect it to the mains, provided you have a quality power supply to protect the épdale and to avoid hiss or noise.
