Hi Folks~
A while back I bought a used BF-2. It has a knob missing, but worked well. I ended up using a couple of other flangers for a while and but the BF-2 in a drawer in my desk. That was a couple of years agao.
The other day I took it out, powered it up and...nothing. Any suggestions on what to look for and anyone know where I can get a knob (if I get this working!)
Thanks,
Brian |

Hello!
Did you use battery or power supply?
I screwed earlier up by using a psa adapter on aca pedal.
Otherwise, need more info.

Did you look inside? Anything look bad? |

Hi Folks, thanks for the help...pedals 4 pv - re: the knobs, would I just tell them the model and serial number so that I got the right vintage knob?
Re: the BF-2, I have only used a battery. I'm going to open it up today and look inside, bt I can already see there are mismatched screws on the bottom...uh oh...
Thanks fpr metnioning things about psa and aca - I was just noticing that myself, last night...I just bought a PSM-5 (which is psa, right?) so that means I can't use it with my old aca pedals?? Oh turd... |

as far as mixing PSA with ACA i dont think theres a problem. ive been doing it from the start and have never had a pedal malfunction. there is a rule though about putting a PSA between 2 ACAs or something like that. i dont know exactly but im sure someone on here knows and can clear it up |

Hey
As I understand it, you can mix and match aca/psa pedals as long as they share common ground(ing).  That just means that they are connected together with patchcables between them(which they usually are anyway)
Still, if you used just the battery, and it still is no life, well ...
I would start checking for corrosion inside since it just has layed unused for years. Did you leave it with the battery connected?

Hi Ken. No, there was no battery inside. I opened the BF-2 up and the only thing that looked funky to my eyes was a couple of the wires going to the "manual" pot. I've tried to show a picture here, and if you look closely at the brown wire in the center, there's a black "burned" looking spot a few millimetres up from the connection. The white wire looks simliar.
BTW - what is supposed to be in the bottom of the pedal between the pcb and the metal baseplate? When I opened this, there was just a piece of paper towel separating them!

Just took a look at mine, and the brown wire (pad 10) is to the lug towards the center of the pedal, and the white one (pad 9) leads to the center lug of the Manual pot. Someone rewired it wrong in the past?
Paper towel? like real paper towel (scott, bounty...) or thick paper
The thick paper was the old way of insulating it, the newer ones have plastic. Get some mylar or thick plastic and cut it to shape
Good luck |

Yep. I got a new knob for my MIJ OD-2, no problem. They probably have the insulator plate for the bottom too.

Thanks folks. Yeah, it was paper towel, like Bounty. I know what you mean by the mylar and we have tons of it at work.
The only thing that confuses me about the wrong re-wiring is - it used to work just fine? |

Hi Guys
Christo is that pot wired as a variable resistor(2 wires), & not a pot (3 wires)
That would explain why it WAS working OK, because on a (2 wire) variable resistor, it doesn't really matter which way around the wires go.
It was hard to tell from that posted pic.
Regards Dr. Bob |

Thanks to everyone for your input. Combined, it all led me to a happy conclusion!
Christo & Dr. Bob, you were both right about the pot wiring. Turns out the 'manual' pot was working backwards - just never noticed that before!
As for the "problem", well, whoever had reversed the wires had put that oil-soaked paper towel in there with the best of intentions. I will say it kept the pcb and metal bottom plate in great condition, but what I think happened is that all those years in the drawer, opening and closing, sliding a little one way then the other, must have allowed some of the sharp solder points to dig through the insulator and come in contact with the metal plate. Last night I hooked it back up without the bottom plate et voila! - nice thick flanging, and a reverse "manual" pot...
So, since my new BF-3 just arrived yesterday... anyone want to buy a brand new BF-3? Or the BF-2, I guess, although I think I prefer it!
Thanks again, all |
