I was ay least smart enough to figure it out. lol
I had found it at work today but they block anything like this. When I got home I couldn't find it again.
Thank you, mbelue! |

| | | | Just looked at the site and really would like to know if I'm OK using this in an effects loop. I see it will take 6 volts P-P, but I don't see the need for a 10 meg ohm input impedance in this situation. I suppose I could put a 600 ohm resistor inside the 1/4" male phone connector going into the input? Or would this even be necessary? I figure putting it in the effects loop (or in between pre-amp out, power amp in) would eliminate all the subharmonic 'junk' very late in the chain.
Should I just hook it up after my wireless receiver and forget about the effects loop?
Thanks. |

Thanks. | Yes some people use these in effects loop. When in a loop, you are effectively losing the impedance optimization feature that is beneficial for piezo pickup. So for magnetic pickups this is a non issue. You still have the phase and HPF features. |

| | | | I understand about the loading effects on pickups because I built a few FET preamps. I just wonder about noise pickup if I'm running a cable from my effects loop to this HPF, since it's input Z is so high. Guess it doesn't matter since my effects loop is putting out a low impedance anyway.

| | Registered User | | Join Date: Mar 2007 Location: New Zealand | | | hi all, i have a query that i couldn't quite discern from the website and figure some users would know:
the volume control on the series three, is it a passive volume control, or does it also provide a boost? i ask because my setup is very sensitive to volume changes, as i run my (tube) amp at maximum and use multiple dirt/fuzz pedals and am hesitant to add another volume control to the mix! |

I emailed Francis about a belt clip accessory for my Series 2. He sent me this clip that was very easy to install. I'm looking forward to being able to adjust my sound/volume from my belt. Great product, customer service!

That's why I'm really happy that the fdeck series IV sports Bluetooth wireless control to a tiny controller that you can clip anywhere. Okay, I made that up-- no truth to it at all. Still, it's not a bad idea.

It's a unity device, it's a buffer, it's a phase-reverse switch, it's a variable HPF, and there's a volume knob you can use to reduce the signal strength. But wait, there's more...  |

| | Registered User | | Join Date: Aug 2006 Location: Ann Arbor, MI, USA | | | I received my HPF series 3 in the mail today, and am very impressed by the bed room tests so far. Through my Crazy 88 my p-bass has always felt... squishy. No longer! Also my Double Bass is starting to sing and I'm really excited to try it on the gig.
I have a couple questions:
My first question was going to be whether the series 3 boosts the signal at all.
Reading back through the last couple pages I discovered that was already answered: No
At the same time I feel like the volume I'm perceiving when plugged in is increased, is that just a psychological effect?
Is there any (practical) danger of clipping the circuit in the device?
Where have you been placing your HPF when its in use? Top of the amp?
Finally, in a similar vein, what settings have people found helpful on the gig (with the series 3)? Obviously my bass is my bass is my bass, but I'm just curious.
Many thanks to Francis for what seems like will become an indispensable part of my toolkit!

| | Registered User | | Join Date: Apr 2009 Location: Toronto, Ontario, Canada | | | I have a couple of questions about the series 3.
The series 3 has a fixed filter at 35hz and 12db/octive slope. How fast do the frequencies below 35hz drop off? That is, how steep is the slope?
Also, the series 3 has a second filter that is adjustable. If the second filter is set at 35hz as well, what is the practical significance of having 24db of cut rolling off at 35hz? Does is settle down those sub frequencies even more? |

You are correct about the slopes. Everything below 35 drops at 24 db/oct. that 35 hz point is determined by the adjustable filter. If you set it at 35, then 17hz is at -24. If you set it at 70hz, then 35hz is -12, 17hz is at -36. Etc. etc.
To answer your question, kjung has already said it well: the series 2 filters out most of the sub lows. Series 3 filters out all of them. Side by side they do sound a little different. I prefer series 2 on acoustic instruments like my upright and U-Bass. The dynamic character sounds a little warmer and I like some sub lows at those medium and low volumes. Series 3 is wonderful for my electric basses and at very high volumes. Mine lives with my electrics. |

I do not play any DB, so I guess the series 3 would be best for me.
I have been exploring ways to get rid of sub frequencies in my setup. I use to have Trace Elliot head that had a 30hz graphic eq slider that really helped tighten the DI sound to the PA. There are certain PA systems that put out some serious sub frequencies in my area, which makes any bass sound muddy.
Another option would be an eq pedal. Whirlwind makes one with a 20hz slider that you can cut that I have been looking at. However, this fdeck might be the thing I'm looking for and at that price you can't go wrong. Quote:
