Double Bass High Pass Filter questions

[Slaphound]

I'm looking at using a High Pass Filter, HPF, to fight feedback. I play in a loud rockabilly band and I have the K&K pre Rockabilly set up. I looked at this page which I believe is F-Deck.

So I basically want to know if having the volume control on the HPF from F-Deck is useful/necessary when in conjunction with the K&K preamp.

It's not needed, but since the fdecks without a volume knob are plastic, I'd step up to the metal bodied 2M just because it's more rugged. It also has an LED to indicate the battery is good. The actual HPF circuits are the same in both.

I have the bottom o’ the line FDeck, battery powered. It works like a charm. I hung it off my tailpiece until I went wireless. With the Line/6 G10 it screams bloody murder. I use it, but it has to sit on my amp now.

Another advantage of the FDeck product is the builder. He is here and is quick to respond to questions you may have.
The phase switch can help eliminate feedback too

I find it helpful to have the one with the volume control. From time to time, if I’m playing in a really minimal equipment situation, I could use the F deck by itself as a preamp since it has adequate input impedance

I don't see a downside to having the volume control. You can keep it maxed and forget about it, and it will be there for the future - if you are ever in a situation without your k&k, or someone borrows it, or whatever.

The volume control might be redundant if you are also running a dual channel unit to blend two pickups.
I would still recommend the next better unit for the tougher construction and the battery light.
If you ever find yourself using just one pickup, IME the volume control is absolutely worth the slight extra cost.
I wound up upgrading from the basic model, would 100% go with the Series 2M from now on.

Another great thing about the fdeck with a volume knob is that you can mount it under the tailpiece and have quick easy access to the volume knob as needed for arco / solos.

Where can the Fdeck be purchased?

Its order online. Check the link in my first post in this thread. It's there.

I’ve used both versions with and without the volume control. Both are great. I found that the series 1 FDeck pre best for me when dual locked to the back of the amp and wired into the FX loop. That left only two knobs to worry about: the setting on the HPF, and the master volume. Less attention on futzing with knobs led to more attention on making music.

I approach passive & buffered volume controls somewhat differently. IME the latter can be very handy for matching levels sometimes, while the former is mostly for volume swells and/or muting for breaks.

I have one of the plastic HPF-Pre, and I've never worried about it's ruggedness. Mine is the (now discontinued) Series 2 with the volume knob. I always velcroed it to the tailpiece, so the light weight enclosure was a selling point. Depending on the pickup, I also found the volume knob useful when switching between arco and pizz.
