    Well I bought into the HPF.... ( Braughton ) over the Holidays. Had to find out for my self ? Been using a Behringer parametric EQ with low cut filter. This worked OK, but the Braughton got things much tighter on the low end. Hey what took so long? I am now drinking the TalkBass Cool -Aid [email protected]#%$^&*&. :smug:

  2. It's only Kool Aid if it contains snake oil, you are good to go.

    Best HPF experience to send you on your way. I got served up a 12'' SWR combo as backline. I have a 5 string and I use it. B bombs would have blown it up but the trusty HPF let me play away unconcerned after a quick dial in.

    The trick is to bring it up until it doesn't sound good any more then nudge it back. Turn it up and see if it still sounds good.

    If not you have to choose between less volume or less lows. You could bring more rig next time but don't blow away the FOH getting your rocks off!

    I’m using the Broughton HPF/LPF. I can’t be more fallen in love with it... Simply, effective and versatile!

    What about just buying the Mesa Boogie WD-800 with the HPF on board? Any thoughts on that?

    $$$ but, if you've got them, why not. Great equipment, great support and a great designer who is a TB member and really listens (@agedhorse)!

    I've had two fdecks and a Broughton (and the HPFs in the Fishman Platinum Pro and Platinum Stage preamps). Haven't used any of them with electric bass since getting the WD-800.

    And you shouldn't have to! I purchased my Broughton Always On because my Rumble 200 didn't have an HPF. I haven't used that either but that is due to COVID shut down.

    Actually, from my understanding the Rumbles do have an HPF built in, but it’s non adjustable and not quite as noticeable or effective as the Broughton/fdeck/etc. I believe it’s for speaker protection, someone in the giant rumble owners club probably knows the details on that.

    You are correct. It does not provide for adjustments to the room and it is "proprietary" which means they do not have to provide details as to what it actually does. Therefore, to me, it is not a customer adjustable (useable) HPF, IMHO.

    Just because the customer can’t adjust something doesn’t make it unusable. Often, the customer doesn’t have the necessary information to understand how best to us a feature like this, especially since the speakers in a combo are designed hand in hand with the amp.

    For example, even in the designs that use an adjustable HPF, most also include a minimum non-user adjustable HPF setting in addition to the adjustable part of the filter.

    I'd agree that a fixed versus adjustable HPF has much less utility (e.g. added dimension to tone shaping options, problem solving in acoustically challenging venues, etc.) for many of us. However, if given a choice between a head with no HPF and one with a HPF operating at a fixed frequency, I'll take the fixed option. My experiences with the original (Steve Rabe days) SWR heads taught me some lessons there I will not forget.

    Even if Fender does not provide a lot of design transparency, I believe they have a strong engineering department. I am confident that they made good choices with their fixed HPF design to preserve headroom, protect speakers, and not negatively impact low end performance.

    Agreed. I am just saying that I like having an adjustable HPF. Having a fixed one for protection is fine by me!

    hot take:

    Like the HPF and think it helps? Use one!
    Dont think it works/isn't worth it? Don't use one!

    Easy :)

    (coincidentally, apply said logic to pretty much everything)

    Sounds good to me but, if everyone applied that logic, the TB threads would be empty :roflmao:.

    There's an adjustable EQ filter in the Zoom B1 Four that can be set to act either as a LPF, HPF, LoShlv or HiShelv filter with an adjustable slope from -1dB/Oct to -12dB/Oct, the latter pretty much being the standard for LPF's and HPF's, thats about as cheap as it comes, and I would dare claim for something as relatively simple as a HPF the quality should be as good as any digital HPF on the market, and even though it is a multi effect it is still slightly smaller than about 2 Boss sized pedals pressed agains each other side by side.

    Another slightly more expensive option, but still relatively cheap compared to most other HPF available on the market, is the optional HPF, fixed at 40Hz, build into the ART Tube MP Project Series tube preamp, though it would require of you to run it through the preamp, it utilizes a starved tube plate though, I think I read somewhere around 70V, where the tubes are designed to run at much higher, around 200V to 300V plate voltage, but I use it myself as the preamp in my "ampless" setup and think it sounds lovely.

    Contrary to common believes the starved plate voltage actually makes the tube color the tone more than what is the case at higher plate voltage, though the character of the tube does change some at lower voltage, also be aware that the cheap Chinese stock tube sounds pretty crappy, so if you go this route I would advice swapping it out for one of proper quality, personally I use the EHX 12AX7-EH preamp tube for my Art tube preamp.

    As said I love what it does for my tone, and I do in fact have the build in 40Hz HPF activated too, which seems absolutely perfect to me, tightens up the low end and makes the tone clearer.

    Well, I prefer simple designs and not a ton of pedals and switches. It's bass after all. Just a simple HPF is fine.

    Agreed...that's why I decided on a Broughton Always On. Depending upon room conditions, I can adjust it or remove it.

    Yep. Ridiculously cheap, very small, sounds good, fairly easy to use.

    The only hitch is that the HPF takes up one slot of a patch, and the LPF takes up a second. If you want both, that will use up 2 out of 5 slots in a patch.

    I believe many multi-FX units have something similar. E.g. the Boss GT-1000 Core has a para EQ that includes both an HPF and LPF.

    That looks nice but that's a lot of money. WD800 might be the way for me to go. I was going to get a quilter bb800 but lacks a lot of EQ features, no ground lift or HPF. I play heavy metal, hard rock so hoping the WD800 is good for that. Plan to throw a sansamp in front or a Ged Lee YYZ pedal.
