I only play electric bass and would love to try the HPF with my older SWR head; a few questions:
* Would 24 dB at 35 Hz. (or higher) ever be too much filtering?
* Would 12 dB at 35Hz (or higher) ever be not enough?
* Do any of you really use to distinct filter frequencies and is it that big of an advantage?

My plan is to use the device either between the bass and the amp, or more probably in the effects loop (and with other amps as well).
Not sure which model is the best fit and if I would ever want the 24dB or the ability to have 2 frequency points

[kurosawa]

1 & 2. Maybe you are thinking of 24dB vs 12dB as amounts of attenuation. They are rates of attenuation (24 is twice as steep a slope as 12). If you don't have them both on 35, you have two rates of drop-off, one beginning wherever you set it, the rate doubling at 35, not two drop-offs.

3. I think the idea is that increasingly from 35Hz on down, freqs become destructive of drivers and not much else. I've been breaking a driver in with Bareface's 25Hz file and whatever it is, it ain't music.

And getting the extra filtration means if the lows are rolling around the hall, they can be reined in. Just go up in frequency until they go away. It's not like you pick a "distinct frequency," your ear picks it.

It may look like all one thing, but it's the job that defines the tool, not the tool's shape. So that's a pair of very useful and distinctly different tools in one box.

I love that Leo quote, and it's something Nino Valenti and I were just talking about.
I've never broken in a driver by other than playing it.....

Let me ask the question differently.
Based on the experience of those who have tried the HPF's:
For electric bass as speaker protection, should I order Series 1 or series 3?
or
Series 3 would never be a disadvantage
or
Series 3 just offers more options for different rooms and no one can decide what works best for you.

More options allow you to set your rig for the room better. It seems to me that the steeper the slope allows one to have a more targeted approach to the filtering, thus allowing more control.

Thanks
I finally read ALL the threads, visited the website, etc.
Sounds like any will work well for an electric bass application with an untamable amp (SM400). Would like to save some $$ with the series 1 but realize the extra filtering at 35 hZ. and the ability to also filter at higher freqs could be advantageous.
Anybody with a series 1 with an electric application feel that the series 3 is overkill?

I think Leo was WAY more sensitive to tone than folks give him credit for. I think he just didn't mess with it much, as the individual plank was a variable he had no control over as a factory kinda guy. The stuff he DID mess with, no one messes with. I mean, who asks for a custom bass with an EB-3 pickup scheme, or a Rickenbacker pickup scheme, or a Mosrite, Dano, Wilshire, Hofner, Sadowsky Modern, Hagstrom, Guild? If they don't tell the builder to do his thing, pretty much they ask for a P, J, PJ, MM, or some variant. Man knew his stuff. For each of his three basic designs, he probably threw out hundreds.

Yeah, I'm in a townhouse, trying to be considerate of the neighbors. I figure if I can break it in only when they're gone, judging by when their car's absent, there will be peace.

Finally got an agent and a day gig that accommodates musician's hours, instead of those 12-hour night shifts I previously worked.

My .02:

Go for the Series 3, with electric. I've often been glad I could mess with the slope of the second filter--kind of tuned my rig to the room. Well worth the few extra bucks, IMO.

Sounds like 12dB of 35 Hz just isn't enough on some occasions.
As I understand it, the Series 1 continues to have a 12dB reduction at 35Hz. even when it's dialed up to say 50Hz
In this example, the Series 3 set the same way has 24dB of reduction at 35Hz. and (with this example) 12dB at 50Hz.

Or, do I have this wrong?
Thanks for your patience.

Any of the models will change your life with that particular head. Most heads are pretty well controlled down low, and a Hi Pass filter becomes more of an additional tone control than a necessary hi passing of sub bass. Not so with that SM400, which pumps massive sub 30hz sub bass out. Just awful IMO, but easily fixed with a true hi pass set around 35hz.

I'd go with the III if you can afford it... totally will eliminate the sub bass issue of that particular amp (literally the amp with the most severe low end control issue I've ever played or owned), and the nice metal case is a bonus.

You will be amazed at the increased output you will get (again, with that particular head), and the drop of 'speaker pistoning'

HIGHLY recommended. I had to carry around a rack mount Rane hi pass with that head back in the day. The FDeck is smaller than a tuner pedal!

I'm gonna pick one of these things up once I get the moneys. No need for a DSP... very nice!

Thanks Ken,
Curious to hear your opinion on:
Is 12dB at 35Hz enough?
And if so, wouldn't a series 1 be pretty close to a series 3 at say 50Hz with the only difference being 24dB of filtering at 35Hz?

BTW, I'm sold on a series 3, the metal case and headroom is a deal for $50 or whatever it is. Just curious about my question as well as if it would offer much for use with an SVT head into a full range cabinet (like a Berg HT322).
TIA

I went with a Series 3 because it has a standard 9v Boss-style plug. I don't like to use batteries. They always go dead at the worst possible time and they are bad for the environment.

I'll let FDeck answer that one (or others with more technical backgrounds).

I can tell you that the Rane I used back in the day was variable, and -12db. I had it set at 30hz, and it totally took care of the issue with that head for me. So, my guess would be that any of the models would greatly improve that head. I personally would just save your pennies and hit the III. No downside to that other than a bit more cost.

Fdeck, I'd love a hpf for electric bass, similar to how one would use a Thumpinator. Do you have plans to ship outside of the US? I'm in the UK.
