i don´t think i can play the low B on a guitar so easily

also, it would sound way different

I was just razzin' you a bit!

i know, i´m alright

question remains (i was serious)

I love my original fdeck HPF pre though I haven't tried the newer version.
It is by far the best investment I've made in the last 10 years to improve my upright bass tone.
Keep up the great work Francis!

if i got it right, there´s a 33k resistor + a 100k pot for the cutoff point.
using a 250k pot would then result in a cutoff range from roughly 35 - 300Hz.
but would changing the pot (= setting it to a higher cutoff point) have any side effects on the circuit operation?

no one?

I think the reason no one is responding is no one really gets why you would want to get into cutting frequencies that high.
They're more or less what makes your bass sound like a bass. IMO.

I use my hpfIII with both electric and double bass, and have never really wanted/found a use for much higher than 80-ish.

ymmv of course.

When ever I read 'pot' on a music forum, I am not thinking of knobs. I am of no help with that question.

i think no one´s playing in a band with 2 bassists, going up and down a 7 string neck

or I could use it for entirely different instruments.

but it´s not important why I want to do that, I wanted to know if it´s possible to do without further adjustment of the circuit.
seems like i just have to hope it sounds okay after changing the ... potentiometer

maybe you just want to add a graphic EQ to it. once the sub lows are cut out the rest of the signal should be manageable with EQ

miiitch · #**692** 01-18-2013, 12:42 PM

oh, i do have quite some EQ force to play around with ... the bass knob on my tube drive, the HPF right after, a 4-band semi-parametric and another bass knob on the amp.
but i want to have some more options

lol, how about a few graphic eq pedals in the mix?

Just a few?

If you want a another option- the Alembic SF-2 is the bees-knees. You could set one filter to HP, another to band pass for mixing in mids; run the filters in series or parallel. However, the most economical solution would be to utilize the FDeck with your existing rig. With a little filtering and subtle eq-ing, you should be able to get the desired result.

Played upright at a jazz quartet gig last night. The room is ok, the sound sucks and it is a nightmare for bassists. The fdeck makes it manageable. But I already knew that.

I played the first set with the series 3, into my Genz shuttle. It was pretty ok for that room. For kicks, for the second set, I swapped out for the series 2. Same tone, but I don't know, dynamics were warmer. I have no idea why, but for the upright, series 2 sounds better to me. I kept thinking about that "musically forgiving" thing vs. the "hard clipping" thing, and I know I was nowhere near overloading it. One other thing is that series 2 sits up in my bow quiver, and it is easy to adjust on the fly. I actually was tweaking the filter per song, as well as volume for different parts of songs. I like the extra gain on it too. Just my observations.

Because a 25 Hz slider on a graphic will cut 12db at 25 Hz, with a portion of the neighboring frequencies on both sides sloping down to it from "flat". So now you got 25hz at -12db, but where is 15hz? At zero? -3db? It's like you put a steep canyon in your frequency spectrum with 25 being the bottom. It will probably help.

The Series 3 gives a steep corner At 35 Hz that rolls downward from there at 24db/octave. When you turn the knob up the roll off corner gets higher and gives you a -12 db/octave slope and still a -24 slope from 35 on down. It gets rid of everything the lower you go.

The last 2 nights I had my F-Deck set about 2:00 (60ish Hz?) and only barely noticed an audible difference. Not so boomy and a lot cleaner, with no loss of balls or punch. When I cut 31.5 on my graphic I lose low end that I want to keep. And it makes it sound less ballsy. Just IMO and IME.

Okay just to revisit this a little...

I am trying to make my pedal board super small and I am thinking that perhaps I could eliminate my Fdeck HPF (for the time being).

With my eq pedal I have 40, 63, and 80hz (etc) available plus or minus 15db.

Can I cut the 40hz by 15db and bump up the 63/80 to cut boom and maximize upper bass punch without gutting my low-end? The amp for the particular endeavour would be the gk mb800.

That might get you what you want but it will really color your bass tone. That's one of the remarkable things about the HPF 3, it still allows your bass to sound like itself yet cuts out all the in audible stuff. Any time I've tried to simulate this with a graphic EQ, I've noticed the dramatic tone difference from my basses natural sound. Not necessarily a bad thing...

I fully support your two bassists band and the modificstion of your fDeck- I would just give it a shot if I were you as it is a pretty cheap experiment. I've done a couple bands with two bassists, but I was always the "low" bass! The other bassist I played with would play his Jazz through a 50 watt Marshall guitar stack, so there were little lows to worry about...

sunbeast · #**700** 02-10-2013, 11:41 AM

Curious- I finally just got an fDeck Series III myself after loving the Series I I had but wanting to get the more "electric friendly" version. Anyone tried it with an Aguilar DB750? I'll be curious to see if it tightens that amp up a bit without making it lose some of its glorious punch! I am also excited to use it with my Mesa Walkabout having heard the successes of others with that amp.
