5k rolloff in a DI

#61
Tone Hammer is phantom, power supply, or dual 9v battery. Please look at my graph again. Very little coloration there at all other than the roll off.


Jimmy, the Tone Hammer isn't nearly as colored as the VT, which as you know is highly colored. You have to really twist the knobs to get that kind of color out of it. I wouldn't steer you wrong.

It seems that Jimmy wants a completely transparent solution. He just wants to whack off the offending frequencies before they get to his amp, not add another "effect" to the tone of his signal.

My question though, is why do you think the Tone Hammer is an effect? If you don't drive the preamp, it is essentially what you are describing.

The EQ on the Tone hammer is probably great but it won't have the precision or slope to mimic the low pass effect of a loud speaker. He needs a cab sim not an eq.

Look at the graph again. The slope is more than "just EQ" at about 12 to 15 dB per octave. That's what any cab sim I've ever seen does. The AGS on the Tone Hammer is exactly that...a vintage loud speaker emulator plus an additional gain structure that allows you to drive it in to overdrive if you wish. I don't want to derail this thread any further, so just clearing the misunderstandings at this point.

Fair enough. The graph won't show up on my phone. I've never seen anything from Aguilar claiming it had a cab sim or I would have looked at them when they came out.

Maybe because of the phrase "very little coloration" in a previous post? That indicates a non-zero amount. But it might be acceptably low to the OP.

A lot of this would seem to come down to cost and size of the device.

You could try a sansamp classic or gt2 but set it for low gain so they don't clip.

Many brands make decent cab sims. If you don't feel like searching I'll post some links tomorow.

The Sansamp Para Driver would work for this application. You can set the blend knob all the way down to turn off the tube emulation, and stick the EQ knobs at noon.

That would give you a flat, linear response up till you hit the 5k LPF speaker emulation. I scope-ed my Para Driver over Thanksgiving out of pure boredom, and it is in fact completely flat out to 5k with the tube emu bypassed and the EQs at noon.

This pedal might be a bit overkill for just doing a LPF, but if you happen to have one sitting around, it'll work nicely.

"Cab Sim" is just a misnomer any ways. There are a bazillion cabs out there each with a different frequency response, so anything that changes frequency response in a pedal to mimic a cabinet is a "cab sim". Vintage cabs had no tweeters, and typically the high end rolled off very quickly over 5k. Most all cabs, even modern ones, have sharp attenuation starting around 60 hz give or take. So the Tone Hammer with the AGS on is very much a vintage "cab sim".

Agreed, but by color I mean EQ, and as you can see the EQ changes with the knobs at noon are in the +/- 1 or 2 dB range, which is next to nothing, and can be flattened out very easily. I could gladly post flat settings for the Tone Hammer with AGS on.

The Tone Hammer without AGS has more coloration IMO since Aguilar slightly attenuates that very high treble, and they boost the low mids. That provides Aguilar's trademark warmth while still retaining a full-range spectrum. That is the white line on the graph I posted.

Anyway, this might not be what Jimmy wants to try. I was just offering my opinion on something he could look at. I'll say for clarity's sake that IME that simply rolling off treble at 5k with no other changes usually results in a very muddy tone. I think tightening the low end is critical to get the right tone. Even further than that, the remaining frequencies that are intact have to be sculpted a little to get the right presence, either by dipping the upper mids a little around 750hz, or by accentuating a little bit of that 2.5khz presence peak to keep the tone sounding crisp. The Aguilar does that every so slightly with the knobs at noon. It's a very minimal coloration, but it can be "undone" if you will very easily by simply pulling the treble down to 11:30, and boosting the lows to 12:30.

I know the op wants a simple, no extras, lpf - but I'd also like to suggest my favorite piece of gear (whether it meets the op's criteria or not) in true talkbass fashion! I suggest my amp head road case! It weighs about 45 pounds. Just beat the uncooperative foh engineer with the lid for a few minutes until he/she agrees to turn the frickin' treble down on your dang di channel!!!!!!

;)

Solved. Move along now. Also, get a lawyer.

Maybe, Sam. Looks like it's designed more for guitar but I guess he could tweak it for bass, though. But it's definitely more in the direction of what I'm looking for.

I'm sure it would be a simple and inexpensive mod for sfx. I am experimenting with modding my JDI's speaker sim. basically lowering both the HPF and LPF points so that it becomes more bass friendly. Hope to have it back soon to give it a try.

Jimmy, this is a little off from what you originally asked but since you love the B15, I'd think running a Catlinbread SFT through the REDDI would be fantastic sounding. The SFT is wonderful for that B15 warmth and feel, and it would give you some Baxandal EQ control on top of that. I LOVE my SFT with a P bass with flats.
