One Control Red Crimson Bass Preamp

I find the description of the controls and saying that "giving deep bottom" adds shimmer to be confusing as hell

:D

In my experience One Control's descriptions in English of their pedals read like pretty good translations from Japanese, but never perfect. They always seem a little like poetry to me.

Though I don't know for a fact what the CRB circuit is doing, I can report how it is to operate its controls.
  • Volume is the master output level
  • Brilliance is quite subtle
  • Gain is very impactful
  • Gain and Brilliance aren't truly interactive, but they act on the source sound relative to each other
  • Scale is king. There are even scales within scales (e.g. Brilliance < Gain < Volume). In my brief experience of Björn Juhl's work, this is a signature BJF design technique. All his Blueberry-based circuits capitalize on that approach. Spence uses this approach in his Vulcan Bass Overdrive. In the CRB, Gain sets the scale of the overall frequency spectrum by setting the bass boost, within which Brilliance seems more effective or less (depending on the Gain setting). Not rocket science, but it is critical to mastering this pedal's usefulness.
  • If you are familiar with the Blueberry Bass Overdrive (BBBOD), then you know that its Nature control is a sort of tilt EQ. In the CRB's sound design structure, you could think of it as being like a BBBOD with no Drive plus a tilt EQ that tilts only in the bass direction. Continuing that comparison, but substituting the BBBOD-based Über Bee OD, you could think of the CRB's Brilliance control as being like the UBOD's Treble, though much more subtle.
It's an obvious point, but: really the only way to understand what these pedals' controls will do for you is to play them yourself. Neither sound clips nor me yappin' about them can convey that experience to you.

And here is a prediction: Most bass guitarists who decide to get a Crimson Red Bass Preamp will reach one of two conclusions about it. Either they will find it to be a silver bullet or frustratingly inflexible.

As with many of the most rewarding and powerful pedals I owned and played in recent years (the Fuzzrocious Broke Dick Peanut Gallery comes to mind), the key to success with the CRB is listening and playing deeply within small adjustments to its settings.

"Small moves, Ellie... small moves."

 
Thanks for the demo! Do you mind cutting one without additional compression ?

You're quite welcome. If I can find time, I will.

Here is a quick improvisation with the One Control Tri Loop, Crimson Red Bass Preamp (CRB), and Hooker's Green Bassmachine (HGB) again. This time there is no compression. :thumbsup:

The setup:
  • Fodera Monarch 5 Deluxe with Klein J pickups >
  • Tri Loop (white mode, buffer always on) >
    • three Tri Loop states: 1. clean, 2. CRB, 3. HGB
  • TC Electronic Ditto X2 >
  • Equalized post for a slight bump centered at 40hz. No other processing.
As before, the order in this demo is 1. clean, 2. CRB, 3. HGB.

Nice! I don't suppose you have had a chance to mess with the Solid Silver Peg?
 
Hey All,

I can't believe I just noticed this thread because I have a lot of playing/gigging experience with the "CRB." Without a doubt, it is in my top two or three pedals that I simply cannot live without (I even purchased a backup...)

Here are my control notes:
  • The Volume knob is just that - an output volume control. It seems rather unaffected by the Gain knob.
  • I've never noticed too much affect from the Gain knob, though I generally leave it around 3:00 (without adjustment). If the design is consistent with some other One Control pedals, it probably works in concert with the other knobs. I would venture to guess that it helps accentuate the frequencies from the Brilliance knob (see below).
  • The Brilliance knob is probably the most useful control - it's the source of my "tonal magic." The instructions call it a "bandwidth control," but in practice it seems to be a sort of low pass filter that comes before the gain stage (granted, I'm assuming this from a few years use the pedal). For example, if you have your Gain knob set to maximum (fully clockwise), but the have the Brilliance knob completely rolled away (fully counter-clockwise), the pedal will only boost a small frequency band. However, by turning the Brilliance knob clockwise, you expose additional frequencies to the accentuation.

Below are my standard settings:
  • Volume: Adjust to setting
  • Brilliance: 9:00 or Fully CCW
  • Gain: 3:00
I generally use it with my trusty, heavily-modified MIM J-Bass. Even with both pickups equalized, the CRB produces quite a bit of bass/body emphasis without the "bark" or "bite" of the bridge pickup. The sound is tremendously dubby/bouncy. It's gotten me very close to the "John Paul Jones meets Robbie Shakespeare" sound in my head. For reference, my basic chain is below (top to bottom):
  1. Fender J-Bass
  2. Boss TU-3W
  3. One Control Crimson Red Bass Preamp
  4. EHX Holy Grail Nano
  5. GK MB500
  6. Markbass NY121 Cab
I hope that helps in some capacity. I might be able to get some sound samples this weekend if you like.

Best!
~Nick "Klaus" G.

P.S. Keep in mind that it does not always play nice with other pedals. It seemed to nullify the effect of my Darkglass Alpha/Omega by killing a lot of the high-end.
 
Nice! I don't suppose you have had a chance to mess with the Solid Silver Peg?

I've got one! It has a gain boost switch instead of a knob; the tone control feels like a tilt EQ and the mid control varies between cut/flat/boosted mids, so there are quite a lot of variations in tone available.

With the gain boosted and my Fender P with flats, I have a hard time deciding whether I prefer this or the Tonehammer... which is saying a lot because I LOVE the Tonehammer's AGS with this bass for vintage sounds, it having fought off some stiff competition over the years!

For very subtle squishy vintage overdrive I rate it over the Blueberry and HGBM anyway. Not tried the little red one yet though!

If I recall, I think I read your post about the "Peg". It seems like an elegant and effective solution. I'm just not sure if it would replace or augment my VT Bass DI. Part of me is very sorry that I ever entered the effects forum.

I'm intrigued and confused by this pedal. Is it just a glorified tone control or maybe an Amp B-15 emulator or what? The few demos on Youtube sound good but is this thing worth $145? Is there a magic sauce going on hear that I'm not picking up on in the demos?
Owners care to chime in? Thanks.

I can't answer this directly, but here's my take in another thread: One Control Sonic Silver Peg
~Nick von Nick
 
Thread Necromancy!!!

Anywho...I finally did something I promised myself over a year and a half ago and direct recorded my P Bass with the Crimson Red Bass Preamp (CRB) on and off. I play a simple minor pentatonic riff on each string (using only that string to get a full neck range). Here are the settings:

P Bass (MIM - stock pickups): Volume Max / Tone Min
CRB: Brilliance Full CCW / Volume Noon / Gain 3:00 (my set/forget values).

Here's my happy li'l setup...
(Bass > CRB > DI > Interface > Ableton)

And here's what I found (the images are from the E-String part of the recording)...

Dry Signal
P Bass Pickup No Tone No Effect.png


Notes:
  • Emphasis on open E is closer to the first harmonic
  • Strongest Signal between 100 and 200 Hz
  • Gentle Rolloff After 400 Hz
Effected Signal
P Bass Pickup No Tone Effect.png


Notes:
  • Emphasis on open E is between fundamental and first harmonic
  • Strongest Signal between 80 and 120 Hz
  • Steeper Rolloff After 200 Hz
I've always noted that I prefer a sine wave-like bass tone, and my ramshackle experiment basically/sorta/kinda' confirms my description. I'm using the CRB to emphasize the sonic territory between fundamental and the first harmonic while rolling off everything outside that range on a gradually increasing/exponential curve.

Tonal magic regardless!

The Crimson Red is quite niche and inflexible, but if the particular niche is your thing you'll love it.

It's hard to describe more than what's already been said but there's something about it that technical descriptions don't seem to cover - it has character and soul. Perhaps that's just me being romantic but it feels like it's more than just low pass filter with a bit of mild tube overdrive, it adds 70's dub/reggae warmth and life to the tone more than I have been able to do by trying a lot of EQ/Preamps/OD pedal combinations....but it's quite a specific tone I'm after, if that's not your thing then you might find it reduces your mids and highs too much and isn't very flexible. In fact, I hesitated to write this review because I wanted to keep the tone secret to myself from other potential reggae/dub bass player competition!

Something I haven't seen mentioned- if you abuse the pedal by sending in a boosted 250hz mid range signal it does some quite nice distortion.

I like this pedal so much that I'm probably going to also buy the One Control Silver Peg even though I have a Bearfoot Queen Bee Blueberry OD on it's way so between that and the Crimson Red I've probably got the sounds covered.

I use the Crimson red together with EWS Bass Mid Control (BMC) and boy does it fatten up a nasal bridge pick up.
If you are playing fast fingerfunk on your bridge PU and find it nasal and thin, this is a brilliant solution.
Also for ballads that needs a huge room filling neck PU, this is it.
The BMC gives the tone a bit of poke and stability.
A true secret weapon.

I agree with the BMC. I bypass my bass' on-board eq, and use the BMC with the Zoom MS60B's SVT modeler and Polytone MiniBrute III cab sim...ROARING tone.

I really affectionately nicknamed this pedal the "Dub Switch." It is the sound in my head, but definitely a one-trick pony. The only reason I have ever taken it off my board is when I need...well...more tricks.

Time to re-zombify this thread (is 7 months considered "deceased"?) I had a CRB a while back as a stand-alone preamp and did not dig it. It was way too dark, though it's an intriguing concept if you want a dark, mellow tone. But I really love to be able to tweak my mids. It's not what I wanted at the time, so I passed it on.

Well, I totally impulse bought one for a second time a few weeks ago, because I actually want something right now to give me a darker, more vintage tone. This time around, I'm in love with it! I don't think it's right for everybody or every gigging scenario. But if you're into warm, fat, bassy tone, this has it in spades! (When used in conjunction with other things.) Sure, it can very easily do that warm, fat dub tone, but that's not my bag. I use this in conjunction with other preamps and eq's with which I can boost mids, further sculpt lows, etc, and what the CRB brings to the table is fantastic. I have other pedals that can boost lows (amp sims, Broughton RFE, dirty boosts, etc), but the CRB really boosts them in a fat, powerful way. I don't really know how else to describe it. Basically, Broughton SVPre (Ampeg amp sim), with which I can boost and sculpt mids and add a tiny bit of lows, into the CRB with the brilliance knob around 3:00, is an incredible fat sandwich. Makes the walls rattle. But it's not an out-of-control boom. If you dial that brilliance knob back much below 3:00, like 12:00, it can get really subby, dubby and muddy. But with judicious settings, and the gain around 12:00, running it at 15v, it is amazing. The CRB does things to your low end that no other pedal I own can do.

And it's definitely not just a LPF. Because I have a Broughton HLPF, and cranking the LPF side of it yields similar but not the same results. The CRB does more than cut highs and darken your tone, IMHO. It darkens slightly (if you want) and boosts, adding sheer power in all of the right places. I do think you need somewhere else in the signal chain to dial in some more mids, but if you can do that, it's well worth your time. I'm a fan.

Potential dub competition here.:laugh: As explained in another current thread, I'm trying to fatten up my dub dedicated Pbass that can't quite achieve Flabba Holt type fatness, at least in my hands. I'm quite intrigued by the Crimson Red pedal that could be the ticket but before ordering I'd like to ask you guys if you think the AMT A-Bass tube pedal is somehow comparable to the CRB and if so which one will deliver max fatness.

My setup: Fender 2008 Am.Std. Pbass with PV63 pickup, Dunlop flatwound strings, Markbass Little Mark Vintage amp head, Markbass NY212 cab. Cheers

PS. There is a newer version of the CRB available but I think it's just the artwork that is different.

The Markbass Amps/Cabs get a solid dub sound. And yeah - the art is the only change to the CRB.
