Bass Players of PPCB: Help me plan and fill out a new bass rig!

So I don't know if this is the case for anyone else here...but I am a pretty big effects nerd when it comes to guitar but fairly vanilla and/or inexperienced when it comes to bass. Which is a bit ironic as I got my start as a bassist and have played it for longer and still to this day am probably split 60-40 between guitar and bass playing (and sometimes that swings to 40-60 :P)

Anyways when it comes to a bass rig I've more or less always made a guitar board my first priority and then just try to find places for it to pull double-duty on bass when possible. That's worked out okay in the past. I used to have my whole rig based around an HX Stomp which was a GREAT little bass machine but I've since moved on from that - the guitar side of things is all sorted out, but now I'm looking to make a standalone bass rig as well.

So here's where I'm at for the moment. I don't use a ton of effects on bass in the first place, though am branching out a bit and do like the option...
With that in mind the heart of it at the moment is a Line 6 M9. Typically I use this for a few simple effects like compression and octave (I think the octave is surprisingly good on bass tbh) as well as very rarely modulation. It has a built in noise gate which is nice too. I've got the expression pedal to go with it but it doesn't get used a ton.

Beyond that I've been looking for an excuse to try out the Equilux/Equinox build and think that would be a pretty handy piece to have on board.

With those two "core" pieces out of the way I've really just got two more considerations I'm looking at for the moment.

One is an ampsim/preamp and the second is some kind of direct box.

When it comes to Amp Sims / Preamps...I pretty much am always playing direct to board/PA. For those of you in the same boat, do you bother with any sort of cabinet simulation at all, or just go preamp in? I've been thinking about trying one of the Darkglass builds - B3k or Vintage Microtubes - as a preamp but I don't know if they'd need any sort of cab emulation to go with it or if they're both fine on their own. I don't need a ton of drive but like to have just a little touch of grit/breakup (perhaps the VMT is a better choice in that regard). I also thought that running the Equilux post-preamp would perhaps then serve to do any "sculpting" that a cab sim might provide, if needed.

And then direct boxes: Anyone here made their own? I really like the idea of the "Motown" or "Wolfbox" style DI although I know sourcing some of the parts can be a bit pricey. I've also been reading up on an active design, "Bo Hansen" which sounds promising though I've not looked into it too deeply. Anyone have any input on DIY DI's?
 
Di is one of the few things I haven't diy'd and I use 2 (sometimes you need a meatbox only di). I have only recently implemented the equiluxe so I don't have much in depth to say other than it sounds great and I dont feel the need to use my unicab for direct/power amp set ups.
 
The Origin Effects Bass pres are AMAZING and $$$. Had them both, but sold them to fund other things. I play through a Rumble 500 and I believe its DI has a bit of cab sim if I’m not mistaken, and it is post EQ. I do use their Cali76 EQ pedal which is awesome in its own right. And I do have a MB SansAmp board to build- that would work as a decent DI. I’m pretty sure it’s based on one of the older versions.

Long time bass player but just started putting together my bass pedal board within the last year. I’m running a vintage microtubes, a B3k and a Sans Amp mixing in some modulation here and there. I think any of the three pre amp pedals mentioned could be used stand alone just before a D.I. The Sans amp obviously does the D.I. thing as well. They all sound great in there own right but you can also stack them. I’m typically running the vintage microtube and the sans amp on all the time lately, both at low grit/gain. Had a lot of positive comments on my tone. When I really want bring the pain I will flip flop the sans amp off and the b3k on which I have set a lot dirtier. I would build them all again in a heartbeat.

Cannot live without this after hearing the consequences of not having it at a gig:

Friend had borrowed mine (Francis Deck HPF-Pre III) & left it plugged in, killed the battery;
he returned it to me without telling me he'd left it plugged in —
My DB sounded like crap the whole first set, switched out the battery for the second set and at least I couldn't blame the gear anymore...

I can get by with just my FDeck and a Tuner.

'Course, I'd rather have my "fun" pedals onboard, too.


BTW
Francis Deck has made his schematics public, so you can DIY that, but @Passinwind is cooking something up, which I'm looking forward to building.

I would love to grab some of the Origin stuff but I'm on a bit of a shoestring budget at the moment :P
I didn't even think to check at Madbean; had no idea they had a Sansamp (or any bass stuff, for that matter)

Nice! That's kind of what I was leaning towards actually. Was thinking of trying that Maelstrom build from Aion as it sounds like it can be built as a bit of a hybrid between the B3k and VMT? Maybe would be worthwhile to build the two of them separately/dedicated but I don't know for sure; I'm not using a ton of different gain stages typically...
How do you like the Sludgehammer? I haven't played a Sansamp BDDI in YEARS but generally remember liking it.
Are those faceplates from AmplifyFun by chance? Been meaning to give a try.

Okay, tell me more about this guy!
This look like the proper layout? http://tagboardeffects.blogspot.com/2015/01/hpf-technology-hpf-pre-2.html
Guess perhaps I will be doing another Vero after all...

That's v2, which was mainly meant for upright bass. You really want the v3 or preferably the new v4 that will be released "very soon." It will be fully open source, which my new ones will be as well. I'm not at liberty to spill on the new fdeck format, but what he told me about it sounds very cool. Here's the v3 info: https://sites.google.com/site/hpftechllc/home/technical-diy-stuff/hpf-pre-series-3-technical-info

You can see the ongoing design arcs for my stuff in this thread: https://forum.pedalpcb.com/threads/...ybrid-filter-preamp-builds.12146/#post-125511 The standalone variable HPF module will be going live as an OSHpark board share sometime in the next week or two, I mostly just need to settle on a final BOM at this point.

Awesomeness.

Oh heck yeah. I've got that thread on my "watch" now. Very cool.

Hypothetically speaking where would you put that in a chain with some of the aforementioned kit? (Madbean Sludgehammer / Sansamp BDDI, Line 6 M9, Equilux/Equinox EQ, Darkglass B3k)

In my DIY amps I've typically put the HPF last, just in front of the power amp section and after the Aux In. But you can make a good case for any number of other placements too. In the new WTHPF pedal the HPF wanted to go first, which lets the HPF and the bass control interact in a similar fashion to the Equilux/Pultec thing. I'm also working an a bigger format preamp pedal with HPF/bass/one band full parametric EQ/resonant LPF, which will probably have a DI out and a super bomber line driver for use with pro format power amps. The second prototype is currently on my bench but the oncoming cold weather is probably going to slow things down a bunch.

This is the current state of the standalone variable HPF board, which measures 2.0" by 1.08" :

It's a very easy build as far as hand soldering SMT parts goes, and it's small enough to throw in many existing pedals if desired. I've done a couple of fixed frequency builds in 1590A boxes but I may need to reformat the PCB a little bit to allow a variable frequency control in 1590A. FWIW, this design doesn't require a dual pot, unlike any of the others I know of.

Sludgehammer is great. Different flavor from the other two for sure. Different grit, gets fuzzer quicker. A bit more versatile tone controls overall. Still works as my D.I. when bypassed. That said I do prefer the dirt from the b3k or the vintage microtube. More overdrive/grind sound to my ears. If I remember right not to many parts that are different between the b3k & the VMT. You could definitely socket and play around with the values to come up with your own version. I built the b3k first and ordered 2 more boards immediately after finishing it. Built the VMT for myself and another b3k for a friend.

The sledgehammer and tri vibe are indeed faceplates from amplifyfun.
 
So while we’re on the topic (somewhat…), I’m kinda interested in changing up my bass’s electronics.

I’ve got a deluxe active jazz bass. I like it a lot. Good bones, it’s comfy and plays quite nice. Has the “vintage noiseless” pickups, which I guess are okay, but honestly don’t know for sure. Active preamp built in with controls for master, blend, bass, treble, and mids. It’s… inoffensive? I don’t hate it. It’s quiet which is nice but also kind of feel like it lacks for “character”?

So anyways I’ve had two thoughts on the matter.

1. Gut the active portion and install good ol passive electronics. I guess I’d keep the same pickups for now?

2. Put in a different preamp. Anyone have any recommendations? Bonus points if it’s diy-able/PCB exists.

Would you recommend (1), (2), or something else?
 
I've always leaned passive when it comes to both p and j pickups. Those basses are both passive and active on a switch, right? Since it's already set up for it, I'd probably diy a more preferred pre but I do not have any specific suggestions as to what would pair nicely with that set of pickups.

Obviously if you don't like the passive sound, gut that fish.

What is the current control format? And are you in the US or elsewhere?

I've done quite a few Jazz Bass preamps semi-commercially for a luthier friend in Oregon over the last five years and usually have leftover builds and bare boards kicking around. Happy to pass things along at my cost when it makes sense.

Our personal favorite has active bass and mids and a standard issue passive tone control for treble. But I have used three different flavors of active treble control as well, either by way of an add-on module or an all in one three way board. It's not too hard to use a Noll dual pot for both active and passive treble control in one hole too. All this stuff is readily DIY-able and I'm not really looking to sell anything, but for starters the B/M two band board is already on OSHpark as a share and is more or less the same thing used as the front end in those pedals I mentioned.

And yeah, not a thing wrong with just going passive into a pedal (or not) either. I think I'd probably start with a pickup swap and see where that gets you before going down the DIY preamp rabbit hole, personally.
 
I've been thinking about trying one of the Darkglass builds - B3k or Vintage Microtubes - as a preamp but I don't know if they'd need any sort of cab emulation to go with it or if they're both fine on their own.
I use both, sometime in parallel with a mixer/blender, not as preamp but as driver or overdriver and I like them very much, the Tone control isn't as effective as an EQ, you can't really shape the mids, etc. I use them with Aion's TS-50, which is currently pushing the Tech21 VT Bass DI out of my board (I used it as preamp and it's amazing too).


I also use the Meridian (Guyatone PS-20) to shape the sound before going in other effects. Both the Exciter and Color controls are very useful, I would be frustrated without it. Very addictive this one.


I just mentioned it, so I don't want to be annoying, but you can have a look on the Bass Amuser too, there's nothing like a real tube bass overdrive. Darkglass and many other are only trying to emulate that sound with brillant ideas and a touch of modernity. Personal taste but I think it sounds more alive and much warmer than the expensive Darkglass i bought and all the other bass overdrives I built so far.
