Not sure if this will be useful to folks but I thought I would share it. For years I would carry the bass and whatever amp I had and I would rely on the preamp in the amp to help shape my tone. At some stage I think I was using some outboard preamps but basically since moving to mic-only with the XLSON, I've been carrying around this pedalboard.

The first thing to note is that yes it's an extra thing to carry but it's not very heavy or big and I actually put it on the shoulder of my bass as I'm wheeling the bass and carrying the amp or pulling a cart with amp and other stuff in my other hand. So it doesn't slow me down at all in terms of getting to and from gigs. The bag also has a shoulder strap so I could carry it that way too.

What it does allow me to do is to setup and teardown much faster and to get much better sound and have more control over things while I'm playing. Since everything is connected, all I have to do is put the mic on the bass and plug it into the preamp, plug in power for the board (the XLSON preamp has separate power) and plug into whatever amp and FOH and I'm done. Optionally I will also plug into my backup pickup and plug that into the BOSS pedal too which allows me to switch over to it as a fail safe. I then spend time properly dialing in my sound with the parametric EQ and I have to say that, especially with what can sometimes be problematic resonances on double bass, I have a lot more control than I ever did with most amps. Having HPF, LPF, plus the ability to notch out in multiple places or otherwise shape the tone is just fantastic.

Nowadays with the mic I'm just using a commonly-available powered speakers (typically 1 x 8") (although I did just order one of the GR Bass 1x10 active cabs) and at some venues I just make arrangements to use one of their flat-response monitors and I appreciate not always having to bring an amp.

The output from the XLSON is pretty hot already but I have 30 dB of gain on the Empress Bass ParaEQ and typically use some of it. I also have 26 dB of clean gain through the MXR pedal. In theory I can use that for a hands-free boost if I need it as well as being able to turn the knob with my foot if I really need to (not easy to do while standing and playing but not impossible). On certain kinds of gigs occasionally I'm playing stuff where there's simply no opportunity lean down and adjust a knob.

Theoretically I don't really need the Walrus DI as I already send the mic to FOH from the XLSON preamp and I could just connect to the speaker straight from the MXR, however it gives me the option for post-EQ XLR out in case the powered speaker only accepts XLR or for some reason the FOH wants my post-EQ out. I also have a Walrus Stereo DI that I can use instead of this mono one so I can send two post-EQ XLRs if necessary).

I'm super happy with this setup which is why I thought I'd share it. I'm very happy with all the pieces in this. The Empress ParaEQ is just awesome. The MXR is very clean. My failing eyesight loves the huge screen on the Canvas tuner.

Nice! I’m also using a little micro board with only two pieces and like it a lot. Have been wondering if I could fit the Empress on there for the HPF. It’s very tempting.
I have a series 3 HPF-Pre as well as the Broughton HPF (and LPF) and they are all good and the Empress is definitely not an inexpensive thing but it packs so much into it.

Adiran: nice to see you back around here!

Don't be afraid to add a little spice to that board. In addition to the preamp stuff, I always hae an old micro POG for subs and an Earthquaker Spatial Delivery. If I use the spice pedals, I usually bump them on as the note decays, not on the front end. and then hit a bit of boost so they sustain for a while.
 
I've been using the same setup for years now. It either runs into the return on my amp, into a PA, or into whatever backline is available. The DI box parallels to my amp and the FOH when needed. I struggled for a long time finding a setup that would work for the wide variety of gigs I was playing. This gets me in the ballpark with "my tone" 95% of the time. I refuse to give the sound guy a dry signal after some nightmarish results.

Also the little wooden board fits squarely on top of just about any modern class D head so I can fiddle with the knobs more easily. Kind of tough tweaking knobs on the floor while holding the bass.

Since I'm now using the EV Everse 8 as my preamp/amp/monitor/DI, this problem has been ultimately solved by the accompanying EV QuickSmart Mobile app. The iPhone is usually in my pocket anyway, and so I can adjust anything I need via Bluetooth wherever I just happen to be with the bass, even when plugged in with my longest cable which is about 10 m. The app is well thought out, so that everything can be controlled with one hand. The amp has multiple EQ stages and pre-shaping presets incl. a 7-band para-EQ on the master, and yet another 3-band EQ and shaping presets that only affect the power amp output to the speaker. (All features/parameters can be also edited directly on the amp via its small display menu.) Each channel/stage also has a separate mute button.
For me, it's never been so easy to get a good sound. :)

At the last gig earlier this week I've added the Tech 21 QStrip to it as a "pre-preamp" (DB > QStrip > Everse > FOH), but basically flat because I only needed the QStrip's clean parallel output for my multi-track recording setup.

TC Electronic Bodyrez ?
Does it work with DB as well?
Curious to try that with my EUB!

Hey Adrian are those your settings for the mic generally using the Para eq? I have used the Paraeq on someone elses bass with a piezo and with just a bit of twisting of knobs (without really getting detail-y) I found it to be pretty dialed into the bass frequencies in a way that other high quality preamps differ (Felix for example) that is the variations in tone were pretty substantial and ...wide feeling like there was a lot more choice within each area of frequency (if that makes sense) I know this thread kind of opened up into different pedal board setups but Adrians is super specific and dialed....really curious how the Para does with the mic....

One aspect of those settings in the photo is probably not typical as (assuming the dials didn’t get bumped since then) the last usage was a rehearsal last weekend in a horribly live church space with a 16-piece band where we all face each other in some kind of circle.

The HPF and LPF settings and shelf settings are probably pretty typical. Typically for reproduction into the cab I only care about maybe around 60 Hz to around 4 kHz and then I have to deal with one or two problematic resonances somewhere on the A or on the G string. The Q of those can vary a lot depending on the space and the situation. It also depends a bit on how much time I spend dialing it in. Sometimes I also have a mini headphone amp and some ear buds and a small looper pedal with me and if I really want to dial things in (and if it’s noisy around me), I can loop something and then put the bass down and really try to dial things in.

@flatback the one thing I know for sure is that the Para EQ is a lot more useful for dealing with the mic than any graphic EQ is. I had five bands on the last amp I was using before switching over to this setup and it was definitely a compromise when dealing with acoustic issues. Empress makes the best damn stuff. I have their compressor on my EBG board and it's awesome.
 
I was trying to decide between the active 10in GR and the one I bought, the Acoustic cube 12in with the full 2 ch amp. I went with the cube because it is still only 20lb and if I want to do something similar to you the amp has a "Pure" setting on either ch that bypasses the pre (like fx return but without clogging up the fx return) that I can go into. It also leaves open using a mic in the Pure setting (with say a Para eq...which I think needs more props around here for upright... in my little experience with it, it seemed both globally tuned to bass and surgically specific within that) When I had a pedal board I had the Felix on it with a tuner, and I really liked the mute and occasionally boost and a mini looper which I use both for unaccompanied bass pieces and doing what you said above; dialing in your sound without having the bass in your hands...Thanks for taking the plunge with the Xlson (which I thought would work well plugged into a pedal board to minimize the cable run and chance of dislodging it from the bass). The Xlson came Kinda late for me...I was really into doing all that years ago...Im kind of burnt on ever hearing feedback again on a gig. Too many of my own Fups.
 
I actually had the Ischel, which I used as my main pickup for probably about 8 years, feedback more times than I'm ever had the Xlson feedback on me. I know I could never do what I'm doing now with the Xlson with the DPA. Not to mention I actually think the Xlson actually sounds more natural and although I do have to put it on the bass and take it off, it's faster and less fiddly to do that than it was with the DPA.

I just ordered the GR active 10 but don't have it yet. To be honest it was a splurge as I said I was done with expensive bass-specific cabs but the allure of that weight and an active 10" was too much to pass up so I'll be interested to see how it goes with the mic on the upright and whether it's got enough juice to handle EBG for other stuff.
 
Nice @Adrian Cho, thanks for sharing. I am actually building my first pedal board, so I appreciate hearing about yours.

I hadn't been planning on using it for DB. I feel that a side effect of having really clean amps for DB is that my odd BG gigs always benefit from something a little SansAmp-y to give them some color, but I traded my ParaDriver for a Q\Strip which is perfect for DB to a PA, powered speaker or the effects return of whatever, but it doesn't have any kind of a drive.

I recently find myself playing guitar in a new original soul project and decided (since it is unlikely to last) to put together a few BG helpful pedals that would also enhance my guitar daliace for now.

It's looking like:

power supply
tuner
compressor
MXR phase 90 (because funk)
and a drive pedal

I came to the conclusion last night that as good as the Q\Strip is on its own, it probably doesn't make it onto that board. An Empress ParaEQ feels like an investment, but it might justify itself as a replacement for the Q\Strip at some point for the variable HPF.

Then it could become a tiny pre-amp board for DB too. I am on-board with the future of small, light DB amplication not involving a pre-amp stage on the amplifier.

I'm glad my post was helpful. Yeah underneath my board I have a Caline CP-205 power supply which can provide 7 x 300 mA + 1 x 500 mA at 9V which is way, way more than this little pedalboard needs. I could instead just run it all off a single 9V supply and share the plugs but each one having it's own isolated supply is better.

In case it's interesting I thought I'd share my updated pedalboard setups. The bigger board is a slight tweak on the one in the original post. I have a looper and a DI on this one plus everything is completely plugged in. The XLSON mic is already sitting in the mount and it is protected during transport inside a mic windscreen. All I have to do is plug in power, put the mic on the bass, and plug the FoH into the XLSON preamp and, optionally, also into the DI. FoH gets the raw output from the XLSON premp (top-right) and top-left, which goes into the on-stage speaker and as a second channel to FoH (mostly as a backup) is either the mic after all the EQing, or it's my pickup, depending on what I want to do.

The smaller board is just for pickup only gigs. I could also potentially put a phantom power supply on here and go back to using my Ischel as a backup instead of the bridge-mounted piezo. These are basically cases where I just know, for whatever reason I am not even going to bother with the mic. Sometimes it's a very quiet gig and I can get away mostly with the acoustic sound of the bass, it's an insanely stupidly loud with no FoH.

With both these boards I really find it useful to just have everything plugged in and ready to go. Just saves time setting up and tearing down. The little powerbars have USB outputs too so I can charge my phone or something else if I need to.

On both these boards I'm not using isolated power supplies for each device now. Everything works fine just sharing a single plug from a 1A 9V adapter. On my much bigger EBG board I'm using dedicated supplies because it's so much more complicated and there's a lot more current being drawn.
