So the 500ma from the cs7 won't work? Aren't there people in this thread using them?
The CS7 is a fantastic power supply for Le Bass and my other pedals.
It depends on how 'correct' you want to be.
The pedal will work easily on 500mA draw, I ran it for a while on 400mA with no issues whatsoever. If you can get a cable to combine the mAs then you will be laughing which is what I did, it depends how many ports you use.
Make sure you get the correct cable as from my limited electrical knowledge an exact mA is not a bad thing, but the pedal may not work to its full capability, but it won't be damaged, too much voltage and it's fried.

Well close, generally too little voltage and it won't function correctly, too much voltage and it will fry (This isn't always true, as sometimes manufacturers put volatile regulators in so they can handle a wider range of voltages).
Too little current (mA) and it probably won't work and you may damage it (often to be safe manufacturers might over specify here ie say it needs 500 when 400 is probably fine. More current is always fine, pedals will only use as much as they need, on my overkill for a powersupply for example each pedal can pull up to 5000mA on its own.
I changed the tube to a 12AU7 and I really think the lower gain tube meets my needs I am really loving the pedal
I just received my Le Bass and trying to build a board with a TrueTone CS7 powering all the pedals.
Pedals: Le Bass, Dunlop Volume pedal, Polytune 2, MXR bass comp, and MXR bass octave pedal.
The preamp will work on its own.
All of the other pedals will work together alone as well, but they will not work together.
Any Advice?

From my own experience with the CS7, there should be no issue in powering the Le Bass with the 4 other pedals mentioned. In fact, the volume pedal should not even require power so that would leave 3 other 9V pedals to power.
Please describe the issue in further detail, perhaps with pics of both the power and signal connections.
I can take some pictures later on tonight.
When all is hooked up together, the MXR and Polytune flash as if they are having a slow and rhythmic seizure. I am too scared to turn on the A or B preamps of the Le Bass.
They still function perfectly when separated.
I have the Le Bass on the first 12 volt selected channel.
And the rest on the 9 volt selected channels.

It does not stop. It continues to flash and will not turn on.
Again. Once I unplug the Le Bass or the other pedals, everything works like it should. Just not together.
Thank you for your time and input.

You are welcome!
With power off on the CS7 ...
From on top of the board, unplug the power cable to Le Bass (from the CS7), but leave all other pedals connected to the CS7 and to each other.
Now power up the CS7 and all remaining power-connected pedals should be operative from their footswitches.
Now apply the power plug to Le Bass and see if things go into rhythmic seizure. If so, and it does not stop, the issue is with the tube heater circuit in Le Bass.
Please advise how the above goes.
Alright.
Everything worked great until I plugged the Le Bass in. Seizure activity for sure. A few other things of note.
1) The Le Bass works on its own with the CS7, but takes around 10 seconds for the preamp to respond to A or B preamps.
2) tried it at rehearsal tonight by itself. it works on its own with the supplied power supply. It does not behave with any other pedal even my tuner. Way too much noise. The ground switch only helps a bit.
So this pedal is worthless to me as it is.
I guess I need to contact Sweetwater and see what We can do. I bought this for a gig this weekend.
Thanks For the input
Casey
Quite literally, yours sounds like a defective unit.
It should take approximately 3-seconds for the tube warmer in Le Bass to bank enough power from the CS7.
Additionally Le Bass should not be generating the noise with other pedals as you have described.
Sweetwater takes great care of its customers and a replacement unit to you for this weekend's gig is still a possibility.
Cheers!
Well it's been a while since I've posted my Le Bass Preamp experiences here. So I've been using it for almost a year and I've used the preamp in a lot of situations from recording studios to different types of concerts and live feeds to radio stations to Sunday morning church services.
I'll start with the church service situation: Increasingly over the years church sound techs are requesting that they control you via FOH and monitor wedges. Well for the last year I've been bathed in the warmest, round bass being fed back to me in my monitors (both in ears and wedges). I use channel A with the Gain set @ 3:00, Bass set @ 12:00, and the Treb set @ 1:00 (Understand, 12:00 is not 0db on this eq). The goal is to hand over to the sound board the most perfect tone that you can, with the highest amount of gain you can without ever clipping. The Le Bass pedal is perfect for this application as it can provide the deep rich tones and then in the Fusion mode you can add enough dirt or even fuzz if your playing Christian rock.
I've played around with the preamp, and so far not been able to get the A channel to start breaking up. It's just clean and loud.
Engineers from both the radio station and the studio have commented "that the bass tone sounds sweet". I tell them to plug into my Le Bass DI feed and then I turn the speaker emulation on and they love it. In live and radio studio situations if your bass sounds thin or not tight and rich, the Engineer will slip (hide) you in the mix underneath the kick, snare and even put you behind the guitar. I have listened back to concerts, broadcasts and recording mixes and been real happy with the bass sound. And when my band plays some Tina Turner song with those edgy, rock bass lines, I just stomp both channels and play in fusion mode.
I'd buy this thing twice again.

Can someone post the directions to swap the tube?
No idea how to do this without dis assembling the entire pedal.
