It's not free, but iReal Pro.

Is it aspiration rather than realization - I'm not sure many cab could be literally flat-response? In which case, I could see that two cabs which are "almost flat" could be almost flat in different ways. I would also guess that response changes with volume - I wonder if systems with DSP have some advantage here.

The ground lift switch is for the DI output, not the power. You use it if there is hum caused by a ground loop, which is when two pieces of equipment (a bass amp and a mixing desk) are connected together (with an XLR cable) but each is connected to different grounds. The ground lift will disconnect one of the pins in the XLR, breaking the loop. However, I don't think this is what this post is describing.

Met up in person for a sale, and he was on time and it went smoothly. Thanks!

My 25W lightbulb is so bright because they're Trace Elliot watts.

Which powered speaker is it? Which preamp output (the jack, or the XLR), and which powered speaker input (mic level, line level, or other)? I've used Zoom and EBS preamps (with the 1/4" amp output, not the XLR DI) into an RCF's mic-level input and no problems with volume

The RCF (and most powered speakers I've seen) can't drive a second cab. The XLR output is a link which means it sends a duplicate of the input signal - this is to plug into another powered speaker, not a passive cabinet. But it does mean the internal speakers are getting the full 400W. I think it's 300W to the woofer and 100W to the compression driver. You can't plug two inputs into the RCF (without using an external mixer). For more connectivity options, there is QSC or perhaps a JBL EON (I've not used one myself but it looks ok).

This is a good suggestion. I play upright and bass guitar on the same gig, and I use a powered PA speaker. Its flat response means it is basically a blank slate and you can then do whatever you need to it. For the upright, it gives me a really clear and accurate sound; then I use a preamp and a bit of overdrive for the bass guitar. Better than any actual bass head I've owned. The trick in this case would be keeping in comparable budget of a Hartke KB12/Rumble 500 (so about £500).

I'd consider a Fender Rumble 500 over a KB12 or KB15.

I'd use the DI only to send to the FOH PA system. (It's at mic level btw) I'd use the pedal "amp" output to send to my powered speaker. The pedal output will be in between mic and line levels, so you can use either mic level input with the volume on your powered speaker turned higher, or line level input with the volume on your powered speaker turned lower. I do the first option.

V940FL?

I think the modular approach is a really good one. I use a preamp pedal into various outputs depending on the gig: a powered speaker (RCF 732A), borrowed backline, in-ear monitors, or provided wedges - which means I can get the same familiar "my sound/tone" each time. One thing to consider is that the Harke might impart its own tone. However I've used a borrowed HyDrive 115C combo in the past and I don't love it but I also don't recall it being particularly coloured. I've not used a Samson Servo 300 but another thing to bear in mind is that in bridged mode you'll be at its limits at 300W - i.e. nowhere left to go if it turns out it isn't loud enough, or in the future you want to add a second cab. Crown make some power amps which are popular with bassists: https://www.thomann.de/gb/crown_xls_1002.htm or https://www.thomann.de/gb/crown_xls_1502.htm Also, they have a lower sensitivity setting of 0.775V - see previous poster's comments. Another option perhaps worth mentioning is a powered speaker like a QSC or RCF, which has the advantage of matching the power amp to the speaker, and other DSP options; plus the wedge option, and convenience of a self-contained unit. I find them powerful and with a lot of clarity - I can't see myself ever returning to a traditional bass rig. However, I guess part of the appeal of your potential setup is the deal you are getting on the Hartke.

What is the problem with plugging the Battalion into the EBS? Set the EBS eq as flat/neutral as it goes. Will the Hartke + power amp setup sound any better, louder, or be more convenient, be more scaleable, or save you any money?

This is a 1x8. I really wouldn't think it could keep up with a drummer - I'd love to be proved wrong though (because then I would buy one myself).

FYI there used to be this - http://www.doubletrolley.com/ I never had one, but the impression from reading about it was perhaps that it was neither a great trolley nor a great stool? Hope your project is a success!

There is a house MarkBass CMD 121H - and about three drum kits, a PA, a grand piano. So just walk in with your instrument (through the restaurant - the club is down the stairs at the back). Also, parking really isn't great in Soho so try to avoid doing driving there.

Do you mean an upgrade the audience will notice - i.e. for it to sound better? In which case, subjective, but changing the pickups and/or electronics is a common option. Or an upgrade that perhaps only you will notice - build quality, finish, better tuners, lighter weight, etc?

I saw this one: https://www.thomann.de/gb/rcf_sub_702_as_ii.htm £716, 17.5kg Never used one - no idea if it's any good!

Ah, ok. That's a question more about this GK's two-channel gain feature than the effects loop - and I don't know the answer I'd think though if you're using channel A (and so therefore the level B knob is not in use) you should be able to get a usable output level from the combination Helix and GK.
