Quilter Bass Block v803

Based upon what you've told us, the first thing I would recommend is a variable high-pass filter. I won't gig without one. :)
Someone somewhere in this thread indicated that the 803 has a fixed HPF at around 30 hz, as do many amps. I've never seen good documentation though I've looked. The variable piece is what Dogg is highlighting. …cool indeed! There are many options to consider.

Hey, thank you all! A warm welcome is always appreciated 🫶

I was going to quote each one into my reply, but I'm on my phone and it was taking me a long time😬😑.

I have used the rumble in some situations with around 100 people with no PA, yes, but it were more of 'background music' gigs (weddings, mostly). Currently, most of the gigs I play are with a 4 piece band of blues. The drummer is not very heavy handed, and the guitarists are mostly conscious about their volumes, so it is not that I'm drowning in my bandmates sound.

But I hear you all, and I'm glad to confirm it should work great (as mikeynets said, that extra power should be a very nice headroom to have). I'm going to give it a little more thought, to be sure it is not mindless GAS (I mean... I know it is GAS, but I have the cash, and I really think it is a good improvement after more than 10 years with the Rumble. And also GAS).


Also, thanks for clarifying setups based on cab Ohms. 8 ohm sounds like the way to go... GR is very appealing because of the weight. I've looked the Barefaceds, but seems like I would have to import them from the UK (I'm in Spain, sorry, I didn't mention it before) and it would be more hassle than getting a GR... But I'll keep looking.

Any other light, compact, great cab you guys can recommend?

Another really good option for speaker cab(s) is Genzler - either their Ultra Light series or the Bass Array series, not cheap, but worth the coin if you have it.

@Jeff Genzler is active on these forums and can help you find the best way to get a hold of them from Spain.

I have no affiliation with Genzler, but I used to own a couple of Genz Benz products (later bought out by another company and then shutdown) - excellent products and customer support!

Hello there! This is my first post in TB, so please be gentle 😂


I usually play in blues, soul and funk bands (although I like stoner rock as well, but I'm not currently playing in any stoner band). I have a Fender Rumble 100, which I like, although I find it a little bit boom, and the bass is not as defined as I would like (but it is a great amp nonetheless). I'm starting to think about an upgrade and I'm liking very much the feature set of the 803. I have some money now, so I would like to upgrade to something that will stays with me for a long time.

But the problem is that I'm afraid the 803 can be a bit overkill for my use case... Most of the gigs I play are around 60-100 people and the Rumble gives the needed sound pressure, so the Quilter master would be set very low. I've seen some people in this thread using it at low volumes and the comments are positive, but I thought it wouldn't hurt asking it: what do you think? would it be overkill?. It is more watts than I would need most of the time but I don't find any other cabs that are that appealing in terms of sonic diversity...
Also, cabs:

If I end getting it, I was thinking about getting a GR bass cab. The idea of having a killer rig that weighs even less than the rumble is VERY sexy. Thoughts about using the Quilter with a 2x8 or a 1x10? And regarding impedance, I was thinking going 8 ohm, to address somewhat the ridiculous amount of power of the Quilter, but I've seen some people in here using 4 Ohm cabs (although I think they were using bigger cabs, 2x12, 2x10, etc). Am I correct that 8 ohm would be the route to go or 4 ohm is perfectly fine?
That's all, I apologize for the long post😅. I hope it wasn't a wall of text, I don't have many bass friends around, and there's no store around me that has Quilter or GR.

Thanks!
Last week I had a ~100 people blues gig. With the v803, Barefaced BB3 and GreenBoy F112. The master on the Quilter in Qtube mode was a bit less than noon and the peak led of Gain wasn't shining, that means a lot more volume available.
It was a very enjoyable gig. I could play veeeery soft as hearing people conversation, and I could dig in the strings to feel the low freqs on my chest.

I have tried the v803 with a GR AT112H. The sound is good (and the weight is better) but at high volume I prefer my cabs.

I haven't tried GR 2x8 or 1x10, but I would not go for it, I think it would lack low freqs and would sound compressed.

Hey Diego! Thanks for your input. The BB3 seems like a bit overkill for my situation, but I've been eyeing the SuperCompact and the SuperMini and I'm leaning more towards them now.

When you say that at high volume you prefer the BB3, you mean outdoors gig volume?. How did the GR compare at lower volumes? (small pub gigs)

I ditched the idea of getting a 2x8. I would love the portability, but I need something than can work at bigger venues. And 1x10...I'm very curious about the BF One10, but I don't think it would make a good pairing with the 803.

I have the Barefaced One10 and Super Compact. Both excellent in their own way, and both pair well with the Quilter v803.
  • Tonewise, the One10 sounds warm while the Super Compact is more neutral. I like both, but they're quite different. I think the video demos you can find on the Barefaced Youtube channel give a good sense of this tonal difference (I've ordered both without the possibility to try them, just after listening to these demos, and they both sounded excactly like I expected, only better).
  • The One10 is surprisingly loud for its size (and weight), it's good enough for rehearsals and small gigs. The only occasion when it struggled was during an outdoor gig, I heard it was suffuring so I had to cut the lows on my amp's EQ and dial in more mids. The Super Compact is significantly louder, and it can produce massive low end without suffuring.

When using the Quilter with the one10, where do you set the master volume? Is it too low?

Also, did you try using both the One10 and the supercompact together?

The One10 is very attractive, but I think I would be missing some pressure on the bigger gigs

Just bellow 12 o'clock

No, because the Super Compact can be louder than I would ever need, and I have no car, so I always use the public transports to go to my gigs.

Maybe the Super Mini then?

I have a couple 4 ohm Revsound cabs rated for 650 watts (RS210) and 350 watts (RS28). I hear that the master volume on the Bass blocks act as a sort of watt limiter? Would it be safe to use a bass block with these cabs as long is the master stays below a given range? Is there some sort of guide where you can know that X position on the master volume = X number of watts?

EDIT: just looked closer at a pic and i see that hte master volume literally shows watts. haha. I guess I'll leave this question up anyways, as this concept is new to me and I don't want to risk destroying anything.

I think that under the hood it works like any master knob, Quilter just decided to change the labelling on the 800 in order to give a rough estimation of the power produced with a given setting.

The 803 probably works the same way, so using the master knob at 2 o'clock (equivalent of 400W) in order to keep a safety margin for your 650W cab, you should be fine. But it also depends on the EQ, I suppose that if you have a lot of bass in the EQ you can damage the cab even with this "400W equivalent". 2 o'clock with a flat EQ (or at least no boosted bass) should be fine, that's what I would do.

The Warm and Qtube settings @ 4 ohms only go to 500W per the manual. You should be fine with the RS210, and with caution with the RS28. But as always, listen for complaints from you cabs.

How are users liking how the cab sim and pre-post eq settings behave on the XLR out relative to the amp voicing that is selected? If my research is correct, the "modern" response setting has no cab sim and the XLR is "pre" EQ, but with the other "warm" and "tube" setting it's post-eq with a cab sim applied. Does this work well for people in practice? There's a little voice in the back of my head that suspects my ideal arrangement for gigging might be "modern" with a cab sim applied, but I guess there's no way to know without trying it.

I like the cab sim when using the warm and qtube voices. I send the XLR signal to a board to get the band mix back in IEM's. I'm not sure how to describe the effect but it's rolling off some highs and smoothing the sound overall. Sounds great in a busy mix. Run it clean or push it for grunt and grind.
 
How would people describe the voicing of the "modern" setting? Is it totally flat? I'm wondering if there is any way to compare it against other transparent leaning amps, like Markbass, Genz Benz Shuttles, Bergantino, Trickfish, etc.

I have a Shuttle 3.0 and 6.0 that I use with different cabs for different applications, but I'm wondering if the Qulter could replace the transparent sound of the 6.0, plus give me a couple additional voicing options.
