Quilter Bass Block

I received my Bassdock 12 last week. I had the opportunity to use it at 2 outdoor gigs. Great tone, much rounder than my Bassliners. I usually use the the 2x10 Bassliner C with the 2x 10 wedge on top. The new Bassdock 12 held it's own with drummer, and 3 guitarists in a blues band one day, and a classic rock band the next day.

Awesome! After doing a comparison with my rumble 210s I may order a second for a little stack.
 
After my gig on Saturday night, one of my bandmates was helping me load out and dropped my BB800. Although it was in its carry bag, when I tested it on Sunday I found the master volume pot was destroyed. I live in New Zealand, so sending it to the US would be a pain, so I emailed Quilter and Pat himself emailed me back in less than two hours, saying they would send a replacement pot out on Monday morning. That is outstanding service, and there's a bunch of other major companies in this industry who could do with reminding about customer service. Pat Quilter, you are the MAN, and I am so glad I came back to Quilter.
 
Experimented with this at home yesterday. Very punchy and articulate.

Hi, all.

I just picked up a Bass Block from the classifieds. It makes a "pop" through the speaker (not loud, but not faint -- has some high frequency content and goes through tweeter and woofer both) on power-up. Pop is the same volume regardless of Master volume position (happens when the volume is dialed down to zero) and comes through the Line Out (though it sounds different -- less treble) as well as the cab.

The pop is more than the low, quiet "woomp" some amps make when they come on but, to be clear, much less than the potentially dangerous (to rig and PA) pop you get when someone ill-advisedly plugs/unplugs their instrument while the cable is connected to the amp.

It's a little annoying, but does not, I think, present any danger to the cab or PA -- I usually power-up the amp with the volume at zero, but, even if I didn't, the pop does not get louder with turning up. The pop through the line out is at a pretty low level, too (I checked this by plugging into a power amp and slowly turning it up with successive tries).

There is one more, weird, little thing that I noticed accidentally when trying the Bass Block with different cabs (with a Speakon cable): if you turn the amp off and then plug into a new cab (while it's off), you'll get a faint (quieter than the other pops), high-pitched click through the cab. I'm thinking this is some sort of capacitive discharge -- it will continue to do this for a few minutes after being turned off. After that, no.

So, I'm wondering 1) Is this normal for the amp? and 2) Is any of this indicative of some other problem or potential problem with the amp?

The pops themselves are a "meh" -- not enough to be dangerous nor, I think, to annoy the person running sound in any significant way (and the previous owner reported positive feedback from sound-folks re. the line out).

I might be worrying more than I need to because I had one of these in 2016, shortly after they came out -- that one had major issues out of the box and had to go back, but I was intrigued enough by what I heard that it was always in the back of my mind to try one again. For what it's worth, this amp was new from the factory in 2018.

So, there you go. Any insight is appreciated.

Mine def does this as well....also last week the mute button was also making a popping sound...did it like 12 times in a row regardless if bass was plugged in...I could see it moving the speaker a decent amount...unplugged it and plugged back in later and could not make it do it again...makes me nervous as it's all i have for a bass head right now..never been the biggest fan of the preamp section...power section is good though

If it's enough to "move the speaker a decent amount" that would concern me. I don't think that the mute button on this one is doing that. The mute button on the old one did, but I don't think it was moving the speaker visibly (which would imply some low-frequency content at a good level), just a high-frequency click-type sound.

I would write Quilter if I were you and see what they say. I might also turn the volume down before hitting mute, to be safe (if that affects the volume of the pop coming through your speakers -- if you can get it to happen again).

I will check mine again -- pretty sure the mute switch is quiet on mine. The other pops on mine are independent of the Master Volume on the amp. Pretty sure they aren't moving the woofer any significant amount, which would be concerning.

Again, I'd like to know if this is typical behavior for this amp -- i.e. slightly annoying but nothing to worry about -- or if it's indicative of a possible problem down the road.

All you happy Quilter owners out there, do your amps do this?
 
I get the slight pop for on off independent of volume. Honestly I never paid any attention to it until you mentioned it here. I am used to amps doing this. I am sure some do not, but most of the ones I own/have owned do/did.

Mute switch is silent. That said, I would love to see Quilter treat the mute switch more like the speaker on/off on my old SWR head (dedicated switch that stays on/off until you switch it again instead of a soft switch that is reset with power cycle).

That's interesting -- I think that most of the ones I have do not -- or do it in a different way (very low "woomp" vs. a "pop" if that makes sense) and/or to a lesser extent. (I'll be paying attention for the next few days, whenever I power up an amp!) At any rate, it stood out to me when I first powered it up -- not like Yow!, but like Hunh.

There's also the little pop when plugging the speaker cable in within a few minutes of using the amp (not that you'd do that often) and the fact that the "power-on pop" comes through the Line Out...

While I find these little clicks and pops slightly annoying, I'm not so much concerned with them, per se, as worried that they might be indicative of a possible something more serious, however unlikely -- a static discharge that fries some delicate components or sends an unsafe pop through cab and/or PA...

Yeah, I could see that. I think that the mute switch on the Kustom KXB500 operates in the same way as the Bass Block.

Mute switch on this one is quiet, I think. Old one clicked. @golfnsubie's, though -- if the mute switch is causing a pop significant enough to cause visible woofer movement, that's a cause for concern.

Yeah I was playing through my MAS 1,8 which does has move speaker movement than many cabs but regardless...I hit the button quite a few times and it did it everytime regardless of my bass cable being plugged in....funny thing is it hasnt done it since then and it's been played 8+ hours...took my khs mute pedal with me this weekend as I was playing a pretty big venue with a expensive line array setup and plenty of subs, I wasn't gonna be the guy with the pops lol

Mute functionality might be part of this. The SWR heads I have used never pop in use, but I also turn speakers off before power down on those. Betting they would pop a little if I did not switch speakers off before power of and speakers on after power on. When I say I am used to amps doing this, it seems like most of the combo amps I have owned over the years have done it, but again no dedicated mute/speaker off on those.

Moral of the story... I am using this post to once again complain about how the mute switch works on the BB800. Not a huge deal, but I do miss a dedicated switch that does not reset with power cycle when I use the BB800.

Still, it shouldn't be acting like that -- that it doesn't at least some of the time would seem to corroborate this.

Could it be due to some oxidation/crud on the switch (like you can get in a volume or tone pot)? I wonder about the reliability of that little momentary switch (though it might be very reliable for all I know).

Does the pop come through the line out, too?
