Aguilar 750 and AccuGroove Whappo Jr.

I had the exact same rig. I never managed to get the speakers to fart at all, but I never had my gain past 10 o'clock. The volume of that rig kept both master and gain at around 9 and 10 o'clock. I did crank my gain this last week when I used my B2, and the worst I got was a little tube growl.

 

If you're barely turning up the volume and your gain is only half way at most, the cab shouldn't be overdriving like that.

Sounds like you need to examine everything and make sure it's all kosher.

 

That doesn't sound right. Are you sure it's the speakers overdriving? I've turned my El Whappo way up and there's no distortion, it's way loud and clean. Maybe the gain on the amp is too high? Otherwise somethings at fault here.

 

I have the exact same rig and use it at least weekly at gigs.

There is no way in heck your speakers should be "overdriving" with the gain set about halfway and the master volume up some. Of course, I don't believe you mentioned what bass you're using, whether your input is set for active or passive, how high you have your bass volume turned up, etc. However, as a rule, this is something that would be unusual.

You should note I just played a gig in an extremely large room with no PA support. The gain was halfway and the master volume might have been at 9:30. And I was LOUD.

Also, you didn't mention which way the AccuSwitch was set. ; )

 

It certainly seems like something is amiss. As with Kjones, if I run the DB750 gain at 12:00 or slightly less and the master at 9:30 through my EL Whappo it is LOUD... enough for mid-sized clubs with no PA support. The DB750 has massive power and headroom, and the Jr. should have no problems.

You prolly know this, but something to be clear on... the DB750 is a hybrid. All of the tubes are in the front end (preamp section) and are affected by your input gain setting. The power section is SS.

At this point I would start looking at the obvious. Are the batteries in your bass okay (if you need them)? Have you tried another bass cable? Are you using a proper (hopefully speakon) speaker cable and is it wired correctly? Is the distortion you're hearing caused by vibrating walls or ventilation? Failing that, unless you purchased the amp new, it's possible that someone played around with the tubes.

 

Well,

If you have your gain AND master at 12:00, with the jr. that sucker should be insanely LOUD.

I had a 750, and used it with various accugrooves, and because the thing has so much headroom, I was always able to get a very clean yet loud sound. Of course if you overdrive the front end, then you can get some tube grit out of it as well.

From where I'm standing, if that rig isn't incredibly loud yet clean with the gain at 10:00-11:00 and the master at 9:00-10:00, somethings off.

I hope you sort it out, thats a great rig!!! I should never have sold my 750, I will regret doing that forever.

 

How are your EQ knobs set?

 

It's been awhile since I've logged onto TB, saw this thread, so I'll toss my 2 cents into the pot...

I have a DB750... luv it... and I have two different cab choices: a Bergantino NV215, and an Eden D410XLT... both cabs are 4 Ohm. Depending on the gig pretty much dictates cab choice; however, I tend to use the 410 more often. Once in awhile I get to use BOTH cabinets, and that pushes the DB750 at 2 Ohms... oh what a feeling! ...and the overall sound is amazing!

I usually set my Master at 7 o'clock, then I'll crank the Gain up to 1 - 2 o'clock. I'm purposefully looking for that over-driven tube sound, which this amp most definitely can replicate very well. We play mostly 60's & 70's rock classics, so that's the bass sound I prefer. I also have a Marshall VBA400, and I find I can get the DB750 to sound almost just like my beloved all-tuber, but at a lower volume!

Anyway... I know I wasn't talking Accugrooves here, but my cab choices easily handle the power of the Aggie... standing alone, or paired together.

 

First of all... you're crazy, brah! However, 'dey be your ears, so, like we say out here in 'da islands: geev'um, braddah!

It's always a good idea not to do any clipping, so I might suggest you keep to your own thought: "...just keep the volume at the highest before the light comes on...", or just before you see blood start dripping out of your earholes...

Keep on rockin', dude!

 

I'm glad you've found your sweet spot. Now, like the old fart I am, I am going to give you some unsolicited advice. If you're playing at that volume, please go get a set of appropriate earplugs, preferably made for you by an audiologist. No one gave me that advice when I started playing many years ago, and now I have tinnitis (ringing in the ears) all the time. If you can't hear, you can't play bass. Now that you've got great equipment, keep the most important equipment protected so you can be rocking out when you're fifty.

End of sermon. Enjoy your fine stuff.

 

Hmmmmm.......I need to find me a DB750 (Euro Voltage)

Just completing the purchase of an El Whappo and all this DB750 talk has me gassin

Oz

 

a 750 and two whappo jr's would be simply awesome

You'd probably never clip your amp with that setup as well!



as for "topping" your rig, how bout a 680/728 with a pair of jr's???

 

Frankly, Funky, I don't think you need another Jr., if you need that much sound, you probably should be going through the FOH.

What I added was an Accugroove Tri 112. What that does is allow me to have something very light that sounds great (same kind of transparent tone) that's even more easily portable, and perfectly useful for smaller gigs. The 210 would be in that same vein, although it's a lot heavier than the 112. And, if you have some, for example, outdoor gig, you could certainly use them all together.

 

I told you it was the sound of god...
