    Well, Ive done it - this is now my setup and it just straight up rocks out. I do have a few questions for my fellow TBers. Im fairly new to this mega gear setup so I was wondering if it was normal for the speakers to overdrive when -
    - My gain is half way (or less)and I turn the master volume up (at all)

    - My master is at half way and I turn the gain up (which I figure would drive, but not fart like it kinda does)

    The head is rated 750 watts and the cab is 800.

    I know I will never really need to push the cab more than half the volume on the head, but im just curious as to if this happens to every speaker enclosure when set loud. I understand that most speakers would, but I only had it at half way and there were not any clean sounds (even when I dropped the gain a bit).

    Now, Im not complaining about the sound in any way because it's amazinf, but im curious about the mechanics or reason why the speakers were pushed so soon.
    Thanks guys, Mike

    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.
  3. 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. ; )

    Well, I played through both my fender deluxe v and my stringray 4. Im thinking maybe it's just tube growl, being that this is my first true tube amp that Ive had the ability to crank up. Could something maybe explain the differnece between speaker overdrive and tube growl? It sounded kinda like I had a drive pedal engaged, almost like the RCHP "Around the world" intro. Hmm... if you guys wanna chime in again that would be great. Im also going to give it another test run tomorrow. I should add that by no means will I even need to play that loud (maybe a future outside gig), but I just got the head and wanted to see if everything correctly functioning. I should have also added that I had my carvin 1500 watt amp and a cheap BBE pre to compare and it crank up high pretty clean, until a certain point 3/4's way volume (then speaker overdrive), but that's with 1500 watts not 750. The volume actually did seem to be the same 1500 carvin=750 Aggie (to me at least).
    Thanks again for your help,
  7. 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.

    It actually is clean on my at when set 9:30 on the master. Im talking about when the gain is at 12 and the master is higher than 12. Am my just being ridiculous because I know I wont need that kind of volume (and if so there is always PA support). The first and only time I set it up in a chapel that is fairly large and I was able to pump the volume. This was yesterday and I'm back today with somemore results. I used to different bass (no battery problem), speakon cable, and a monster cable (2 when through my effects chain).
    Thanks again, Mike

    Another question for you guys with this setup - Do you use a compressor and if so which one? Also what are your favorite settings?

    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.

    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. ;)

    Well, after my 2nd test run I have noticed that I am playing really freakin' loud in the chapel. - Oh Yea! Anyways, before I was just putting the gain and the master too high simulataneously. I tried a bunch of different settings this time and this rig just flat out kills. With the gain at 10:00 and the master at 3:00 it was a monster,but still very clean. I am overly satisfied with the tone, but unfortunetly the head weighs as much as the cab. I guess Ill finish by asking another question - The head was clipping (I was cranking it though), but should I be weary and when should I know not to push it too far. I think when Im slapping the string is hitting the pickup causing the clip light to go on. Will I be fine even though the light is blinking at each punch or should I just keep the volume at the highest before the light comes on? This is probably best asked to the people of aguilar, but wanted to hear some of your thoughts.

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

    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... :D

    Keep on rockin', dude! :bassist:

    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.

    I have the top of the line hearo earplugs. I know what your talking about (tinnitus) and I am really sorry to hear that. I actually wasnt wearing the plugs today, but rest assure I will do so in the future.
    Thanks for your share in my enjoyment.

    If you dont get the DB pick up a thunderfunk or a mesa pulse/400+.
    I dont think anything could top my rig (IMO), unless I add another whappo jr. - Any suggestions

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

    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.
