Fair enough chap, looks like I'm wrong :-)

However, I still wouldn't do it as the total cab impedance - 8 ohm, wont change if you run it in stereo, so you'll still only get the same power drawn from the head.

Hi Graham, thanks for your reply, I hadn't seen your other one before posting the picture so I hope you don't think I was ignoring it.

Thanks for the advise though, i did think that would be the case but didn't want to try it and have 4 fireballs puffing out of my cabinet haha. I might build a 1x15 cabinet to go with it to utilise the power of the cab. Seems like the most sensible idea!

Thanks again though bud

This is exactly what the back plate on my cab looks like btw so you can see, it just says input above each one

Hey guys

I've got a Hartke LH500 head and Ampeg SVT 410 HE (not HLF) cabinet that I use for but I wanted to know if I was going to blow it doing the following.

On the back of the hartke, it says it only pushes out 250w at 8ohms then the full 500w at 4ohms so I wanted to utilise the full power of the amp. On my Ampeg cab, it has 2 1/4" inputs which i read it says can use used for 2 separate amps (it's a mid 90's USA SVT 410 HE cab btw so it doesn't have speakons) so my question about it is, would I blow the amp or cab if I connected the 2 speaker outs from the Hartke to the 2 amp inputs on the Ampeg cab?

Cheers

I wanted to buy a Q4 or Q5 some time in the future but if the prices rocket like they're bound to, I'll steer clear.
Still, shame the company are bust. Beautiful sounding basses and so well built.

AFAIK, the body on a BB series bass is slightly smaller than the standard Fender P Bass body.

One thing I never understood about the Yamaha BB pickups is why they're a different shape (the lug mounting points mainly) to the standard P style pick up. Is this to stop upgrades?

Yeah they're VSTs and AU files so they'll definitely work with protools

I use the waves GTR3 and get some really brutal tones from it. As well as that, check out LePou plugins. There's an Engl emulator in there which is amazing. Pair that with the cab loader he has on his site called LeCab, choose your cab response you want and it really sounds great. Also, the LePou/LeCab thing is freeware

Agreed! The LH500 is a brilliant, my favourite amp beside the Trace Elliot GP12SMX

Agreed with everyone above, run the VT in front of the Lh500. I have an LH500 as my amp and it is as people say a passive tone control on the mids so it's purely cut BUT the clever thing about the amp is that it doesn't just adjust a specified frequency band on each knob, it compensates each change you make to balance out the frequency curve a bit better.

-that's what the manual says anyway and it does seem that way when you adjust the dials-

BOD2 - I haven't tried using them both together out of the rig as it's a pain removing everything haha. But i might do that. On mine i didn't see the symbol you mean about the double insulation but i don't doubt it's there.

It does have the unbal/balanced switch but that basically just switches between the jack / xlr plugs and i don't have any xlr cables to try it with. The -10/+4dB switch (in out level that you mentioned) just changes the boost, still buzzes in both positions. I've tried it both ways. In the +4dB position, it just amplifies it a bit

Howie - thanks pal, i'll give that a read in a minute

Hi BOD2, yeah I did get it that way as well. I tried each unit on it's own to the hartke amp (left them all in the case powered up too whilst doing this) and it was only the Sony EQ that had the buzzing.

No other units did it, even with all the units still switched on in the rack case, the only one to buzz was the Sony EQ.

Yeah everything was working fine before hand.

As it currently is (and was before I added the EQ in to the rack) the signal chain is:

Bass -> Planet waves 20 foot custom series gold tipped cable -> DBX 1066 compressor -> Aphex Aural Exciter 103C (harmonic boost) -> Hartke LH500 amp -> Ampeg SVT 410 HE cabinet.

All items being powered off of a Samson PB-10 Pro rack power conditioner, all units connected up with normal pedal cables (admittedly they're cheap cables until I can afford to go all XLR but they're what I've always used and they never cause any issues). I use a different cable to connect to my cabinet though, I had it made at a local guitar shop out of really thick cable.

All of the units apart from the Sony EQ have 3 cables in the power lead: blue, brown and yellow/green striped. All these units have been working together for a year without causing any hum or buzzing. As it is now, there isn't any external noise from all of these units unless i stick Sony EQ in to the chain.

Hey guys, it's still buzzing when out of the case I don't know if there's a problem with the unit it's self? It still works fine but there's just that horrible buzzing noise. Problem is, because i use a compressor, it amplifies the hum a bit more when i play.

Hi BigRedX, yeah the unit is a proper purpose built rack EQ, it's a 31 band graphic equaliser. Really good piece of kit.
I'll go and take it out now and see if it still buzzes when out of the rack. If it doesn't, what can I do to prevent it from buzzing in the rack?
Thanks again

Hey Thunderbird and Howiebass, thanks for your replies.

Thunderbird - I would go doing that but I don't want to go mutilating the unit just yet in case there's something else I can do with just the wiring, thanks for the tip though and I will bare it in mind for if all else fails

Howiebass - I've looked on the back of the unit and can't see a symbol like that anywhere? There's certainly nothing around the wiring suggesting it's double insulated either. Also, all the units in my rack are being run off a Samson Pb-10 pro power conditioner which is being run off one wall socket plug. Is there anything else it could be?

Thanks

Hey guys

I've recently put my Sony E100 SRP equaliser back in my bass rig and when I was changing the plug to an IEC to work with my power conditioner, I noticed it didn't have a ground/earth wire, just the brown and blue wires. Obviously, i didn't think anything of it.

anyway, put it in to the rig and it caused some really nasty humming noises to come through the chain. I isolated each unit in the chain and determined it was the equaliser. I checked all the other unit's plugs to see if they all had grounding wires and yeah, they all have the green/yellow banded earth wire. The humming coming from the equaliser was so bad that I've actually removed it completely from the chain again.

So, is it possible to wire in a ground wire to a unit or what can i do to stop it? I'd like to use the unit in my chain but can't go having that much excessive noise coming through the rig. I even tried putting a noise gate after the unit but as soon as you hit a bass note, you can hear the buzz coming through with it.

Oh just as a side not, the EQ was set totally flat at the time too so i eliminated that it was frequency buzz too. I've also read the "humming noises" sticky thread in the repairs section but couldn't really find an answer in there.

Thanks!
Steve

Steve Harris played one of these on one of the mid-era Maiden albums (I believe one or two tracks on Piece of Mind/Somewhere in Time albums. They're great sounding basses, would definitely buy one if I had the money. Nice neck on them too

I had my speaker blow at a gig once and it made my head start to smoke, luckily enough one of my pedals had a DI out on it so I just ran it out of that to the PA for the rest of the show.
In case it was to happen again, I always have some thing I can run in to a PA system with me.

I'll see if i can do that for you in a bit, just need to find my scales

string muters... (i don't have them)



Thanks!

Ah brilliant, thanks for letting me know Every day's a school day an' all...

Personally i think it would be a bad idea to do that, especially if you're going to be hacking in to the CV60 to add a jazz pick up. You may as well just keep the 55-01. If you're that desperate for a 4 string PJ , look in to something like the new Squier VM Precision Bass but I wouldn't get rid of one of those Laklands to do all that to a CV60.

My 2 pennies worth anyway

I don't know the weight of them mate but I use them on my P Bass along with the detuner that goes with them and it's hasn't caused the neck to dive or changed the way the bass feels to play, just made the tuning a lot more stable. Hope this helps you a bit at least?

The fender one is crap! Won't let you mix and match parts.

That sounds really good mate, really punchy tone. Very nice P bass you have there

Sorry, i did make a mistake there. I was meant to say that the number 2 bass was the one that got refinished in black and white checkerboard. This was done so that whilst the main number one bass was being refinished from metallic blue to the West Ham colours, he had his 2nd favourite bass how he wanted it. Only real difference that the number 2 bass has from number one is that it's rosewood boarded instead of the usual maple board.

Again, my apologies for the mistake.
