I've never measured to be honest, alter the bass side and the whole pickup level until you are happy that it has a good output on the E with a good full sound not being choked by the magnetic force or the pickup stopping the string vibrating, then adjust the treble side until you get a good even output across the whole bass, do all that with a flat tone if you can, if in a band mix you feel the D and G are getting lost raise that end a bit at a time until it is sweet, I keep a suitable driver to hand at the following practice after any pickup fiddling

Funny old world eh?

Thats not music though, it's research material for his book..........

[quote name='BassBunny' timestamp='1423927652' post='2690463'] I think if you check further you will find the 3110 is already running at 4 Ohms, and thus the maximum 300W. The internal speaker has two 8 ohm voice coils wired in parallel thus you have the full 300 watts with the internal speaker. When you plug in the external speaker one of the 8 ohm windings is disconnected. So although an additional speaker will move more air, you already have the full 300W as the combo stands. Here's the info from the user manual.

You can connect the TC 210 cab to this combo and it will work just fine. It'll sound much louder because it has more speakers making more sound and IMO that will give it a better tone. Nothing will break or sound bad because you have caused a problem by adding the extra cab. Take your combo and bass to try it with the 210 cab, so you can check you like the sound, before you buy. You can also try other cabs as long as they are 8 ohms. Ask about another 210 cab later, if you find out your 310 rig doesn't do what you want. [/quote] That's fine not understanding all the other posts but as you can see from the picture BassBunny found it is showing a 150 8 ohm cab to pair it with, of course they want you to purchase that but at the same time you would be able to hear both matching drivers starting to fart with their recommened setup, you wont hear that 150w 1x10 dying with a TC 2x10 400 watt cab in it's stride. The maths mean nothing really so I'll ask you this, the amp will put 300 watts max into the internal driver or 150 watts into each 8 ohm load (half of the internal driver plus extra cab) so the maths say it can cope? Now run the amp on maximum with some 5 string bass through it, do you think the internal driver would cope or like every other combo on the planet things would start to get messy with the single driver?

Lots of presuming there though isn't there? If we are presuming then I'm presuming the 150 watt voice coil will get ruined by the possible maximum wattage going through it? Unlike a regular amp all you can do is send half the original power to an eternal driver, it's more like cutting a 2x10 cab in half than actually adding a cab, so adding a 2x10 is like having an 8 ohm 150 watt max 1x10 and 400 watt 2x10 in parallel, would we normally advise that as a good setup?I'd say no?

That is all well and good saying it has "gone into information overload" but the internal speaker will be rated at only 150 watts max with the 2x10 added, "add any 8 ohm cab" is great advice unless it hides the combo driver crapping out with 300 watts going through it that a 400 watt or more ext cab will happily handle? This is not like any other combo where the 300 watt rating of it's driver remains constant is it?

Ha, I dont go on there, my 2007 fretless has a 2004 fretted neck and my classic5 has a john east preamp, my 2010 is stock other than straplocks whichvthey probably dislike too, lol

[quote name='taunton-hobbit' timestamp='1423943276' post='2690751'] If it says minimum, it means it won't like 2 ohms a lot (burning smell) - I'd talk to Ashdown, but I think, like many, you are trying to get out of a situation at the minimum cost - nothing wrong with that, but 'yer gets wot yer pays for' at the end of the day............... [/quote] [quote name='taunton-hobbit' timestamp='1423949611' post='2690868'] I preferred my answer, but then I'm old & frail (shuffles off for Ovaltine laced with bootleg Vodka). [/quote] Well it was a good reply but just as flawed as my earlier TC advice as it's not an Ashdown, lol

That will be Ceramic then, I like my Ceramic one but some people prefer the Alnico for that classic Ray tone, interestingly some people find the output too hot to handle on the ceramic basses and just too in your face, I wonder if there is an issue with it? Also and this is a biggy, the ceramic one on its own can sound a bit odd but in a live band mix it is crazy good, series with the mids boosted and basically you are going to be heard in any band mix! I love my 2 eq Alnico equipped Classic5 but it can be more difficult to get to cut through a pair of Les Pauls at full belt

Dont worry about those switches they are for when it's plugged into a pa via the DI built in.

Adding the extra cab should give you more air being moved but no more power unlike most combos with an extra cab due to that clever switching inside, adding any cabs is always an unknown area tone wise, adding a matching cab with 8 ohms is the normal advice but even that is not so easy as they wont actually be matching drivers as your combo one will be running at half capacity if that makes sense? Take your combo to a good bass amp shop like bass direct or bass gear and they will let you try your combo with other cabs and try some other amps and cabs to see what you like, two RS2x10s and a TC head maybe but you can see why many of us run a 1x12 combo or head and cab with a second identical one for bigger gigs, I've actually got a 1x12 and a 2x12 as I bought the 2x12 first.

Is it ceramic or Alnico, tbh honest I tried a TM5 in PMT when I was Jazz shopping and found it like a Stingray with a flat battery and a weak pickup

Good point, lowering the pickup away from the strings can actually work better if its previously been set near the higher action strings.

[quote name='3below' timestamp='1423946243' post='2690806'] If you want more SPL (volume) then another way forward would be a more efficient extension cab - e.g. Barefaced compact or similar. Not all cabs (speaker + box) are created equal, some deliver greater SPL per input Watt than others. Treat most manufacturer figures with caution. [/quote] I think the problem here is (and I've answered my own question above) is that you are quite correct that the extension cab would be great......until the next time you plug the combo in on its own to find the internal speaker no longer...well...speaks?! The nice sounding barefaced would mask all the power destroying the single 8 ohm speaker in the combo?

Loads in parallel get divided between the number of loads, the load being in ohms two 8 ohm cabs equals 4 ohms two 16 ohm cabs would be 8 ohms Four 16 ohm cabs would be 4 ohms a single 4 ohm cab is just that same as 8 or 16 ohms all would be above the 4 ohms minimum required by most non valve amps most of us have. Loads in series adds the total so two 8 ohm cabs equals 16 ohms two 16 ohm cabs would be 32 ohms four 16 ohm cabs would be 64 ohms To do that you need a special series lead, why would you you ask? Well you could pair two 4 ohm 2x12 cabs in series to give 8 ohms then do the same again and put both pairs into the head in parallel giving 8x12 speakers and the 4 ohm load the wants to produce its full power! Your amp has the two 8 ohm loads pre wired in parallel inside tricking the amp into thinking you have already added an extra speaker cab, when you plug into it one gets disconnected (probably by the jack socket pushing a contact open) so if you plug a lead in it will see 8 ohms then let you add another 8 ohm load giving the amp a 4 ohm load as before but with more drivers pushing more air. To complicate it more you could put two 2x10 8 ohm cabs with a series lead between them and plug into the head from the first one and have the combo driver and both 2x10s running at a total of 4 ohms (does anyone else agree?)

To be fair Saxy your amp is quite unusual having the ability to be working as 4 ohms on its own and still 4 ohm when you add an extra 8 ohm cab, clever but not so easy to describe.

Where is it buzzing, behind where you are playing or choking nearer the body end?

I like to get the neck as flat as possible with the bass tuned up then just let a smidge of relief in so if you hold down the 1st fret and 13th fret you can just about get the string to ring out when tapped in the middle (thumb on 13th and 1st finger to tap), once that is set you cant do anything else and most ebmm basses already have a shim in the neck pocket, adjust the saddles to what you want, I use an allen key (2mm I think) under the 12th fret wire and the back of each string across the board, tune and intonate until it rings like a bell My 2010 SR5 has a slightly high fret that needs a tiny dressing if anyone wanted it super low but its fine for me and if it rsttles I know its time to adjust the truss for the seasonal change, I see people suggesting people altering the saddle heights to restore basses back to normal but once you have it nailed all you EVER need to do is turn the wheel of fortune to make it play and intonate perfectly, brilliant.

Most combos run 4 ohms min load and an 8 ohm built in speaker (unlike the unusual one the OP has), so you can add another 8 ohm cab underneath to get a 4 ohm load (2 8s divided by 2 cabs equals 4) that will give you the full 180 watts the amp can produce hence you get more power and more driver area, double whammy upgrade! If the head can be unplugged from the combo cab you could run any combination of cabs as long as they combine to a total of at least 4 ohms (4 x 16 ohm 2x10 cabs all wired in parallel, 2 x 8 ohm 4x10 cabs, a single high quality 4 ohm 2x12, etc etc

Welcome and enjoy, mine is just the standard in violin burst so I'll bet the deluxe rocks! Or should that be Jazzes? Lol Pics when it arrives please.

Well there is only one thing better than a Bergatino cab....more Bergatino cabs!

I have confused you more thinking this was a TC product rather than Ibanez! ignor everything I said, Lol.

What I meant is they only advise it with their own cabs as they can't vouch for other brands being 8 ohms can they? I like combos that have a removeable head, 1x12 combo at the dog and partridge one night then running a pair of 4x10s at the megadome gig the next night

How brilliant is the EBMM wheel of fortune truss adjuster?!
