Mr. Foxen

That the orange one? Bassist from Geisha uses one that he describes as 'the dog's kicked in bollocks'. I had one, made me do widdly shred bass, from the definition, moved it on.

[quote name='KingBollock' post='1332532' date='Aug 8 2011, 06:41 PM']Not as rare as they should be. Unless you count landfill sites...[/quote] They are great if you don't break them.

Also, really not very rare.

[quote name='KingBollock' post='1332326' date='Aug 8 2011, 04:24 PM']Could this kind of thing cause all the capacitors inside to lose their innards? I had a Laney Klipp when I was a kid and I used to wire all sorts of different speakers to it, in all kinds of configurations, without knowing anything about impedance or valves, in fact I still know bugger all about valves... I just know that one day I saw the magic blue smoke coming out and when I opened it up (I used to open everything electronic up when I could) all the capacitors had popped open.[/quote] Don't still have it somewhere do you? Those caps are easy to replace, an I have a big bag of them I just ordered. I don't know if impedance fun can blow the filter caps, usually it is valves an resistors that go other than the tranny itself. They did use pretty cheap caps I think, a ton of smaller ones instead of big cans.

[quote name='neepheid' post='1332309' date='Aug 8 2011, 04:15 PM']I don't know what that means, other than I'm guessing it's a bad thing and to expect fireworks/loss of magic smoke soon?[/quote] If you have a valve amp on with no speaker attached, all sorts of bad things can happen, as the equilibrium of the circuit is reliant on the output transformer having a load on it (completing the circuit of its secondary winding). Having a speaker and the impedance selector is wrong but not fatal, having no load at all can really mess things up, like the amp goes into oscillation and totally cooks itself.

Anyone hit the report button? Sure it helps any claim after the sale.

Number them and pull them, putting back in the same place makes no odds. When was it last biased and how old were the valves when it was done? Bias will ahve moved a bit anyway if they were new since they wore in.

not quite sure what you mean by that. But basically, you have a cabinet that isn't doing what you require of it. Changing speakers will not help. You need a better cabinet, or more of the same, if you want that sound, but louder.

Looks kind of like it could be a casting flaw that has cracked the metal. They gradually crystallise over many years an go ping eventually.

[quote name='SidVicious1978' post='1331583' date='Aug 8 2011, 12:38 AM']cheers so if i changed the speaker to 200w would that still happen[/quote] You'd have a 200w speaker in it, that's all. The watt rating is nothing to do with when the speaker breaks up, it is just the point where the voice coil melts or fails. Chances are the speaker would also be different in a bunch of other ways, likely ones that would make it fart at lower volumes as it wouldn't be as suited to the cab.

That would probably be the speakers hitting their excursion limit. Means you need more of them, or to back off the bass on your amp. And shut off the ashdown sub octave.

Or oil finish it yourself. Good clean up and wipe on Rustins danish oil (with all the hardware off) an you are good to go. Few days work and drying. Easy to patch up. Oil finishing really isn't a pro luthier job.

Two 16 ohm speakers in parallel makes 8ohm, so that is fine. Crackling rather than farting sounds like a loose connection, so check that first. The watt rating is nothing to do with bad noises from speakers though. If you find they are melting, then you want to look at that rating.

For all the odds it makes, might as well tippex out the 2 and replace with a 4. The RMS wattage is not a useful sort of number to base cab performance on. 400w drivers might fart out earlier than the ones in there, and be quieter.

RMS rating doesn't tell you anything useful anyway, so not much point in knowing it. If you are wondering what sort of power head to use, the answer is any, they all have a volume control somewhere along the kine. Listen for the cab farting out, if it does, back off the volume, if that isn't loud enough, you need more cabs.

Ampeg distributor.

Volume knob sorts the level jump, if has a big range as it has the juice to go direct to a power amp. The high knob is boost only, although the character simulation of the pedal includes a speaker sim with the treble roll off built in (switchable on later ones). So bear that in mind.

Does look a lot like a 70s catalogue bass.

[quote name='Grant' post='1329592' date='Aug 6 2011, 08:49 AM']Thanks for your explanations guys - very helpful. Judging by my drummer situation it's gonna be a while before I can try the GK in a band setting, but I'm hoping that because I've managed to jettison a guitarist and go for a three-piece band, I'll still be able to cut through nicely. I'm going to have a fiddle with it later (no sniggering at the back), to see just how much I can push it. The reason for switching to a 2 x 10 was purely a weight saving decision, as my back is not as strong as once was. My understanding of power ratings is (was) quite limited, (no sh*t), so thanks once again. [/quote] Cut lows and bump mids, the lows are what push speakers to the limits, mids are what you hear. Sounding a bit rubbish on its own doesn't matter so much in context.

[quote name='ficelles' post='1329476' date='Aug 6 2011, 01:21 AM']Celestion Blues Alnico drivers... 15W power handling, retails around £190 per driver. That's one helluva pricey 60W 4 x 12! I think the Gold series is even more expensive... ficelles[/quote] I don't think those are for 4x12s. They are for oldschool bluesy things with a combo that looks like a small suitcase. Making guitar speakers is too niche for going out of your way to please them when they are happy with their inferior products. They still buy telecasters and Gibsons with comedy detachable headstocks.

I guess the simple answer to the original question is because he didn't want to learn his way around a whole new bass. There is a lot to be said for familiarity of an instrument.
