congrats on the rig btw, I looked at that deal myself the other week. let us know how she settles in :-)

[quote name='leroydiamond' timestamp='1333569312' post='1603790'] The buzzing may be due to a poor earth somewhere in the mains supply [/quote] this. sounds like it might be earthing better through the bass. which you're touching with your fingers. sounds like the source of the problem and in the wrong practice room or venue could be bad for your health. I'd take the maplin cables (which are probably faulty) back if I were you geez, invest in planet waves or van damme instead, if you can

RMS means 'root mean squared'. It near literally means 'average' power, but because a bases output (like music in general) us full of big dynamics and lots of different frequencies, your amp can put out maybe 8 times as much, if only for a small fraction of a second, as what it can do for averaged over a few seconds of usual playing. there are only really ways of approximating what your typical music program source actually makes an amp and speaker arrangement do, in terms of transducing electricity into sound. so what you're up against is a load of different ideas about what the best approximation is. And that's when the manufacturers marketing geeks get hold of it, and the figures can magically grow of their own accord... Lots are guilty of this, but that's another thread.

Speaker wattage is basically a measure of how much amplifier energy you can dump into it before it starts to distort, or eventually overheat or otherwise become damaged. This depends on materials used in the driver, the quality of the design and workmanship, but also on what sort of testing standards have been used by the manufacturer. all of those are variables. As Steve says, there are few if any formats you can put together where the wattage of the drivers is not simply cumulative. Ohms, and what your amp can do with different Ohm loads, is another kettle of fish entirely, not to be confused.

I'd take the pedal every time - in principle the low levels here arent much different from amp speaker outputs. at worst you'd want to replicate the precautions you'd take if you were playing two alternate amp heads into one cab, to be sure of its reliable and safe operation. the pedal is almost certainly going to be less faff on stage, and there's no danger or at best, oddity, between two directly connected preamp outs.

Hello everyone just saying hi. I'm a long time lurker joining up because i'd like to get a little more involved with the conversation. its coming up to new amphead time so do expect some amount of wordlage in that department. Im a sort of sound engineer by trade so (hopefully) of some use the day you find yourself tangled up in in cabinet impedances or the whole shooting match starts to do something it shouldn't. Gear as it stands is a matte/ textured black Sub 4 and a dreadful Peavery combo. No pedals in the equation yet, but always on the lookout for nice new shiny things. As a word of warning, I'm a reforming guitarist and a recovering drummer, (i still love both tho), so do bear with me if i say anything peculiar. Or stupid. ;-) Cheers, ears. R.
