What is 'crest factor'? It is probably maths, that they tried to teach me in school, but did it without context.

Bass Xciter.

[quote name='Phil Starr' post='1085940' date='Jan 11 2011, 07:25 PM']If this is the sound you like then why not go for a couple of lightweight active PA speakers?[/quote] PA speakers tend to not go very low, because for PA purposes you have a sub to cover that when it becomes necessary. Plus your vocalist will assume he can use them.

Is there a wah of getting a response chart cheaply, from your PC or something, using some live level output from your amp?

[quote name='51m0n' post='1084000' date='Jan 10 2011, 10:41 AM']Barefaced Super12, Bergantino AE212; take your pick. Hartke LH1000 bridged or LH500 if you like.[/quote] Fairly sure those aren't flat, the use a classic passive valve eq, which is fairly far from flat, as pleasing as that voicing is.

Are the handles on those peavey 2x10s side stacking friendly? I had one and totally don't remember.

That is a bit balatant, but stuff like this means quality has to speak for itself, rather than letting a brand label speak for it. Which is a win for the discerning consumer, issue being most consumers aren't discerning.

Barefeced Big One or the 12" version, a PA tpye power amp and a really simple clean preamp, possibly one not intended just for bass.

I post vids of this lady whenever someone goes 'I have small hands so I need a skinny necked/short scale/miniature bass instead of learning how to play properly'.

Those heads are great, and the value of watts is vastly overstated, no real point in changing cabs to squeeze more watts from the head. You shouldn't struggle with 200w into that cab unless you boost loads of bass or detune loads, and the head will be running nice and cool (mate of mine melted the transformer in his by running it at half an ohm and bypassing the safety trip), even if you add another cab. Those heads are really good, using the valve section will give you some compression and drive and make the most of the power, if you wanna be louder than that, you'll need a second cab.

[quote name='flyfisher' post='1081702' date='Jan 8 2011, 12:31 AM']Fair point about DC theory not being strictly applicable, though it's one way of 'visualising' what's going on - to a very rough approximation anyway. Given, as you rightly say, all the variability involved with music waveforms and speaker behaviours, it's a wonder we bother worrying as much as we seemingly do with precise 'matching' of speakers and amps. But I guess describing a speaker as '4 ohms' or '8 ohms' also helps people 'visualise' things - to a very rough approximation. [/quote] That is why it is 'nominal impedance', and it isn't DC, because it is impedance, rather than resistance. You get a graph and the nominal is determined from that, there is some sort of rule, which made the Barefaced big one come up as 6 ohm rather than 8ohm due to the crossover, but in the end, the impedance of the woofer was the bit that mattered.

I think heat sinking is factor too. Running more power means it all warms up and the transistors don't work as well hot, I'd guess their internal impedance increases. And beeinf up heat sinks is a big weight gain (see Peavey amps that run to 2ohm).l

The resulting model would then be sold exclusively through Bass Gear but keeping the maker's brand.[/quote]

Shows the power of photography, the wibblyness of the top doesn't show at all. Glad mine is satin, and post that much sanding, it ain't very flat, as I found when I put my bridge on.

Every knob that isn't on full is money you have wasted buying that amp.

Nut type thing at the headstock end. Is pretty choked with paint and not had need to adjust to left alone. Just done a black powder coated steel scratchplate for a mates Rick, totally forgot to take pics.

[quote name='dan670844' post='1080597' date='Jan 6 2011, 11:43 PM']Yep Leo Fender was a genius he did the SE-5 tone stack and deluxe when in the 50's? You really think SS preamps are lame?[/quote] For the purposes of a valve amp, yes. All that other stuff you said, doesn't belong in a what do you want in a valve amp thread, because, as you specify, they are all in amps that are already made. I use separate pre and power amps according to need. Building all of them into one amp would make very little sense. People that want fiddly can make something fiddly out of bits. For the purpose of a valve amp, what I describe is what I want.

[quote name='PaulE' post='1080362' date='Jan 6 2011, 08:09 PM']Someone please answer me something Ive always heard mixed answers of? The quality of squier?[/quote] The name and quality of items don't necessarily really relate, especially not in the case of Squiers. They have been made all over the place to varying price points so the quality of things with the name on varies, but within particular series are comparable.

Also Laney. Doom.

How did control voltage fit in to the history bit, did it just predate MIDI and be not good enough to be useful?

For the people demanding 3 band EQ, check out [url="http://www.duncanamps.com/tsc/"]this program.[/url] I shows how much more flex you can get from a 2 band tone stack, and less knobs is less cost. Going solid state for the pre is a bit lame, and active valve preamps give you the issue SC120 mk IV have with noise, because they have all the noise of three gain stages.
