Mr. Foxen

If its an American one with a dual action truss rod and graphite rods, might be the neck is reluctant to respond to the truss rod, I found a bass with a reinforced neck took time to actually shift once the rod was adjusted.

I bought a pickup, quick and easy, cheers.

[quote name='Roland Rock' timestamp='1344665310' post='1767688'] Sorry if this is too OT, but has anyone else been looking at the speakers at the Olympic Stadium in terms of dispersion? Quite a challenge. Each 'stack' hangs high, and is vertically aligned. But then the stacks are arranged horizontally around the stadium. [/quote] Far enough apart (like more than two wavelengths) and interference isn't the issue any more.

Had aYBA200, its fine, but not especially valve sounding, which is kind of a win for a well engineered amp, being not really coloured and distorted, but might be better served elsewhere. The are less expensive than Matamp because they are mass produced PCB amps, they are less expensive than Orange because they don't give loads away for exposure. I didn't take mine apart to assess build quality, but it did fall out of the bottom of a flight case and play the gig.

[quote name='alexclaber' timestamp='1344465122' post='1765162'] If you're going to try to do an actually useful and representative scientific test then you need to make it as much like a gig as possible, with all the interesting acoustics, noisy bandmates, variable audience, etc. [/quote] No bandmates, audience of the same half dozen mates, fiddling with acoustics is all of the point of my set. Is my music science?

[quote name='oldslapper' timestamp='1344447560' post='1764733'] Lead bass? [/quote] The sort of bass playing you need to wooly ill defined tone of a shortscale with a neck humbucker for.

Listen the guys voice to get an idea of how the youtube vid reproduces stuff. Problem being everyone is used to recorded voice, but the artifacts are there if you listen.

Set up a turntable somewhere without reflective surfaces around it, that would be a good dispersion demo, spin it like a Leslie cabinet.

A high pass cap, and a low pass cap.

Guitar rig for the moment, likely to be absorbed into the bass rig shortly though: [IMG]http://i17.photobucket.com/albums/b69/Incarante/newstak.jpg[/IMG]

[quote name='bremen' timestamp='1344364602' post='1763490'] That'd work. You could design an output stage that'd go 'bang' into a 4 ohm load were it not limited. Flick the switch to '8' and it'd be unleashed. Bit risky though, what happens if you run it into 4 ohms on the '8' setting? [/quote] User error invalidates your warranty. Plus Orange cabs will pretty much all be into fart territory before 500w hits them, except maybe the big ones that will have levelled the room by then.

[quote name='JPJ' timestamp='1344360441' post='1763356'] So does this mean that the marketing stating that the full 500 watts into either 4 or 8 ohms is a complete fabrication then? The impedance switch is merely there to ensure the correct filtering load for the class D amp? [/quote] Watts is pretty much a fabrication, since it's dependent on outside influences, and only quotes a nominal one. The correct filtering load would influence the watts too though, since the purpose of the filter would be to remove the distortion from the amp, although I don't know if it counts as harmonic distortion for the THD figure, which is necessary to quote to give a useful output figure.

I'm thinking the fuzzy bass that covers guitary territory crowd, power trio and suchlike, EB3 territory. Power duo with enough amps.

It sits at the guitary end of basses, its much like a tele and shorter scale. That has an appeal.

Using the speaker as an inductor for the low pass filter that takes out the switching noise from the class D output saves components and makes the amp cheaper. Cheaper to make at least.

Kind of wonder if the switch even does anything at all, not like anyone would know. Switch and a dymo labeller is all it takes.

[quote name='paulflan0151' timestamp='1344287643' post='1762386'] I've always wondered about the quality of the modern ampegs, seems like they've been living off their past reputation for a while now. In saying that I've never played a top valve ampeg. [/quote] I've poked around in a holy grail type original 69 blue line SVT, and quality wise it really isn't anything special, they weren't quality items they were good enough and cheap enough that lots of people bought them. There are a lot more Fords about than Rolls Royces, doesn't relate to quality level.

[quote name='paulflan0151' timestamp='1344283314' post='1762307'] Ampeg. Why didn't I think of that? They have some pretty ampeg stacks I'm pmt in Manchester. Might go down and have a little look. Although, I've heard there made in India or somewhere now and I'd begrudge paying top dollar for a cheaply made product. I'd like to buy UK if possible. And there's the price! I'll have to get one of those proper jobs to afford one :-S One of those soul crushing, mundane jobs rather than making guitars for a living! Oh well. Thanks for the posts fellas. Been a real help. [/quote] Find a custom amp builder, offer to build them a guitar. Only ones I know can also make guitars though, but there'll be others. The eastern man Ampegs are comparable in build quality to US made ones, so yeah, cheap.

Don't even mention the concept of mobiles to Steve at EL. Only real way of getting hold of him is to turn up there. Edit: Unless the moon and planets align and the appropriate offerings are made and he is allowed to walk the earth once more, then you might bump into him about the place.

[quote name='paulflan0151' timestamp='1344265313' post='1761937'] Thanks for the reply guys, I was supposed to go to the Matamp factory the other week but was too busy. I'll have to re arrange. I've always tought of Matamp as more of a rock sound. i'm after more of a old school funk. Although, it should be said, I've never heard a Matamp. Well, I'm after something old school sounding but can do somthing a little more hifi too. A guy on here is selling a Markbass valve head which looks up my alley. But again not heard much about them (classic 300). Edit: Im not too fussed about weight. And I'll deffo have a look at the EBS valve head as I loved the old EBS SS combo I had. Thanks again chaps. [/quote] Matamp are pretty clean unless you want them to dirt up. The big fuzzy thing they have an internet rep for was down to an American dealer putting 6550 into a EL34 guitar amp and selling them as 'bass amps' at a premium, meaning they distorted loads from running the wrong valves, then blew up.
