The sensitivity of the 4x10 is 97dB the 2x10 is 95dB.

[quote name='ironside1966' post='1083165' date='Jan 9 2011, 02:30 PM']From my experience the bands that busk tunes rather than learn them properly tend to be in the in lower paid gigs.[/quote] Is this chicken and egg? Do you get better paid gigs because you have put the effort in or do you put more effort in because you are getting paid more?

Going back to my example with my previous band. There are a lot of musicians who will listen to one verse, one chorus and the mid and then announce that they've got it. Hence the problem when it all falls apart in the third verse, or when the band can't get the bit where the mid section goes into the chorus instead of the verse. Now most tunes have differences in each verse and each chorus. So where I'm coming from is not necessarily nailing the parts exactly but understanding where and why the parts differ in each verse and chorus. Usually the bass line can be picked up in one or two bars, it's the subtleties that take the time to pick up and it's those bits that people don't bother with. Hence blandly busked tunes.

Unless you are a perfectionist of course... [/quote] Because in most cases you only need to do quarter of an hour and it's clear that some don't even do that.

[quote name='AttitudeCastle' post='1082484' date='Jan 8 2011, 07:28 PM']... I've always thought when it comes to writing music. Listen to the music you like and want to write, and find the common thread between the bands and songs you like and use that as a spring board, ...[/quote] Listen to something from other genres and play along to stuff you wouldn't normally listen to. Might add a different dimension to the way you think musically.

Feel is essentially [b]how[/b] you play the notes. Some people have good natural feel, others have to work at it. An extreme example- Imagine Steven Hawkins reading versus Stephen Fry. Then imagine Steven Fry reading poetry and imagine him reading Harry Potter. You're probably playing all the right notes in all the right places, but some notes should be long and some short, some have more emphasis than others. You are probably doing this already but the length you play a particular long note and the way I would play it will be different. That's your feel vs my feel. There is also advanced stuff like playing ahead, on and behind the beat, laying back, pushing etc Music isn't just about what notes you play and when its about [b]how[/b] you play them.

A can't think of many basslines that can't be picked up within 15minutes of listening and playing along to. You really need to [b]understand[/b] how the line you are playing fits with and affects all the other musicians before you decide to change it and consider whether it really needs changing. In my old band we had a problem. The vocalist and I really struggled with one line of one verse in one song. Everytime we played it in practice we seemed to stumble over it, when we played live sometimes the tune would almost fall apart. In the end I recorded us playing it, took it home and compared what we were all playing to the original. On the original and the recording, I played triplets along with the vocal melody. On the original the drums, guitar, and keys all played a single note underneath the triplets. On our recording, the drums, keys and guitar were [b]all[/b] putting in fills without the triplet feel. I asked them about it and they all said it sounded empty so they were adding to it The mad bit was that they obviously were not listening either to each other or to the vocal line. This wasn't the only song I had to resort to listening to the original because of car-crashes. They're having real bad problems with the new bassist who continually ad-libs and doesn't stick to the bass line. OK in maybe a three piece but not a 9 piece! Poetic justice. The car-crashes happen in my new band for the same reason, the guitarists haven't listened to the original closely and are playing something that aproximates (or doesn't!) I went to an audition where I had been told that the guitarist auditioning me was a stickler for accuracy. I had spent a long time leaning 5 songs very accurately. We played through the first tune and at the end he asked "Is that how you think it goes?" At the end of the third song he says "Ok I don't think you're what we're looking for." Win some lose some. A problem that I see a lot is that you learn a tune and over the years embelish it a bit here and a bit there. After a couple of years the tune bears no resemblance to the original. "That's how we've always played it" No mate actually it isn't!

I don't know what the manufacturers use as a 4ohm load. If its a speaker then at a sine wave of 1khz a 4ohm speak is NOT 4ohms. Neither is an 8ohm speaker 8ohms. It'll be different for all speakers. We're also talking about a reactive load so there will be phase differences and all sorts going on. DC theory will only get you so far. You just have to content yourselves with the knowledge that transistors are NOT linear devices. Look at some current curves. You can-nae break the laws of physics.

[quote name='Mr. Foxen' post='1081654' date='Jan 7 2011, 11:38 PM']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[/quote] The opposite. Silicon has a negative temperature co-efficient of resistance once it gets over a certain temp it will go into thermal runaway. Hotter it gets the more current it passes, the more current it passes the hotter it gets - queue blue smoke. There are lots of ways to try to stop this such as by piggybacking transistors so that as they get hot one drains the current away from the other. This again impacts on the current the amplifier can drive.

It's not the power supply. It's the characteristic of the device that is amplifying the current. The power supply just supplies the current and voltage to that device. The current still has to pass through it. If you want a more powerful amplifier then you just get a bigger device, but that means more cost. Hence more power = more cost. You're still looking at it from the wrong angle. The maximum power is determined by the maximum current through that device. The 8ohm power is then a function of the full power at 4ohms. It's not that you can't get double through 4ohms it's that you get more than half at 8ohms. As Bill intimated earlier. The power output is not linear. This is why you get power compression at the top end of the amplifiers range.

What?

Its not a case of not being able to get double the power out of 4ohms, more a case of being able to get more than half out of 8ohms.

Amplifiers are current devices, not voltage devices. The power is limited by the current it supplies. If the voltage rail maximum is 50v then into 8ohms you get 312watts which is 6amps give or take. With the voltage rail still at 50v then theoretically into 4ohms you'll get 625watts but if the amp is limited to 11amps then you can only get 484watts. It's not the transformer it's just the way that the transistors or valves work.

Part of my job is to source parts. Email is OK, but not for everything. The trick is to know which type of communication to use for what. Often I'll email a retailer and don't hear anything back. After a day I'll call them by phone to chase. Usually they've passed my email on to their supplier and forgotten about it or are still waiting for a reply. Very rarely do they ignore it. My standard approach is email the technical details. Wait 24hours and if no reply then call to check they've done something about it. If its not a technical question eg do you sell X or can you get it for me? Then you should always use the phone. There is a ringtone I can't stand due to a manager who used to call constantly to check up on where I was.

[quote name='terryblyth' post='1073008' date='Dec 30 2010, 07:03 PM'][/quote] That's the one. I was wrong. The last three notes of the run down are the same and its the keys/guitars that are playing some strange inversions. I knew it was something odd. That brain cell is being used for something else nowadays.

The last three notes of the run down and the first note of the chorus (whatever they are) are played over the same single chord that the rest of the band plays. This is why it will sound right when you play it to the recording, but not when you play it solo or if you play it with your band and they don't get that chord right. Most of the guitar tabs on line don't have it right either, guitarists always seem to want to play the bass notes as well! I did work out the chord about 5 years ago but can't help you with it now. sorry!

[quote name='redstriper' post='1067661' date='Dec 23 2010, 11:57 AM']It's only since deciding I want a new one and joining this forum that my problems began. ... ... I live in the sticks and don't get to see many new basses and all the ones I've tried sound and feel horrible because I don't like round wound strings. ... ... When I asked what they sounded like, he said he hadn't plugged them in to an amp, because they'd all sound alike depending on the player - a man after your own heart eh![/quote] Forums have their good and their bad points Have you thought of buying a set of flats and taking them around with you. I'm sure any decent shop will allow you to restring a bass if you find you like the feel and want to try before you buy. As long as you don't spend all day restringing bass after bass. I've found that the more experienced salesmen will leave you with the bass and tell you to ask if you want to try it with an amp. The less experienced will be plugging in the leads before they've found you a stool.

[quote name='Vibrating G String' post='1067424' date='Dec 23 2010, 08:07 AM']... like a piano player who can't swap out pianos all the time. ...[/quote] Excellent point. I'll ask my Dad. You don't see pianists changing strings, or pianos every few months. What other musicians are there that obsess and swap instruments so much?

[quote name='redstriper' post='1066952' date='Dec 22 2010, 04:43 PM']Why not buy something that sounds bad, if tone doesn't matter ? In fact why bother listening at all ? Your 'sounds good' will not be the same as mine - tone, like everything else is subjective and I want to 'sound good' to me, not you.[/quote] That was in the initial post and I've clarified what I meant by it since - endlessly searching for that 'elusive tone' to the exclusion of everything else, rather than accepting what your ears are hearing. In fact the two examples Marcus Miller and John Entwistle are really quite interesting. Marcus - was given a bass and made his sound from it - legions of bass players are trying to get that tone. John - Became a millionaire after the song My Generation was recorded and then spent the rest of his life looking for some mystic tone that was in his head. Ironic considering that most people think of his tone as being the best on My Generation.

I used to be a critic. Now I just watch and enjoy. Occasionally I'll discuss their performance if I'm with another musician. Mostly I'll try to be positive about everyone I see. It's not easy to play live and anyone who gets out of their bedroom and puts the effort into rehearsing and playing a gig deserves some respect.

Funny enough I spent about 7 years looking for my bass. I didn't buy any others because I couldn't find the right one. I enough saved from gigs to go to about £2k but couldn't find anything at all that spoke to me. Ibanez SR400 for me £499. The only criticism is that it IS a cheap bass. It sounds great, the neck is good, the pickups are great. The bridge is a pain when you change strings. The machineheads aren't great and I replaced the whole lot of them like for like after one sheared off (at a gig!). I'm not changing it - overall it's a great bass.

[quote name='umph' post='1064131' date='Dec 19 2010, 10:46 PM']You seem to be putting across a kind've vibe that insinuates you think people who fuss about their gear are inferior.[/quote] Ok. Sorry, it's not intentional, I think it's just the way you're reading it. No need for name calling Most, if not all, of us want to sound good and we all spend a lot of time looking for gear that gives us the sound we are after. Just I think some lose their way and become obsessive. They can't see the woods for the trees. It's easily done, I just wondered to what degree people were obsessed. From this thread most don't seem to be as obsessed as I thought, but then maybe the obsessives are busy looking for new gear on other threads

I wonder if he had a big influence on how he sounded and was altering how he sounded on the albums then? It would also explain how so many people can claim to own a bass once owned by Entwistle

[quote name='umph' post='1064095' date='Dec 19 2010, 10:23 PM']i build all my own gear so not really searching for it since all my stuff does sounds i like and i'm pretty happy with it.[/quote] Is this because you like how it sounds or because you have experimented and make it to sound how you like. [quote name='umph' post='1064095' date='Dec 19 2010, 10:23 PM']No need to be a dick about people enjoying finding the sound in their head.[/quote] I don't understand this comment.
