like fidge said, Solid State Mosfet amp = cheaper but needs a bit more know how Valve amp = more expensive generally but after youve got your head round it its a bit easier to build. one thing to bear in mind is that valves need to use mains voltage and so you need to know what ur doing. like i said in the other thread, im currentlly in the beginings of building an 18V solid state amp for my AS level electronics project so i will put up info on howthats going. i might actually start tonight also another thing, (more useful for UK guys) if any of you know the rapid electronics distributions company thernyou may be interested to know that they actually sell valves and they have prety much all the stuff you willneed to make a valve amp. i shall be doing more research on this subject soon

i just had a sex wee these bodies are so unimaginablly amazing i cannot believe it. i would sell my sister for one of those

man you do realise that sustainiac does a 7 string version of their sustainerfor an extra $50

fair enough guys. as i do bits of my coursework ill post them up here/ bear in mind that not all of it will actually be useful (testing the ting ot see if it fits in with my original spec) and that it wont be an amazing amp since its only gonna be working off 18 volts lol and will have just a pre amp and power amp

the hairnever really gets floppy. it just gets curlier around the edges. and the rank chin beard is my very own. during my gap year when i am finally able to grow it to its full potential it will be red and done in forked plaits

Public school birdage are pretty fitty arent they btw i realise that this is all completelly off topic now but since i startedit i can hijack my own thread if i want to lol oh...and for your viewing pleasure. heres me in said tail suit, supposedlly i look damn sexy inthis according my my g/f and her friends lol

LOLOL mkay this is amusing Im actually currentlly doing AS leccytronics and this term we're doing our project work, building and designing circuits etc etc. my initial idea was just do make a small amplifier to run a pair of speakers off my minidisc player. however after my teacher spoke to the head examiner about all of our projects and he was told that itd be alot better for me to just build a guitar amp lol so thats what im now doing. admitadlly its only gonna be an 18 volt solid state jobby but its still an excuse to play about with it lol. if youguys want i'll put stuff up here as i go.

Mains voltage is scary, this is why i havnt built any amps yet lol. if you can get ur EE friend on the case hotrock then please chuck any info from him this way lol. the only reason i understand electronics well is because ive done school courses and i also research guitar electronics and FX designing in my spare time (yes...i honestlly am that sad ) FX circuits are not too hard to get ur head round in general tho alot of it can be very tricky

lol im hardlly what youd call a higher class of person. i may be around a high proportion of lords and earls but i try to distance myself from the "Hoorah Henries" as i can. unless you actually saw me in my penguin suit (yes i do have to wear it. am sitting here in my tail suit as i write this) then youd be hard pressed to mark me out as etonian

thats a damn good idea when i get round to building my guitar im planning on having that sort of thing for pickgaurds and cavity covers. makes things alot easier if you're changing electronics alot lol

do you plan on having coil tapping? if not then find out which ones from the hotrails and the JB are for coil tapping and just tape the ends up so they dont get in the way and touch ground accidentlly. then what you need to do is work out which ones are ground and just solder them to the metal case of the 5 way switch and then a link from that to ground. after that you need to solder the hot lead from each of them to the corresponding tab on the 5 way switch. that you'll have to work out for urself unless you can get a pic up lol

£45 for some of the seeetest tone ive ever heard. best bag for my buck ive ever found. i just love the way that its so versatile as well. i can go from happy punk to emo punk to metal rhythm to blazing lead all by just changing the gain setting and my pickup choice

sounds very much like its the switch thats buggered to me. you might wanna see if you can open it up and clean any contact points

Ur in slough?? quality. im actually at school at eton lol

Atm in my room here at school i have 2 old dead bass amps sitting around that i got off one of the music teachers i know well. they both have metal chassis, cabs, transformers, pots, everything. im planning on building an amp outta one of them at some point tho i need to work out which tags on the transformers are which voltage lol. tbh atm what id really like is just a very simple valve amp (single valve pre amp and Class A single valve power amp output). it wouldnt have any overdrive/gain settings, would be designed so that on its own the amp just gave a very nice clean sound and it wouldnt have any EQ setings. the reason for this is 3 fold 1 Distortion would be provided by my Jackhammer overdrive pedal so having overdrive on the amp as well would be a little sillah. 2 EQ settings are gonna be taken care of when i get my Big Fat Homemade MultiFX rack sorted out. its gradually making it down on top paper, plan is to have Sustain, Delay, Reverb (done with a slinky spring reverb tank), a Treble Booster and an EQ 3 Less stuff needed for amp means cheaper. since i already have alot of the stuff it shouldnt be too hard tho i need to work out how to design valve amps properlly lol. solid state amps are cheaper to build tho you actually need a bit more current know how to do them.... basically quite a few valve amps have a power amp section that has only one valve in it (Called a Class A Amplifier). this means that the entire signal goes through the one valve. the drawback of these is that they're not very efficient. about %60 to %80 of the power that goes into it is given off as heat from the valve. solid state amps that use mosfets to amplify the signal have 2 mosfets in them. they work by having one mosfet amplify the positive portion of the signal and the other amplify the negative portion of the signal (these are called AB amplifiers. Some valve amps are like this as well) the pro of having the 2 mosfets is that the amps are much much more efficient, about %80 upwards. the drawback (and this is where you actually need to know about what ur doing) is that you have to bias them to get rid of crossover distortion. this is caused when the signal being fed in isnt actually large enough to get the mosfets to work (they need to have about +- 0.5 of a volt across them to get them to turn on basically when this happens the mosfets turn off each time the signal dips across the positive/negative boundry and so creates nasty distortion. to get around this you have to bias them by making surethey always have a small DC voltage across them to keep them on. getting it right requires knowing what ur doing there's some of my thoughts on it. tbh it would probablly be easier to build a valve amp however it would be more expensive. what it comes down to is how deep ur wallet is and how confident you are about learning some fairlly advanced analogue electronics off the internet. btw sry if some of this seems condescending to people who already know about it or its a bit totechnical for people who dont. please feel free to ask or abuse

you can buy graphite lubricant which comes in small pots with a thin dripper top i think. if you got a new nut such as brass then you could just use that. its basically just thin instrument oil with finelly powdered graphite in it so it shouldnt cause problems with finish etc

my Kramer was made in korea. tbh i dont really care lol. it plays so nicelly it doesnt matter to me

personaly id just make a small mixer. it wouldnt cost any more than about 10 bucks to make unless you put it in a nice metal case.

oh my bad. seems that having a pot on the oscilator you can chage the pitch it changes to each time so i reckon that you could have a foot switch there *note to self, read things properlly next time*

lovekraft ive found that but as far as i know it isnt posable to add a foot pedal to dynamically change the pitch. you can only hitthe buttons to flick it up and down a pitch

I bagsy every sludge filled, overlly distorted, drop C tuneing powerchord under the sun

wow i didnt realise it was as much as that. i thought it was only slightlly more lol

anybody know where i might find them?? im planning on playing about with making my own pitchshifter and so id quite like to find out what ICs are used in this cheers

lol fair play ive held 600 GBP which thinking about it is probablly worth more than that pretty little pile you got there on the global market lol, i love holiday jobs

yy i found the overdrive was just too sludgy for even my liking lol btw where in berkshire do you live?
