i was thinking about makign an onboard guitar sampler. i have been an only guitar player for years and i like to make different sounds and such.. over the years i have used alot of delays to sample sounds and play back over them radioshack has a nifty little sampler already prebuilt. designed for voice. but if you change the capacitor there to a film one you can make it function for guitar freq. the first time i did this i put two in a guitar and would record some harmony stuff with it. the second time i did it i put two in a pedal with four seperate switches. record a and record b and play a play b. it can be done on board or in a box what do you think???? ps brian i got the push pull emg style booster coming.

also a chasis well it depends on how big you need it. personally can make a tube amp in the 50watt range in a hammond D box if i had to .. i already do a 8 watt tube amp,(loud enough to spank your ears and the drummers) in a hammond S box

i like 34 grit,, its nice for scaloping taking out the big stuff by hand,, its like rocks glued on paper

theres a couple the ax84.com is a great page to get started.. personaly i would start out with doug hamonds firefly its a great preamp uses ready availbale parts and is pretty cheap to do, and sounds about as loud as a20 watt solidstate amp. it is about 1.5-2.5 watts depending on what tube and transformer you use. http://home.cfl.rr.com/dbhammond/ff.htm read this page it is very helpfull. and it is very easy. its a plexi clone with a twist a reverb driver type tube for your outptu tube. as far as a program to do it for you, hmm i am not sure.. i haven't heard of one. if you tell me what you are looking for, i could draw up something for you. it all depends on the sound you wish to acheive. i do mostly high gain - medium gain stuff. but i also do some squeaky clean things as well. how much wattage do you need , i am currently working on a nanohead type amp in a bigger box, with an extra tube, and an extra gainstage with and eq section.

you can build an lpb1 with a mid notch/peak rc filter in it. and put a resistor on th einput of it, so when you engage, you get a slight boost , but not as much noise. i got something like this around here somewhere

i can draw this up but why not use a concentric pot. that way you can have both seperate tone and volume ontrols.

i can do the coil cut thing with a pot for ya. i wil draw up something later. and post it... the three pickup thing is the same schematic as the gibson triple pickup

thats why you use a nice high power lithium batterie.. rechargable, and charge it wiht a stereo jack and plug..

quite a bit, i have done several little plexi clones that i do lower wattage output section.. what do you need to konw.

i can fix your wah problems there.. or if you want, i will trade you your useless wah as you stated, for the price of the mods on my wah. i modded the carvin ones so an;yway i got like 55 dollars in the raw pedal. for fourty dollars and your pedal i would swap you. or if you want i can mod your pedal for you to sound better. i have an older clip of my modded wah. www.geocities.com/cemaynard1134/sound.htm its the first clip on the page.

ok no problem here, aron, just like myself and everyone else in teh diy world has different terms of descrbing fuzz. i dont' use fets very much, so i didnt' put them in as i am sure there are different levels of diyer here, as there is on any forum, but i tend not to post about what i dont' play with that much.. kind of like this. if you drove a lamborgini would you take it to be repaired by mr goodwrench. anyway i have only found one design that i coudl tell a diference in tath used fets or mosfets. and thats joe davissons amberdrive "What schottky are you using? I couldn't find one with a forward voltage drop lower than a germanium 1N60." i won't say as this isnt' my project i am working on it is brians so if he wants to post the diodes he showed me then cool till then its kind of like ZVEX schematics. i have some but i dont' share out of respect for him. couldnt find a 1n60 datasheet, could you post a link. casue i am not sure what the forward is on it. for shotckys on the input you should check out TIM escebedo's rambler there is a good highvoltage, solidstate, tube emulator but i dont' konw where it is. it uses jfets and mosfets in parrallel acting like a tube.. real sweet i did a low power version in a pedal.. sweet............. but yeah i like tubes better myself, but its amazing what uses diodes in the clipping circuit.. JCM900 anyone?????

Are you from Leicester by any chance innit? Lightbulbjim - you've just described my brother down to the last letter. Ansil - what's your story then, you seem to be a bit of an electronics guru? 20+ years takings stuff apart and buidign with it. 14years+ wiring guitars and such 14+ years doing bobbrahshaw type wiring for fx routing 5+years of pedal making. 3 years engineering in robotics, and computers. top 5% of class. 3.7gpa jobless lol

if you truely want a tweed amp type style you need to look at the sansamp gt-2 schematic and rip out all the high gain stuff, and just use their fender section.. it would be pretty easy to do. if you need me to email you the schematic let me know.

germaniums won't clip anymore than any other diodes.. they will only do it later in regards to siganl threshold. if you are going passive with a black ice type device as in this thread then germaniums would give you more headroom than the shotckys so you would need super hot pickps to make them crunch.. personally my last setup would have cause them to really spank a set of germnaiums .51v into a .3v germanium would have really made shotckys have a bad day. but would n't even conduct a silicon unless i really hit the strings hard. but then again i do play hard, and with 16 on the high E and a 75 on the low E i think i could do it. lol but in the world of stompboxes it goes like this. schotkys on input for an octave type effect. or on a simple 1 transistor booster germaniums for a buzzier sound more fuzz like silicon for basic crunch leds for higher threshold and more tube like sound

i saw that too. of course you could always build a zvex SHO or a Mosfet booster, the mosfet is a pure non coloration device. where as the jfet is nearly pure. depends on how well you perceive the tonalitys of harmonics and such. we did a test on the diy forum and over half the people couldnt hear the harmonic distotrion at 1%. but anyway you could build a SHO or mosfet booster and put it in the guitar.. the current draw is like 4ma so the battery would last for years. my vote is for the SHO i have used mine for quite a while now. of course it ads a little coloration to my ears but it is completely musical in the fact that it sounds better with every gutiar i put through it.

you also have to take in consideration stuff like resonance , and resonant feedback.. you can have the guitar have feedback and never hear it.. when you play it is similar in the fact the way a room will have reverb type reflections, you also have the sound comin back from your amp and will cause certain parts of your instrument to vibate differently than if it was unplgged. this will have either a positive or negative effect on sound on your instrument. when you can feel like your guitar is "alive" and about to jump out of your hands that is really bad resonant feedback. i have seen a guitar crack because of this.

actualy one is an indicator, and it is symetrical distortion un less you really dig in and then it becomes asymetrical depending on how hard you play it. so it is really responsive like a tube amp.. when i demoed the latest version for one of the guys who is going to carry my pedals we played it through an old peavey head that was based on a tube amp from fender not sure wich but its real spankin clean. anyway when i hit the double gain switch i was jammin out some yngwie and it sounded like a cranked up plexi.. he bought the prototype on the spot.

i like the hotstick. i think its cool currently i am trying to rectify the ac signal using small schotkys and a step up transfomer before that to generate enough current to drive a very low power transistor which in turn would power a diode ladder to power a medium power transistor. after some studying i htink it can be done. still looking into it though. this is a block layotu of what i am doing anyway i ahve been up all night and no time to draw schematic http://geocities.com/austenfantanio/DIODE.htm

i have a once chip distortion pedal that realy kicks butt, i could send you a board but i dont' share the actual schematics. cause i sell these. but if you wanted a general layout of it. it is a very theory intense pedal but it only uses one chip three caps one resistor a toggle switch and a stomp switch and three leds.

has anyone ever tried the clyde mccoy wah.. if you havent' you can't really say for sure what you like, untill you have played that one. not being arrogant but that wah does rock metal funk thrash, christian you name it you got it. i had an original one when i was 17 and didnt' appreciate it cause it had mis biased transistors. i got 500 bucks for it though. but i would trade it back to have it back.

that won't really be for sure until you actually get it in there.. i woudl personally shield it myself though

its a preamp

that i dont' know i found one at my local music store

yes this ground would not need to be connected to the bridge ground only the output jack. of course in theory its always good to ground the bridge through a resistor.. preferably highvoltage.
