Truth_David, gracias por ofrecerte para hacer algunas traducciones, la vedad es que intento postear lo minimo porque se las limitaciones de mis traducciones y pueden llevar a confusiones, en el post anterior queria decir que haber si Col que es uno de los que mas han desarroyado esto, al tener conocimiento de calculos sobre los filtros paso-altos y paso-bajos pudiera de alguna forma implementar el circuito expuesto antes, para tener los modos mezclados de su circuito para adaptarlos al mio, tambien le dije que si queria le puedo mandar algun tda7284 para que el pueda experimentar con el, y comprobar por si mismo lo que es capaz de hacer este circuito, pues de todos los que he montado para el sustainer este es el que mejor ha funcionado en todas las cuerdas y trastes, la mayoria de los demas circuitos que he probado y no han sido pocos, siempre hay algunas notas que se resisten a vibrar, cosa que con este integrado no pasa, es decir ni siquiera con el circuito de Col que es de lo mas avanzado no he alcanzado lo que con este ultimo. Saludos y feliz Navidad a todos

Col, like completing for the mixed mode? If you can have if it sights and you can do it with the minimum of components, since I of mathematical filters and calculations do not understand much, my electronics is very basic since what studies it was the repair. Pete, I feel much that the translations are so bad, to my also costs much to understand many things to me, and some times I remain by halves, mainly in some interesting aspects that I do not finish including/understanding, but good that we go to him to do, to see without with the schematic ones we are included/understood better, and another thing I am of Granada-Spain. If something entendeis, not to ask it well and to have if I explain it of another form that is understood. Thanks for everything

Col, if tda7284 you do not locate it, podria to send one to you, is very cheap about 2 or 3€ approximately. Almost all c.i that you have said to me already I have looked for them and there is no form to obtain them here, sees that c.i estan by zones. The one of the overtones I am trying to do it with tl072 using single one and seems that in the simulator it goes well to have if I have time and I do it then almost all I am doing it in the work and I do not have left long time, as soon as she has it all I place it fixed in the guitar and I raise sounds Greetings

Col, I can assure to you that fizz is no the notes are clean in any fret and cord the form in which I am verifying it is with a loudspeaker in series with the coil and the sound is clean, when can I put some sounds so that you hear it, tda7284 here in where alive there is it in all the stores of components, and in one of them me they have requested it in smd and they said to me that the week next me they bring, so I do not believe it that this absoleto, on the CI. of class D they estan here but difficult to obtain then from 1w single encounter tda7052 although this is btl if you know some between 500mw and 1w I can ask and if there is it here I verify it I say you that with this circuit the volume potentiometer I have it to the minimum so I think that with 500mw tendria sufficient and less consumption, I think that perhaps it is by the cleaning of sound and the exit that tda7284 has that sera discharge. Col you think that the overtones opamp can be made without another one?

Here this my circuit, to see if somebody is animated and it test.

in the first place as soon as it draws it I put the scheme to see the form that it works with the overtones without but c.i in that I believe that Col can solve it, by the others I use dual fine coil of 4ohmios each one that is as I have it in a guitar and in a other fine coil of 8ohmios and also this works perfectly that is to say, with the two coils very well and in addition note just as in the circuit of Col that before decaying the signal increases quickly, much more fast that in the one of Col, the batteries which I have proven are with 3 and 4 normal batteries r-6 and as much with 3 as with 4 works perfectly, although no I have been able to verify the consumption, but they have been 3 or and they have 4 hours not consumed hardly, because they were not new and I have not noticed that lower so I imagine that it does not consume hardly, and the notes even stabilize enough good in all the frets in fret 24 of my ibanez, single it lacks the harmonic way which to see if Col happens something to him not to use but opamp and to maintain the circuit with the minimum of components.

Col, the overtones in your circuit are investing the phase or by filter? the circuit I have fact with tda 7284 and tda7052, works from 3,8v. to 6v. perfectly and in all notes, single I need to fix the one of the overtones and for that reason queria to know if by means of passive filters it is possible to be done, with two c.i podria thus single all the circuit being very easy to do and with very few components. When this ready one I raise it. greetings

Col, that simulation software you use?

Col the circuit this or, the condenser of 47 uf this in the switch that I have position, and the circuit I in series verify it with a loudspeaker with the conductor but single for the operation tests, in also fetzer I prove it thus, and when proving it it is when I have noticed that oscillation or interference rather, and by the verifications that I have done is of the first stage of preamplificacion.todos the condensers estan in its site the bad thing is the translation of google which I use and often it does not translate or. In any case the circuit works very well, although I notice it that a little slow I spread must raise the volume, perhaps is by fet that I use. on the other hand I am making another circuit based on tda7284 which has a ALC (automatic control of volume) along with tda7052, to feed it 6 volts and the tests they go enough good and the circuit enough is reduced, in the tests I am using 2 tda7052 one for each coil of which one of them is for notes but high and the other for all when it has it working I put it.

Hello, or I have corrected the errors that tapeworm and the circuit works perfectly in smd, Col, when proving the circuit with a loudspeaker you have noticed certain oscillation when using lm386 or if on the contrary it is heard clean, because when proving it with the loudspeaker I have an oscillation that using another amplifier as tba 820 of 1w disappears but seems that with tba820 it has the less power when deberia to have but that with the 386. Also I have proven with the TDA7052 and it does not give the necessary power either, perhaps the 386 it needs less signal entrance and for that reason it works better than the others. Greetings

Col, I finish verifying that the bridge between +9 r-12 and r 26 and this fact. c-9 I have like c-1 and this position. my conductor works well with fetzer. fets is where I have the doubt when not finding j-201 I have position k246 that according to where it buys it is equivalent. The harvesting is one evo2 proevolution of dimarzio and has a high exit. r-27 if this connected to the Pin5 of (IC1) and with the external connection of the way switch b1. But in my disposition of the drawing they estan superposed the names since eagle puts them automatically. that is to say, upon r-29 it puts r-27 and upon r-27 it puts r-29. in my drawing there are some different names, to see if I correct with respect to your scheme corregire and I put it. Also I have bypassed r-31 of 12k and now this working better, but still him lack a little power mainly in low notes in the cords to the air mainly, in the high frets from 5º to the 24 enough good. Thanks for everything and to see if we obtained that it is envy it of the patents. (Col, I finish verifying that indeed the problem is that habia seen the cuts underneath r-19 and r-29 as soon as does not prove it I comment to you, but I am convinced that he has been that.)

Col, I have made your circuit in smd, but I have a problem instead of lm 358 I have put tl072, because nontapeworm the 358, and does not have sufficient power to maintain in many notes, not if sera east the problem, you think that deberia to work with tl072 or tendre that to modify something?

Everything is for superficial assembly, and in double slide, + of the circuit and the negative as well as points 1--1 up to 5---5 go united from a face to the other, in addition 3cm x 2cm is of each one of the sides, it is possible still to be done but small but with system DIY to make serious the plate complicated because the tracks are united or they cut when they are tried less of than 0.012 of thickness, I am mounting it and when it has pondre photos. Pete I feel much everything what this happening I hope that it soon to you solutions, a friend. greetings.

Here this the circuit of COL in smd. that seems to you? salu2.

Col thanks for your circuit is perfect, what hare now sera to design it for smd in the minimum space, if it can be in 2cm. x 2cm. com tda 7052 in the place of the 386 including. Pete, I think that the fine conductors podrian themselves to use in the single average position a coil but must be isolated of EMI, I I have proven this in my ibanez and works enough or, for it as in other occasions I have used very fine tin strips having surrounded the coil until reaching the size of the average harvesting practically annulling almost all EMI towards the sides and without using nucleus in the single coil with the magnetism of the harvesting, and to thus it has worked me or in the average position and that that evo2 is enough hot in the other guitar which I have has the harvesting lace sensor of fender and placing it until almost a cm. of near the harvesting does not have interferences, I think that deberias to prove it, single is necessary to cut strips of 2mm. of tin of the pepsi-cola and to surround the coil until 0,5cm by thickness with her, and almost is annulled EMI, with the bilateral coil I have not had better results than with which I have put. Also to comment that the thread of the coils like was impossible to obtain it in stores, here in where alive, which I do is to buy motor of ventilators of 5watios, which take thread of 0,20mm. and they take off very easy which can have thread for 18 coils it comment for which it does not have possibility of obtaining the necessary thread. Greetings

Col I thank for that you have put your circuit to the disposition of all, the only thing is that I lose a little without the scheme, if you can have if you comment a little to me the modification for the system mixed in comparison with the circuit that I put in previous post to do mod opportune, thanks for everything.

Pete, I am using a single fine coil with tba820 of 1w, but single to prove and other 8 times I use two of ohm fed with a stereo amplifier on 1w. Still I do not have safe what pondre in the end, in any case I finish buying two tda 7052 to prove them and 7052 both thought tapeworm to use each one with a coil of 8 ohms, mounted upon my hambucker, all fact in one laminates very fine, and if the circuit of Col is perfected not to use electrolytic condensers I believe that podria to make to mount it underneath hambucker and thus not to have to touch nothing in the guitar except the commutator. The truth, I do not want to modify nothing or almost nothing in my guitar, the subject of the batteries I have it solved with 6 small batteries of 600mA. each one between the cavity of tremolo, and underneath the potentiometers of the guitar, the system to disconnect the harvestings is very simple, a switch of car radio that in fact what does is to connect the feeding when the harvesting of the bridge is selected. Thus it is as I have everything. Greetings.

The circuit is of 2,5cm x 2,5cm approximately each one, although I can reduce it but but no longer prodria to be used nothing else that smd and thus can also be done without smd and they are possible to be put both in a single plate of double track, to see when you surprise to us with that improvement in the mixed way and I modify it. this already I have fact practically for want of the potentiometers, all I have made it with smd of cdrom old and some pieces removed from computers as soon as have it I put some photo. Col, if you wish it I send the complete project in zip.

Good morning friends, I put the image to you of the circuit of Col in smd here to see that so it seems to you and if somebody wants him to it I can send the complete project done with eagle 4,15, I have not reduced much to it to be able to also do it without smd, also I have divided it in two to be able to place it but easy, in the guitar. Another thing the coil which I proposed in horseshoe form I have to say that he does not work as he hoped and the design of a fine coil until now is the best one. Greetings

as soon as my project of the coil in horseshoe form finishes to see as it works, also I put some photos now that I am winding it. Pete, this was what I queria to explain to you with the drawing in post previous. Thus with this form of erradura I try that it has mini EMI to see if it is possible to place the conductor in the average position of the guitar. Saludos desde Fuente Vaqueros- Granada.

This is my new amplifier 1 watio, uses tba820. this is my preamplifier, 3 band equalizer. this is the following thing that I am going to verify if it works well, 1-single amplifier of 1w. 2 - if it does not go with the preamplifier and equalizador well.

For the subject of the commutation we have the 4017 which I have used in other projects along with the 4066 and goes very or without noise in the commutation and with possibility of exchanging many circuits that if sequentially, it comment by the subject of the programming of pics, that many do not tendran whereupon to program them or can be them complicated, for that reason I propose east circuit that is very simple and all the circuits can be exchanged that we wish. Salu2.

that so this previous one with ALC to make level the signal level? , it can work? , or somebody can simulate it. Basdo in developed integrating for cassette recorders, which includes in its tablet circuits of automatic control of level, is able to make level a signal of audio without concerning its original level.

Then, to have if I find out to me, that the translators I do not end to find out very well that it is what looks for, I create to understand that what we needed is a type of compressor - limitor that acts with the signal before the amplifier, to cogovern if is thus. if this is thus what we needed is a control that acts on the amplifier but controlled by the signal of the harvesting. is this thus?.

I believe that podria to solve many problems to us, if the frequency becomes tension this can control the gain of the amplifier, for it I am watching some c.i like lm2917, TA8029S ta7715 etc.
