Hola Hola amigos amantes de la música y el bricolaje, hoy les hablare sobre un proyecto que tenia en mente desde hace un tiempo, y que hace unos dias me dispuse a desarrollarlo, y este dia de hoy con muchisimo gusto y humildad se los muestro!, se trata de una unidad delay al puro estilo Tape Delay, es decir, el típico Delay a cinta (Echoplex y similares). Hay dos factores que me hacían ir para atrás en un delay a cinta. Primero, su enorme tamaño (¡vamos, como para integrar el pedalito en la pedalera!), los componentes son casi imposibles conseguir en mi país, (Venezuela) y comprarlo?, ni de juego después de ver su desorbitado precio. Tan solo la recreación de un auténtico delay de cinta analógico que vende Fulltone ya es como para tener que vender un riñón, así que imagínense lo que debe costar una auténtica unidad Echoplex o similar. Asi que me puse manos a la obra y decidi buscar opciones algun esquema para construir y tratar de recrear ese sonido del mencionado delay, en mi busqueda opte por uno digital pero con respuesta análoga, pero (el bendito "pero"), el mundo digital de los delays se ve limitado por el número de bits con el que se procese la señal y la calidad de los conversores Analógico/Digital y Digital/Analógico. Fuera de equipos de rack, es realmente difícil encontrar delays digitales que no acaben sonando demasiado delgados, afilados e, incluso demasiado hi-fi y poco musicales.
Después de horas y horas en la web, comparando distintos tipos de delays me incline por el "Deep Blue Delay de Mad Professor", lo que llamo mi atención y la parte intrigante de este equipo es que el Deep Blue es en realidad un pedal digital, aunque la ruta de señal directa es analógica. Por lo que he llegado a entender, es que la parte digital corresponde a la circuitería que gestiona las repeticiones, mientras que todo el entorno (previo y post) sería analógico. Un pedal de retardo de sonido muy limpio, y con unos decays de los ecos muy naturales, exactamente lo que estaba buscando, (en hora buena), Las repeticiones se desvanecen de una forma muy natural. Algo que no es siempre fácil de encontrar en los Delays, No tiene Tap Tempo, ni ninguna otra forma de establecer un tiempo determinado, ni divisores ni subdivisores, ni todas esas cosas tan habituales, nada que ver con las toneladas de diferentes tipos de demora que ofrecen los equipos digitales.
El pedal de retardo de Mad Professor originalmente cuenta con tres controles: "LEVEL", "DELAY" y "REPEAT", PERO en el caso del mio, un control adicional de volumen. Ahora bien, veamos como funcionan cada uno de ellos:
"LEVEL", sirve para controlar la mezcla efecto/señal directa y la cantidad de efecto de retardo, en mi opinion hay que gestionar bien este control para que el sonido no sea excesivamente puro pero, por lo menos permite elegir la cantidad exacta de efecto a nuestro gusto.
"DELAY", ofrece un barrido de tiempos de retardo desde 25 mili-segundos hasta 450 mili-segundos
"REPEAT", este control de "MEZCLA" es exactamente lo que usted imagina que es, y se ejecuta desde una única regeneración hasta una retroalimentación infinita, jugando con estos dos últimos a medida que aumentamos el control "Delay", y controlando bien el "Repeat", la sensación que se obtiene es estar en una actuación en vivo, donde el sonido del escenario está rebotando en las paredes. ¿A tempo?, seguramente no y, por eso suena tan natural.
"VOLUMEN", puesto ahi para tener un mejor control sobre el ciclo de retroalimentación, también sirve como Booster, y aparte de eso le da una gran vida y cuerpo al instrumento.
Uno de los argumentos de venta que ofrece esta marca, es que funciona de muy bien con distorsiones/sobremarchas bien sea por el input o el loop de efectos, de cualquier amplificador. ¿Lo hace?. ¡les aseguro que!, ¡Sí!. Este es uno de los problemas típicos que me he encontrado, básicamente con analógicos, que llegan a saturar el sonido, de tal manera que cualquiera se perdería en la mezcla, pero este funciona de lo mas normal con distorsiones y sobremarchas, garantizado!
Ahora bien, estudiemos un poco este circuito.
Este equipo de retardo esta basado en el circuito integrado PT2399, y su etapa de potencia usa un amplificador operacional OP275 oAD712 , les comento de estos ultimos probé varios integrados incluyendo el OP275, TL072, Tl062. JRC4558, Jrc4559 y NE5532, siento este ultimo el que mas me gusto de todos, a mi parecer le da mas carácter al sonido.
El dia que lo hice sonar por primera vez lo primero que me vino a la mente fue, ¡ESTA VIVO!, "Jose has llegado a tu destino!", esto es sencillamente lo que andaba buscando, es un pedal que hace una sola cosa ¡LA QUE QUIERO! y vaya que la hace muy bien". Evidentemente, tiene muchas más posibilidades pero, para el uso que lo quiero trabaja perfectamente bien, como les había comentado sin tap tempo, sin divisiones, ni otras cosas. Suena musical y muy natural.
¿Es el mejor Delay?. No creo. Pero, es muy bueno, y a partir de hoy va fijo en mi pedalera.
Acá les dejo una muestra de como suena y si alguno de ustedes se interesa por este mundo con muchísimo gusto los ayudo en todo lo que este a mi alcance.

Hello Hello friends, lovers of music and DIY, today I will talk about a project I had in mind for a while, and a few days ago I set out to develop it, and today with a lot of taste and humility I show you! , it is a delay unit in the pure Tape Delay style, that is, the typical Tape Delay (Echoplex and similar). There are two factors that made me go backwards in a tape delay. First, its huge size (come on, as if to integrate the pedal on the pedalboard!), The components are almost impossible to get in my country, (Venezuela) and buy it ?, or play after seeing its exorbitant price. Only the recreation of an authentic analog tape delay that Fulltone sells is already like having to sell a kidney, so imagine what an authentic Echoplex unit or similar should cost. So I got down to work and decided to look for some scheme to build and try to recreate that sound of the mentioned delay, in my search I opted for a digital one but with an analogous answer, but (the blessed "but"), the digital world delays is limited by the number of bits with which the signal is processed and the quality of the Analog / Digital and Digital / Analog converters. Outside of rack equipment, it's really hard to find digital delays that do not end up sounding too thin, sharp and, even too hi-fi and unmusical.
After hours and hours on the web, comparing different types of delays I inclined to the "Deep Blue Delay of Mad Professor", what I call my attention and the intriguing part of this team is that the Deep Blue is actually a digital pedal , although the direct signal path is analog. From what I have come to understand, is that the digital part corresponds to the circuitry that manages the repetitions, while the whole environment (before and after) would be analog. A very clean delay sound pedal, and with a few decays of very natural echoes, exactly what I was looking for, (in good time), The repetitions vanish in a very natural way. Something that is not always easy to find in the Delays, has no Tap Tempo, or any other way to establish a certain time, or dividers or subdivisors, nor all those usual things, nothing to do with the tons of different types of delay that offer digital equipment.
:
"LEVEL", serves to control the direct effect / signal mix and the amount of delay effect, in my opinion you have to manage this control well so that the sound is not excessively pure but, at least it allows you to choose the exact amount of effect to your likingThe pedal Mad Professor's retardation originally has three controls: "LEVEL", "DELAY" and "REPEAT", BUT in the case of mine, an additional volume control. Now, let's see how each of them works.
"DELAY", offers a sweep of delay times from 25 milli-seconds to 450 milli-seconds
"REPEAT", this control of "MIX" is exactly what you imagine it is, and runs from a single regeneration to an infinite feedback, playing with these last two as we increase the control "Delay", and controlling well the "Repeat", The sensation that you get is to be in a live performance, where the sound of the stage is bouncing off the walls. At tempo ?, surely not and, that's why it sounds so naturall.
"VOLUMEN", put there to have a better control over the feedback loop, it also serves as a booster, and apart from that it gives a great life and body to the instrument.
One of the sales arguments offered by this brand, is that it works very well with distortions / overdrives either through the input or the effects loop of any amplifier. Does it ?. I assure you, yes! This is one of the typical problems that I have encountered, basically with analog, that saturate the sound, so that anyone would be lost in the mix, but this works as normal with distortions and overdrive, guaranteed!
Now, let's study this circuit a bit.
This delay equipment is based on the integrated circuit PT2399, and its power stage uses an operational amplifier OP275 or AD712, I told you about these last ones I tried several integrated ones including the OP275, TL072, Tl062. JRC4558, Jrc4559 and NE5532, I feel this last one that I liked most of all, in my opinion it gives more character to the sound.
The day I made it sound for the first time the first thing that came to mind was, THIS IS ALIVE !, "Jose you have reached your destination!", This is simply what I was looking for, it is a pedal that does only one thing THE ONE I WANT! and it goes well. "Obviously, it has many more possibilities but, for the use I want it works perfectly well, as I had told you without tap tempo, without divisions, or other things..
Is it the best Delay?. I don `t believe. But, it is very good, and from today it is fixed on my pedalboard.
Here I leave a sample of how it sounds and if any of you are interested in this world with great pleasure I help them in everything that is within my reach.
