5 from 5 Fantástico

Un pedal con mucha clase. El germanio el diseño clase A le dan un toque especial. Además es versátil, puedes ajustar dos ganancias y dos volúmenes y tener dos sonidos a golpe de pie, desde un limpio calentito hasta sonidos fuzzeros. El potenciómetro de EQ tiene una respuesta muy curiosa, da la impresión de que a medida que van entrando graves, entran también más armónicos y sube algo la ganancia. Muy contento con el pedal.

5 from 5 Very versatile OD pedal

The pedal: Duocast is based on the diagram of a recording console preamp from the 60s (at the time some guitarists plugged directly into the console, like The Beatles in Revolution for example). The result is a versatile overdrive that ranges from clean boost to fuzz, with two foot-selectable gain levels and hand-selectable 9 / 24v power supply

The sound: very transparent, all frequencies are amplified equally (flat range), not the medium boost typical of the Tube Screamer for example. Cleans very well with the volume of your guitar too. High output level. Two internal trimpots to adjust the low and high gain in conjecture with the external gain pot. Lo-cut pot to reduce low frequencies. Adjustable output level for each gain. By choosing 24v you get higher headroom..

The build: not for the beginner. Documentation is minimal. Better to have some experience. Some inconsistencies with the parts list. High quality PCB, good point, but some supplied filter capacitors are a bit too big. The supplied transistor socket (I assume for the germanium transistor) does not fit into the PCB holes. I built another one with an IC socket. There is another small PCB provided for a DPDT switch but no schematic for wiring it. It doesnt matter, one can do without it.

I suggest a build order:
1 - mount all the electro-mechanical parts on the box without tightening too much, some of these parts will keep the PCB in place later (pots, 24V switch and leds).
2 - solder the components on the PCB starting from the small parts and ending with the biggest, the transformer.
3 - prepare all the wires (strip the ends and place a small drop of solder on each)
4 - solder the wires between in and out jacks and the bypass switch
5 - solder all the other wires starting from the PCB
6 - install carefully the PCB on the legs of the components that hold it, then solder
7 - solder all the wires coming out of the PCB to their respective destinations.

I love the sound and am happy that such a kit exists. Thank you Musikding !

5 from 5 Great sounding pedal

The pedal sounds great. Versatile.
Easy build if you have some experince, but should probably be not be your first build.
The transistor is tall. Remember to have a tall enclosure.

5 from 5 Formidable

Reproduction du pré ampli Broadcast utilisé par les Stones, les Beatles pour ne citer qu’eux.
Superbe en sons clairs, chaleureux et vivants.
Possibilité d’avoir une fuzz très énervée et organique avec le tone au minimum, allant vers un overdrive vintage lorsqu’on déplace le tone dans le sens horaire.
Le switch permet de mettre le circuit en 9v ou 27v (24v en interne en fait ) pour plus de headroom et des sons clairs plus précis.
Le montage se fait sans difficulté grâce aux composants triés et marqués par Musikding.
Parfait !!!
