This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
Somehow I've not laid out this DIY classic, so here's the BSIAB2. It's a great distortion pedal designed by Ed Guidry and is probably a must for any of you EVH fans.
Don't work. The signal goes through the effect, but the volume and gain are very very low. Bad and low sound ,it's as if part of the signal goes to ground. Ive checked that there aren't bridges, and bad welds. I can't find fault. I have seen that the 1 uf cap next to 220nf in original schematics is non electrolitic, i replace but has not improved. Thanks i will try again ; )
Hola Julio. Ahora mismo estoy con 2 pedales por encargo, pero en terminarlos repaso el esquema y lo monto de nuevo. ( lo he montado 2 veces y nada ) Tengo mucha curiosidad por escuchar como suena esta versión. He contruido 3 o 4 versiones diferentes que andan por internet y tienes sus diferencias y quiero porbar estre xk los montajes de esta web siempre me han dado los mejores resultados. En cuando al BSIAB el montaje de gaussmarkov es el que mejor resultado me ha dado. Si te corre prisa monta ese. Saludos!
Good afternoon Did someone get this layout?I would like to know how to make the Contour mod in this layout? Would you like to put a sample for us? thank you
Work it! Funciona! Por fin los conseguí, creo que estaba utilizando un condensador defectuoso. como siempre muy buena calidad de sonido y muy poco ruido de fondo. Muy recomendable ; )
Excellent, I built a unit using the printed layout, I just needed to use a 220pF capacitor (250) and I used the J201 in all "Q", with electrolytics in 1uF. wonderful project, rich in harmonics, maybe even make the contour mod, but I think it won't even be necessary.
Two quick tips: 1) I found the BSIAB II too dark in its stock form. I removed the two .0022uF caps at the end, and put a .001uF cap on a toggle switch, in place of the next-to-last .0022uF cap. This gives me a 'Normal' and 'Bright' mode (the latter of which I use more often). 2) I've had good results using a 560pF cap in place of the 470pF. This gives a little/slight boost in the mids.
Great Christmas gift! I was expecting for it. I'll try it right now! Tanks man

ReplyDeleteDo you regulated voltage in drain of Q5? It has to be 4.5-5.5v (sorry for me english)
DeleteYes my friend. The voltage not is the problem. I try today again. Tranquilo nacho, hacemos los que podemos con el ingles ; )
ReplyDeleteLograste encontrar el problema???

DeleteHave you solved the "problemo" buddy? I was thinking about to build it

ReplyDeleteHi. Can you verify this. Just finished building it and it works and sounds excellent. Absolutely fine.
ReplyDeleteCool. Thanks for verifying!

Deletethe link shows all the possible options
can i just use all j201s or all 2n5457's i use this interchangebly with no problems also mpf102
ReplyDeleteWork it! Funciona! Por fin los conseguí, creo que estaba utilizando un condensador defectuoso. como siempre muy buena calidad de sonido y muy poco ruido de fondo. Muy recomendable ; )
ReplyDeleteAjustar en preset a 4,5 volts
ReplyDeleteHola, solo tengo j201, podria ponerlos en lugar de los 2n5457?
ReplyDeleteEso debería estar bien.

Built it. Had a problem with volume drop. it because of my bad volume pot, when i replace the pot, the problem was gone.

Definitely in my top 3 dirt pedals of all time.
