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.
Here's an older design from Catalinbread, but an interesting design as usual. It's a preamp/boost with a wide range of tone shaping capabilities. Schematic can be found here.
Thank you so much! Today I was considering to do my own layout (which is always a pain for me), because I wanted to build this for years now. Quality layout as usual by you. Weekend project: check. :D
i,ve build the pcb version, and it works at the first time!!! as you wrote it,s impotant to use a dual log pot, i buildt mine with a linear one, so the working spot of the pot is not really ok. if you use a log one it would be perfect!!!
(i think you can mark this as verified) greetings from austria bluesanderl
If i was going to guess... since it just kinda connects the legs of the pot... it may just be any value you find works well - i'd wager it's for smoothing out the resistance of the pot. I'd get a second opinion though
Love this booster. It's really a swiss knife. I can custom taylor your freq. response by either boosting or cutting a certain freq. and still be able to boost the output a lot.
Having this pedal first in the chain makes every other effects in the chain so versatile, I just love it. Oh, and it works really, really well with the bjf fuzz 109 after it.Yeah, I have very articulated fuzz sounds with the fuzz pedal being driven by the varioboost.

ReplyDeleteAgreed... this looks like a great project! Thanks!
ReplyDeleteI have some B100K dual-gang pots, so I'll just give it a shot with that.
wow!
ReplyDeletegreat. a parametriq mid boost!
i also have a couple of B100 dual pots, and i will try to build this tonight!
thanks for another great layout!
Congratulation to your work!!!

Works for me. Thanks for the verify!
DeleteThanks for the warning, Bluesanderl. I'll hold off building with the linear pot and source the real deal. I want this pedal to be just right!
DeleteI just need to add:
DeleteDavid... using your layouts, my projects have never looked so good. Thanks! I don't think we can say that enough here.
Aw, thank man! Much appreciated :)
DeleteAs the schematic poped up for this I put on a 100k dual log pot in my tayda order list. Thx for verifying! :)
ReplyDeleteSorry for the noob question, what is the "RX" resistor?
ReplyDeleteIf i was going to guess... since it just kinda connects the legs of the pot... it may just be any value you find works well - i'd wager it's for smoothing out the resistance of the pot. I'd get a second opinion though
ReplyDeleteIn the FSB board discussion, they indicate that the resistor is optional. Not used if you go with the standard build.
DeleteTHanks a lot! Works like a charm :)

ReplyDeleteHi !!
ReplyDeletemust make mine ...
Thanks so much ! :)

ReplyDeletealmost no boosting even in maximum position of gain and 12db... freq works well. any ideas?
ReplyDeleteverry good
