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.
Got a little simple boost/preamp for your Thursday. Should be a pretty easy fit in a 1590A. J113 alternatives would be J201, 2N5457, and probably a couple other JFETs that are obsolete. 😑
Built it, definitely works and gives plenty of volume boost, however with 2N5458s, it did sound pretty muddy like Marcus Corradini said. Did not sound actually muddy the way a fuzz does, but sounded like the transistor was pretty misbiased. Swapped out for a J201 and sounds way better with more clarity.
Verified! I used J113. The tone is a little muddy...
ReplyDeleteVerified! With J201 sounds very good
ReplyDeleteIt can work in bass?
ReplyDeleteIt should. You may want to up the value of the 47nf cap though.
