Hi!
I made this one ysterday. i used the eagle files from http://gaussmarkov.net/wordpress/circuits/ubescreamer/ just modified with groundpour and relocated IN and OUT pads.
my problem is that it has very weak output, i need to max the ubescreamer volume and 3/4 full of my amp's (60watts) volume just to have the "bedroom volume"
already tried different ICs just to be sure, resolder all the joints and reched the wires.and rechecked for solder joints and also run a cutter between tracks and joints just to be sure ;)
this seems to really have low volume :'(
TIA
anybody? :icon_redface:
Got some voltage readings? or maybe a pic of the board? Preferably both, there's not much anyone can do without that kinda stuff
Would you say that aside from the output level, the circuit is behaving itself? dist., tone, mixing of clean with dist??
If so you can at least isolate the issue to somewhere in the last stage.
The first thing i'd check is the 100k pot at the tail end of the circuit, make sure you're not sending the signal to ground
Then i'd probably check the components in the last inverter stage, make sure you're getting enough gain
btw i'm far from an expert. I finished my Ube today and it has HEAPS of output, regardless of drive and tone settings

good luck
