Title: OSP TS808
Post by: gtangas on June 09, 2013, 06:10:20 PM
Hi guys

Finish building a MB OSP tube screamer using 1n4148 and for comp bat46

With the 1n4148 I'm having a very low drive... I know that with comp I get more vol and more gain but that is not the issue.

Even the gain pot doesn't change much the low gain that I'm having with the 1n4148 diodes

Anyone can help me?!

Sound like it's not a problem with the diodes...check all your solder joints, audio probe the circuit, see where it's going wrong (probably in the first opamp stage).
