Hi everyone. Since i bought fulltone's fulldrive 2 i've really been need more bass tone. I decide to do mod to bring bass tone back. And share is with you.  Here we are...

Here is the circuit

First and last you need to do is change 0.1 uf cap to 0.22 uf (or more, read to the end). My is marked is Tracon  2A104K.

Here is the result. As you can see i used polarized cap, it's because i'd not usual one.

You can change cap with even more capacitance and bring more bass. Here is cap - freq data

0.1uF - 339 Hz
0.22uF - 154 Hz
0.47uF - 72 Hz


I also changed a transistors to Germanium in experimental purposes. And they sound great !  Good Luck. Sorry for my bad english )

If you are not believe in yourself DO NOT do anything above.
