Hey Guys,

I own a couple different boost/overdrive pedals and I wanted to try this latest version of the Timmy pedal from all the hype I've read about. It did sound pretty darn good however I wanted a tighter bass response and the pedal to have more bass cut not only when for when I'm boosting but when I'm running running the drive knob at higher settings - into my cleaner amps not the have the pedal mush out, kind of like how the SD-1 or OD-9 pedals cut the bass. I found my pedal could maybe get half that amount of cut I was looking for. I wanted the bass knob on the Timmy to have more range and to be more usable with my high gain amps. I went looking for a solution as I figured I wasn't the only one with this problem so after a little research and looking at schematics of my other favorite pedals and comparing it to the Timmy to give me some ideas. I thought the simplest thing I could do is try lowering the first input capacitor C2 from my pedal of 39n or .039uf (on most of the Timmy schematics it calls out for .047uf) and trying various caps from .022uf, .0022uf and finally .001uf. I found the more I went down the cleaner and sharper and tighter the attack was and the pedal didn't sound as muddy and the more usable the bass knob was perfect for high gain and boosting where you want the pedal to have a little more cut. I personally like the .001uf, however even with the bass knob set at no cut the pedal still will cut some bass when turn on.

After doing this it is now kicking the OD-9 off the board as it sounds perfect for my setup.

Rock on,
Jason

This is cool stuff. I have the first version Timmy with the bread board and it is a lot tighter then the newer versions.

I know you and another forum member has said that and for the life of me can’t understand why that is looking at the revs throughout the years. My new timmy stock is a loose sounding pedal.

A few years ago I got a new Timmy since I needed another for something different... I wanted to have a few with different opamps for more versatility. The second I plugged into it, I thought something was wrong with it. I checked everything. There seems to be something in the design that makes the new Timmy mushy and blurry. I couldn’t get rid of it quick enough.

FWIW, I bought both my Tim and Timmy new (both with the bread board) back in 2007 or 2008. Over the years I have tried many different opamps, but seem to always come back to the stock 4559.
 
Based on that diagram, I would play around with C5 instead of C2. That is the typical cap that people modify to change the amount of bass cut in Tubescreamer type pedals.

I concur. I bought a current model as well, and couldn't sell it fast enough. Total turd.
