Colorsound Overdriver tweaked...

[Oliver]

Hello,

a short Time ago i build the Colorsound Overdriver.
I used it as a clean Boost and love the Setting, that it distorts when you hit the GuitarStrings and fades out clean...
But i was unsatisfied with the GainControl, that is too choppy...
I mean, that even 85% there is only a little Boost added and at the last 15% it breaks out into a Chainsaw Fuzz.

In my first Version i only had a 47pF Cap for the second Tranny, that was the first thing i changed to the Stock (200pF).
Than i changed the 6,8K Resistor form the first Tranny's Emitter to Ground by a 10K.
The Result:
At Gain setting all down, there is already a distorting Sound, but only slightly overdriving (not bad).
The Gain raises step by step, when turned up and ends at a good sounding Distortion with a bit FuzzCharakter.

Oh man, i like it now !!!!


bye

wow Oliver - sounds cool. I'll try this & let you know what happens.

I recently had custody of a friend-of-a-friend's orange-coloured Colorsound Power Boost reissue (bass/treble/gain but no volume control) and i LOVED it so much - didn't want to part with it when I had to give it back!

i made one recently (http://web.archive.org/web/20070901230914/homepage.ntlworld.com/s.castledine/greenfuz/over_lyt.html) with silver BC109's and it's every bit as wonderful, all but for that weird gain stage a the end of the rotation which is a normal part of the original & all that. and as other people have said in other threads, switching the BC109's with other usual-suspects transistors has almost no difference on the tone, to my ears anyway.

has to be one of the most underrated builds of all time!
