I have been wanting to do this for decades.... Make a pedal that has the Rockman Distortion sound. The chorus and echo would be other pedals.

I would like to collaborate with those willing to on this forum in creating a circuit that can be used in a pedal format.

The compression and fixed EQ sections seem to have the greatest influence on how 'that' sound is produced. The pedal version would have controls for gain, level and perhaps some EQ tweaking control. A foot switch for Edge / Dist...

Hi folks ,last week i trace ,a spark booster mini from a friend of mine.just only for learn how is work.
i triple check de values and the schematics.minus the switching system ,is very complicated, and we can put instead , a 3p3t switch.

This is the wrong Helios schematic where all came from:

Here is the proof of my theory (scroll down):

After showing you a couple of not-clones, here's a more original circuit I'm proud of. It's a parametric mid frequency eq with also bass and treble controls.
I think equalizers are very very powerful effects, altough they shouldn't be overestimated when post production is an option. Usually diy-ing a graphic eq is hindered by the amount of controls needed for a decent amount of bands, being them pots or worse, sliders. So I wanted to look for an alternative, and one which didn't feel like a...

Very nice midboost, i am planning to build it in a stompbox.

I've always liked the tone benders, and thought that it would be fun to build a few with differing component choices and various transistors. Over the last few months, I've made about twenty of the things - all slightly different. I've extensively played through them, and have chosen the two or three that sound best (to my ears). The very best is shown here - it's a smoothed silicon bender, and just sounds great! All the other prototypes were put into diecast boxes and given to musician friends...
