My DS-1 Mods ... with sound clip.

[blustrat]

In my pedal i used common ceramic caps instead of micas, the sound doesn't seem so bad.
Bye.

Cool!

I've now just finished my biggest weekend of fooling and the DS-1 was probably the most noticeable. I'm using it with a Marlique Deluxe (Twin H/B) into a Fender Hot Rod Deluxe. I can get the most awesome sounds out of this rig now.

Just out of interest :

I've sold quite a few DS1/SD1/BD2/TS9's with various improvements for the last three years
I've just got a new "batch" of DS1's in for "upgrading" and use similar tweaks with a few
specific changes.
Comparing to a new "unchanged" one is something that I do a lot, and these kind of changes
including using either LED's or 1N4001's for diodes, produce an overall output level of around
twice the volume of an unmodded one !!
This is with tone/vol/gain all at 12 o'clock and using an A/B box to route to them rather than
in series ( though that is probably just as good )
Not only does this mean that it will "kick" an amp quite nice, also you can keep the levels down
and still be as "loud" as a stock pedal and the noise floor seems better also because of this.

Good stuff

MM.

Hey Melanhead, I did your mods to my DS-1. I must say it is a completely different pedal now. It actually is a lot more versatile and the tone (while still having to dial in a sweet spot) is much better.

Cool, Glad you like it!  I still have another one sitting around in pieces! ... just haven't had a minute to mod it ... or do anything else for that matter ... haven't built anything in months!

Another thing you might like to try (I like it) is to change the output buffer to TS808 style
by changing R22 to 100ohm.

Has anybody tried this mod? What will this mod change?

[vanhansen]

Not a clue what the buffer mod does but I'm about to dig in to my DS-1 again for some more tweaking.    Just as soon as I put a new tip in my iron.

I wasnt sure this thing could ever sound good. I thought of modding it like spraying flowery perfume on a turd.

Pretty much! 

It can be made to sound better than stock but it's not my distortion of choice ....

[vanhansen]

I started digging around in my DS-1 last night.  I've been wanting to try other diode combos for a while.  It's got one 1N4001 and one 1N4148 Si (stock type) now.  I also changed R13 back to 4.7k.  Now, I just need to work on getting rid of the mid scoop that happens and the slight volume drop when hitting a chord.  I think too much bass is getting through.  Any idea on how the mids can be increased?

[Melanhead]

I think by lowering R16, IIRC

I'll try that.  Thanks.  I've got a couple other changes to make too so I'll do that as well and see what happens.

Try this for clippers.

Hey,

I'm new here, I've just made a booster and an overdrive pedal.
But I'd like that pdf of the keeley mod, I've spend the last half hour searching on the net, but I can't seem to find it.
Does anyone have the link? Because it would make things a lot easier for me, I haven't had much experience reading these schematics.
