Keeley mods (wounds) self-inflicted (ds-1)!!!!

arling115 · February 28, 2006, 07:59:54 PM

Using what I was told is what ships from the factory when you buy a ds-1 from keeley, I modded my ds-1. Its really a huge improvement, and the best thing is it's quiet like a ten year old in a catholic school with a nun armed with a ruler hanging over him (of course that kids still gonna get a little loud when the nuns out of the room or hes excited (high gain))

Costed me 12 bucks, under a weeks wait and about two and a half hours soldering. You can't see any of the mods, it looks stock b/c I didn't want to drill the hole in it. I have enough trouble getting the indicator LED in it's hole.

If I can find one, I'm gonna use a clear plastic caseto house it. It's regular housing is a bit small, for all the new parts (circuit board had to bend a little bit to fit in).

I'd also like to replace the current indicator LED w/ a brighter 5mm one. Is all I have to do swap the two?

Thanks for anyone that helped. It sounds better. Much better. and It works twice as well as a booster to my Carvin Tone navigator.

YIPPE.

(Clips come soon)

It is one of the more pleasant surprises I've come across. After having a DS-1 for several years and it sitting in the box, I traded it off before getting in to DIY. Good thing they're cheap. My new one was stock for less than 12 hours after I bought it. It like it much better now. Gonna play around with the diode arrangement though. It sounds good through my Marshall but it could be better.

If using 5mm status LED change R35 to 2.4k 1/4W 1% Metal Film

That's what keep us going ... If we had nothing to tweak what would we do

Sit on our tush twiddling our thumbs, or play more guitar.

Last night I swapped the red LED in D4 for the stock Si diode. It's sounds better than with 2 LEDs. I wanted to put a 1N4001 in there but the legs of the 4001 are too fat and I'm not about to drill out the PCB hole. I'll probably solder some thinner legs on to one at some point but it was getting late and I was getting tired.

Headbuttking2: the Keeley mods are here. Melanhead started with those and tweaked some values here and there to his taste. He did a good job too.

Ultra mod:

*use switch for on-the-fly changing

The mods on the other page are as I'm told outdated or a different version. I was told these are what ships from him.
It sounds awesome. I'd also like to pit it against those other mods to A/B it if I can.

vanhansen · March 02, 2006, 09:15:57 AM

Good stuff. How does it compare to his older mods and what Melanhead did?

arling115 · March 02, 2006, 04:48:16 PM

I've never heard or used another modded ds-1 in person. So I can't really make that comparison.

vanhansen · March 02, 2006, 11:09:05 PM

No problem. I went in tonight and made some more changes. Namely C9 to 1uf and C11 to 0.033uf and R14 to 1.5k. It sounded better to me but then I remember putting the stock Si diode back in D4. Well, that got changed back to a red 3mm LED. There's what I was looking for. Now I have a combo of Melanhead's mods and 2 versions of Keeley's (if the ones above are shipped from him) plus my own itty bitty diode tweak.

This thing kicks some serious @ss now.

I don't know about the Keely mod, but Monte Allums's Tri-gain Recto Mod (http://www.monteallums.com/Product_links.html#DS1DRectifier) is beyond awesome. And it's got 3 different selectable gain stages. Sweet! I did it as my first pedal mod.
