Keeley mods, whats your thoughts?

Try the search feature this topic has been brought up in the past. Not sure if he does use the modded dd3. He has used the compressor in the studio in the past.

I didn't know he had one. I know he had tried a Java Boost, and the Fuzz but liked the compressor best of Keeley pedals. I have a moded TS9 of Keeley's but I'm not a good judge of pedals. My guitars are wall decoration.

If the article says his DD3 is a Keeley mod than it must be.

Since Keeley is a neibor of mine I know the company to be very will to do what it takes to make you happy. Call them you never know when Robert will answer the phone. You can have them purchase the pedal here and send it modded.

It is worth it.  It makes a really good sounding pedal GREAT!  And the work is done fast, so you aren't waiting very long.  It really added some balls to the bottom end.

I've modded a ton of pedals over the years, some good some a waste of time.
Keeley makes good pedals but keep in mind, not only will modded and unmodded pedals sound a little different from one pedal to the next, the overall tone and benefit from the mod will differ from one amp to the next. A modded pedal that sounds great in your marshall may sound like total crap in your fender or boogie, etc.. and vice versa.
If you've got a dd-2 and dd-3 then you've got the best of both worlds because they changed the processing chip in 73 which is why the dd-3 has more of a digital sound to it, but works nicely on a number of amps because the delays stay cleaner and a little more prominent. That works well in higher gain situations.
I've found that mods work best on some overdrive pedals. On pedals like delay I just can't justify the cost when they're just changing a few values on the pedal. It won't make a digital pedal into an analog pedal regardless of what anyone tells you.

A guy named Monte Allums( I think that's how you spell it) also has mods that are basically like Keeley's and then go a step further in some cases.
Keep in mind that all these guys do basically the same thing for their mods, just substituting a value here and there.
If you're careful and decent with a low wattage soldering iron it's pretty easy to do your own mods. The schematics are everywhere and once you've done a couple you can understand exactly what those guys are doing.
I still do mods but guys like Joe prove that if you have good amps and know what you're doing mods aren't the magic formula a lot of players like to believe they are.

Keeley TS-9  - great flexible pedal.

Beerdog80 is right. The BD-2 sounds much better modded and it's one of the most common mods.
If you're going to mod that pedal though I'd go for the H2O mod over the Keeley.
Both mods are done by upgrading a number of components on the board but the H2O version gives you more flexibility. I've done both to the BD-2 and much prefer the Allums mod for this particular pedal.
This is one of those day and night mods though. There's a big difference after the upgrade.

The Allums mod is good too.  I've installed a few of his kits in BD-2's and they sounded great.  Really smooth. In most cases, ANY mod on this pedal will make it sound much better than stock.

I've got a keeley compressor and one of his modded Ibanez analog delays and used to have a modded Ts9. All are improvements on the originals.

...but only, or course, to the ears of a guitarist.

I did an experiment once by a/b-ing the keeley ts9 with the stock reissue. My wife swore they sounded identical. After ten minutes I was almost weeping with frustration at her failure to appreciate the vast tonal superiority of the keeley mod.
