Orange squeezer build report and pics

[LivingDeadPunk]

I had built a lofomofo and a Rangemaster for a friend before and this was actually my first personnal pedal.






I used Tonepad layout and it worked first time I fired it up, after reading Tonepad build reports I decided to use these mods:


Input cap: 0.015 Uf instead of 0.047Uf

Output cap: 1uf film instead of 4.7Uf electro  

IC: OPA2134 instead of 4558

Poping problem, add resistors between output and ground.

The sound is just brilliant, a bluesy compression with a soft overdrive when you crank the volume up.

great work!

Wow!  Nice finish.  I particularly like the "orange peel" effect as the background   The inside looks really neat too.

On a related note, does anybody have any ideas on how to create an attack or compression amount control on an OS?

Great Build BTW!

If you do a search for OS+++ there is a thread accompanying the layout.

I did a PCB layout for an OS that has compression and attack controls. Mods are by Mark et al. If you build it please post a build report.

Am I the only one that doesn't see any pics? Not even red X's, just nothing...  :?

That's a really high quality OP you've chosen. Did you try with the original 4558 and weren't satisfied? Do you have an opinion on how much better it gets?

Looks great.  

I've got a vero build in progress, board is done and I just need to drill and finish the enclosure and box it up.  Hope it looks as good as your when it's done.   :wink:

That's a great design! I'm a fan of the orange peel you went with. There are a lot of creative people in this forum, for sure.

Hi,

Yes I tried the 4558 and I found it to be quite noisy. It's hard to quantify the improvement apart from the noise level, I can't explain why but I definitely prefer the sound of the OPA2134, it's just the sound I was after.

Hi LDP

Looks very good.

I am building one at the moment and after your description of the sound it's just what I'm after.

I hadn't thought of experimenting with the Opamp, but now I definitly will.

I was planning to use the orange peel look as well, when it's finished, nice off you to make a prototype ( ) so I can see what it looks like.

Regards

Carsten
