Oakley SRE330

Post by Spoontex » Fri Apr 10, 2020 3:56 pm

Hello,

I’m searching a clone of the Roland SDD 320. And searching I found the Oakley SRE 330. This is a good candidate for my studio?

Thanks

The Oakley SRE-330 is definitely a good candidate for your studio as a fine sounding analogue chorus unit full stop, though I'm not sure how closely it can emulate the Roland SDD-320 Dimension D if that's an absolute must. I've never owned a D so can't say if it gets close enough. I liked the Oakley demos so much I bought the kit but it's still waiting to be built.

I also have a Roland SDX-330 Dimensional Expander, which although digital, claims to do a very close emulation of the D in one of its preset algorithms and generally sounds great. It would be nice to report a comparison with the Oakley, which when built, I'm hoping as an analogue device, will have an edge on the SDX-330.

The much sought after SDX-330 is a bit hard to find at a decent price these days and some will claim it's still not as close to the 'legendary' D as Roland would have it. Another Roland candidate that's often overlooked in this area is the RSP-550.

Finally, all these other units are not such a narrow-band specialist as the D and will outstrip it in versatility.

The SRE330 can get you close but it won't do it exactly straight out of the box. The SDD320 features several interesting and unique aspects. Firstly, the chorus effect does not affect the bass end of the audio spectrum, Secondly, it uses a stereo widening process by which the mono parts of the signal are attenuated.

Both these aspects can be simulated externally using a decent mixing desk with EQ and stereo widening features when used with the SRE330. Any DAW based mixer, Cubase, Live et al, can certainly do it. So to make the SRE330 behave similarly to the SDD320 you will need to use external processing, firstly to high pass filter the audio going to the SRE330, secondly to widen the output, and thirdly to control the wet/dry signal.

That said, I had a SDD320 and much preferred the sound of the SRE330 for the things I was using it for.

Klark Teknik will be making a clone of the SDD320 sometime this year.

And Roland have their Boss DC-2W which is pretty neat:

For DIY Juergen Haible's Subtle Chorus is about as close as you can get:

Thanks for the the answers.

I study all this options. But I think I go fot the SRE330 or maybe the Subtle Chorus.

Basically I want an analog chorus unit, for "everything", guitars, basses, voices, mixes...

What do you think about?

Thanks.

what about modified BOSS CE-300 (for analogue line level signal) ? I own one i modified years ago to be similar to SDD320 and it is amazingly good

This is a good idea. I will keep it in mind.

The expected price on the upcoming KT BBD-320 is 149Euros. There is little chance anyone could make it cheaper than that. I was thinking about doing my own version of the SDD-320 at some point, but I shan't bother now. That said, Music Group have been touting a lot of new toys recently and not all of them have made it to market.

Modifying a CE-300 is possible but to get that real SDD-320 experience you'll need to hack it quite a bit. The LF roll off for the BBD pathway and the subtle stereo widening are part of what makes the SDD-320 so unique.

Yes, I saw the KT BBD-320! and the price is amazing. What you think about the Berhinger Klark products? It worth? It's "straight" replica? Any one has the opportunity to examine one of the Klark products?

Thanks.

I am not sure if this is the right place to discuss this product as it seems to be not really closely related to the SRE 330 - there is already a topic about it here: viewtopic.php?t=226555

I may well buy one to see what's up. And also to see if I can sneak a few modifications in there too.

What is KT's stuff like these days? I've no idea. They used to be excellently made, but with Music Group's buying power and Far Eastern manufacturing it's no surprise that they can make stuff a lot cheaper than anyone else - including those of us building at home.

I had Behringer's CC300 Dim-C clone pedal and it was pretty good (especially because it was only 25GBP). They made a few mistakes in their version but this was relatively easy to rectify. Even as stock it was an excellent purchase.

Hi Tony, Hi wigglers !
I just finished my SRE330, but the fuses blow a way each time I put the unit on. Must have a short circuit somewhere, but don’t know where to begin with !
I use the Yamaha PA-20.
My first idea is about the 2 TO-220 : I didn’t isolated them with the bushes as I didn’t buy them. Is it a possible cause of this issue?
BTW, here are a few pictures of the face (waiting the knobs !)

Thanks for help

Yes. It is essential that both bushes and insulating pads be used for the TO-220 devices. No part of the metal tab on either TO-220 device should make electrical contact with the metal case. Use a multimeter to check that the resistance between each tab and the case is not below 100 ohms.

Hi Tony,

OK it works after isolating the 2 TO-220, the fuses won’t blow up anymore.

The relay clicks when put on and off.

But none of the LED light on (either the power LED or the Peak LEDs). I paid attention to have them oriented the right way.

I have +15v and -15v where expected.

Here are pictures of the stripboards where the LEDs are mounted on, if it can help.

Update : I decided to make a bridge on the 2 stripboards, and now it works ! The peak LEDs and the power LED light as expected !

Time to calibrate ! 😎
