who has a Redeemer Circuit in their bass?

Sign in to disble this ad
I just listened to a soundclip of a TBer's new Skjold "passive" bass with this circuit installed. It sounded real lively and "wet". Does anyone else out there have experience with this? Does it do what it claims? I can't seem to find a whole lot by doing a search.

It is a very cool circuit . It does do what it claims . I was able to a/b it at a guitar show with one of my basses in passive mode . Actively it did very little because the preamp already balances the impedance but passively it made a huge difference . It basically made it sound like it did with my normal preamp engaged but set flat .

Highly recommend it ,

Pete

It is not proprietary . It is made by Creations Audio Labs . The circuit is called the redeemer .

OK, even after reading the website:
http://www.creationaudiolabs.com/redeemer.html
and the fluffy review:
http://musicianshotline.com/pdf/gear...bsRedeemer.pdf
I still don't know what this thing is. They seem to be saying it can be used as a preamp, or in addition to a preamp. They say it can drive the line input of a mixer, yet it is still compatible with guitar amp inputs. How hot is this signal- is it just the same output level as the instrument had previously, but at a lower output impedance? The review describes the noise level as "not nearly as high as other battery operated devices", and then they describe it as "within acceptable limits". What if you add it to an existing preamp, does it amplify the existing noise as well as adding a bit of its own "acceptable" noise? Is this just an impedance-changing device, or is there more to it?

Sorry, I know I should ask the manufacturer these questions, but I frankly don't trust any manufacturer to tell the truth about noise. Especially preamp manufacturers.

this might be the answer to the buffer issues in another thread...

I'd suggest trying the Q-Tuners passive before installing active electronics. Let us know how it works out!

So I guess the jury is out on this? Pete Skjold ( nice work by the way ) describes this as an "active" sound without the eq. Looking at the installation instructions, It's downstream of everything in the guitar cavity. So could this be some sort of euivalent to a Sonic Maximizer or such? I hear people describing those as "cleaning up the sound". Still not sure what this thing is, or does, but it has my attention.

In a nutshell it restores the signal back to its original impedance which is effected by the cord and inputs and circriutry of the other devices which drain signal and lower the output . It does not add gain to the original signal .

Call the manufacturer , they are great guys to deal with .

If it's what I think it is, it's a unity gain Op-Amp being used to drive the line to the stack/whatever. It's providing an ideal load for the pickups.

Bloody expensive though for a simple IC and battery clip...

and another thought... imagine having to remove your pickguard to replace a battery mid gig... I hope it's only on when the jack is inserted into the socket... mind you, I'd have to remember to unplug every time as I normally leave mine all connected up ready to noodle with.

I'm hoping it's not a cheap opamp, but something better than that. From my limited testing, I've only found one opamp that didn't compromise the tone in an undesirable way (LM4562), and it requires over 10 ma. Maybe someone will take one apart and see.....

Hmmm, I'm no tech-guru, but it does appear to be a simple 9v op-amp buffer. I think manicbassman has got it right.

I suppose if you had been running a passive bass through a super long cable, or too many unbuffered effects - then this would be a problem solver. The thing is, you can already achieve this with a lot of quality preamps (onboard & external) and buffers already on the market that achieve the same thing with more features at less cost!

On the other hand, if you're a psuedo-purist, you get an active bass without all the knobs.

As always, I should reserve my judgement until I actually try one.

If I ever come across one.

Which would surprise me.

So what is the benefit of the "active" bass without the EQ? Is the tone somehow enhanced vs full passive mode?

That's the claim they make. Some people like a crispy clear "active" sound, and maybe they want to add that sound to an existing passive bass without adding any EQ or volume boost.

I just noticed that "Creation Audio Labs" isn't too far from where I live.
Maybe I actually will bump into someone who has one!

Did you also note their $225 boost pedal? This stuff must be pretty incredible seeing as how I got my Xotic RC Booster for less than $200 (including input gain control & high and low shelving eq). Creation's pedal does look pretty sharp though, and I am a sucker for boutique gear......

Yes. I'll be giving it a go once I pay off some of my other recent pruchases. Let us all know how it turns out when yours arrives...
