29 Pedals EUNA - baked-in EQ?

#21
What is most likely is the first pedal you were plugged into before you got the Euna was putting a load on your instrument and that had a sound. Then when you got the Euna and put it in the mix you changed what you plug your bass into, how it drives loads, and that also has a sound. Now its just up to you to decide which of those sounds you like most. There isn't any objective good or bad. Believable has likely spent more time designing a buffer pedal than anyone else in history. Even the 'great buffer' in a lot of products is a generic circuit block that performs fine because guitars and basses are not high bandwidth instruments and as long as you go from high impedance to lowish impedance you're probably going to sound fine within a reasonable range of tones.

Is impedance considered a baked in eq or is it actually allowing you to hear frequencies otherwise attenuated by your signal chain.

To me, it’s like saying a wireless system has a baked in EQ over a 50ft cable run (which is a LPF in itself).

Either way, try not to fret too much. If it sounds good and works for you it’s golden.

The euna is about as standard as a buffer circuit as you can get.

I don't know what the input of the caveman looks like but since it's based on a neve there's a good chance you're hitting a transformer first. This has the potential to shift around some of the baked in eq of the caveman

When talking about pedals that adds additional coloration to your tone it is usually not just about EQ.

In case of hitting a transformer it is also likely to add some subtle saturation, which means added harmonic content, as well as compression, which also does actually in the process subtly alter the tonal balance.

And both these factors will interact and react much more dynamically to the input than a simple fixed EQ.

Which is to say you can't replicate all coloration with a simple EQ pedal, it is usually much more complex and dynamic than that.

I'm more of a guitar player than bassist, but I'm in the process of building a little fx board for my bass. I currently have three EUNA's (one on each of my guitar pedalboards, and one for my bass board). I had four of them at one point. I wouldn't build a pedalboard without one.

Care to share why you are so hooked?

Well I had a play with the captures and they do indeed have a nice sparkle, the EQ options are pretty good too. Not the same as the real thing but gives an insight into what the real thing might do.

Thank you !
So the captures show it with added sparkle, too.

I can't say that I understand how all this works and interacts.

Point is ... I am trying to have a signal chain that is as good as possible within my price range. This is why I prefer as few as possible tone-altering circuits. Less circuits, less interactions, better tone.
In the past, the more EQ and "character" and "tone magic" I added, the more I ran into weird interactions and more often than not, the endresult was "lacking". And it was often hard to describe.
So I decided to go simple and good quality, thus the EUNA.

Now ... if the EUNA does more than just keep the signal true and pristine that would be problematic in this concept. Because I can never know in what ways this might mess with the pedals downstream.

Yes. It has a permanent place on my recordng board right after the Input and before the Thumpinator and the Caveman. Every bass just sounds better with it.

Fryette will be releasing their new Valvulator Mini tube buffer/line driver soon. I have the original version on one of my boards, and it's the first time I used a buffer that really wow'ed me. The original was big and heavy though. I will pick up one of the new Mini's when it comes out, but I'm almost secretly hoping that I don't like it better than my EUNA's, as it would be expensive to replace 3 EUNA's.

This is one of my guitar boards that has the OG Valvulator on it. The OG was sold as a VHT unit, but was built by Fryette.

I've been running a Skeptical Buffer from PedalPCB for a year now. It is a clone kit of the EUNA's 'buffha' section without the loop or 'Whatever' power. It has a baked in EQ and sound and is not just a buffer. As we know any pedal that is on becomes a buffer and my tuner does not change the sound of my bass but the Skeptical Buffer does while using a short cable from an active 18V bass. This is not impedance lowering/matching that is happening. There is a pleasant EQ or baked-in sound even with the switches off.
RCO Pedals Skeptical Buffah'
I like the sound it makes but this is a preamp (a unity amplifier w/groovy filter switches for a few nice EQs). It also surely isn't just the 'quality components' because my clones do the same thing a EUNA does. That is not to take away from the build quality of 29 Pedals boxen. I like it but I don't pretend to believe the marketing. I also have a few of the clones for a couple of different projects because I really like the sound.

It will be interesting to see what I think of the EUNA. If I don't feel like it does anything for my passive pbass I'll just move it along. Honestly I'm not even sure I want to add another pedal to the board. But I am looking forward to trying it out!

You have three of them! You must like what they do to your tone!!

This is the point why I started the thread. And despite the knowledge of TB, no definitive answer has surfaced.
Because if the EUNA were just a good buffer with a baked in EQ / sound, that would change some things. It would be treated as a tone sweetener and not a signal improving device.

I've looked as well for more information beyond "It's a buffer" with no luck. I got more information from building a clone. It really is more of a tone sweetener that is being touted as a buffer which I think undersells the device and certainly helped create rancor towards the marketing and cost of "just a buffer".

However, no one seems to share more info on the device most anywhere on the intertubes and when building one out of decent parts my tone sweetened up too. I am to understand that it is named EUNA more or less, sort of kinda after the unity amplifier that it is? However, the company markets it as a buffer instead of a tone sweetener and then gets very close to or crosses over into audiophile marketing in people's minds. That helps many equate that kind of talk with empty hype and silly snake oil.

It's too bad. The EUNA is a really nice sounding device.
