EUNA and OAMP (pronounced yoo-nah and w-amp) are studio quality input and output drivers loaded with switchable true bypass loops to accommodate a wide variety of rigs, pedalboard and studio setups. Both of these pedals can be thought as utility boxes to protect and condition your instruments signal from start to finish, replacing common input and output buffers with high headroom, low-noise circuits and helpful filters and gain stage adjustments. If you’ve experience a duller or weak signal from a mess of long cables, you’ve experienced the side effects of cable capacitance. EUNA, which stands for Elite Unity Amplifier, is a console grade dual-stage driver that focuses on preserving the front end of your signal chain. By using this device instead of a common buffer, the detail and snap of your strings will be restored not to mention enhanced if you choose do use its 3 onboard filters. The Bright and Low switches will add just a touch of low end emphasis to fatten up your pickups or higher frequencies in the same manner as an amplifier's Bright switch. The Harmonics switch boost airy upper frequencies beyond the fundamentals to give any rig some extra sparkle and harmonic overtones.
Each pedal has a similar layout with an input, output and a send and return, this means there is an effects loop that engages when the EUNA or OAMP is bypassed. Some applications would be to place your fuzz (that wants to be first in the chain) in the loop, so when you switch the EUNA off, the fuzz will turn on and respond just like your guitar going direct into the fuzz because it is! You can also treat this as an alternate pedal loop and string together some pedals and activate them all at once with a single stomp.
OAMP has a similar design that preserves the integrity of your signal on the way to your amplifier. Most of the time, this cable run will be longer, whether on stage or in my case a home studio with a 50ft cable run to the amp booth. The OAMP excels in this application as it can push 20dB of clean output and provide a total of 29dB of gain to drive an amp. The input and output stages each have low and high settings in addition to Bright and Dark modes which can be helpful in quite a few scenarios: warming up or attenuating a hot signal chain or brightening up a backline amp that’s overdue for servicing.
Both the EUNA and OAMP feature 29 Pedals’ WHATEVER power supply which allows you to power these pedals with Whatever power you got, specifically 7.5V to 35V and that’s either AC or DC. Whatever, plug it in!

Clicked on this video thinking Andy was gonna demo 29 pedals in less than 14 minutes. Turns out I was mistaken :)
Not entirely
We need more pedals with a whatever power input
There's actually a very, very good reason why we don't and probably shouldn't have more pedals with whatever power input.
Converting, regulating and isolating power take up a fair amount of space in parts and needs proper shielding to not interfere with the signal path.
Having this done on a separate power supply you can huck under your board where it doesn't take up any precious real-estate and can is shielded from giving out rfi by being in its own box.
Putting this task on the pedal really doesn't make sense, when you consider the amount of completely unnecessary parts for converting, regulating, isolating and shielding that are probably what makes these two pedals so big. Obviously just a guess but id be willing to bet these pedals could be made half as big if they omitted this feature which if we're honest is not going to get used by 99% of people since everyone's already using a good isolated power supply.
Andy makin that Fuzz face 🤪
Yep, makes everything sound like a million bucks. And that loop is GOLD! Gold, Jerry! FF example was highly instructive.
I love my Euna. From this I know I will love the Oamp. Next, we wait for what 29 will create for the middle of the chain - the Mump?
😁
The FLWR
Half my pedalboard for fancy in & out buffers ? Nope... great demo yet.
sounds like an amp, but more! special little boxes, you're the best as always.
Thank you bud! Yes, these boxes really bring out the best in whatever gear you have! 👊
Your playing is so unique and great man. I’ve been a studio session man for years and I still I don’t know how you do the guitar pick thing with only your fingers.
Very Cool Andy!!!
Still don’t know the difference between both or why I would need one over the other?
Great review and playing as always! Very interested to know if I just use an EQ pedal (like GE-7) if I would be able to match the same with EUNA's sound
"Squishy and mushy and very gross"
Thanks Andy, very interesting. One question: Why not just put the EUNA immediately after the Fuzz Face rather than bypass it?
If you check out the video on 29 Pedals’ channel about the euna, he discusses this.
@@studieslessonstheoryetc141 Thanks! I will check it out. :-)
@@studieslessonstheoryetc141 I watched the video at 29 pedals and yes, he addresses that question exactly. I'm not sure I understand it all but it was well worth watching. Thanks again for taking the time to point me over there.
@@geoffedwards189 no worries!
Woah you need to show us your attic
Just a run of cables to the garage where the amp booth is 👍🏻
@@AndyDemos You're so fricking awesome man
The odd thing is, Andy, all your other videos sound great without these two pedals. Definitely do not sound like when you bypassed them in this video. Did you set your amps lower so they sound worse without them?
I always used some kind of buffer to handle the long cable run at my home studio. For most of 2020, I used the EUNA and now I use the OAMP! Before that it was a custom buffer that didn't really do it for me. Regarding the amps, I never play tricks like that, they are always loud around 4 on the volume, thanks!
yeah he did mention 'ive been using the EUNA' at the start...
🤦🏻♂️
Euna is great ... adds clarity. The OAMP, though, is super noisy. I must be doing something wrong.
What kind of noise? Ground hum, hiss, static? Does it do it with no other pedals connected? These are very low noise by design.
@@AndyDemos When I run it alone, it's pretty quiet with input Hi and output Lo. Otherwise I get a distractingly loud hiss--even when I adjust the levels on the pedal and the amp ... too much, and I lose dynamics. When I add the EUNA before it and switch it on, I get a crazy loud pop then hiss. If I then switch the EUNA on and off, the chain gets reasonably quiet again. I also added the FLWR in between (set 3, B, 0 for the best sound). Works great so long as I don't change any of the switches or knobs. All together, I do noticeably get more clarity and punch ... very nice. Oh, and running at 9 or 18 volt doesn't seem to make any difference.
@@paulvanheuklom6439 The OAMP is capable of a lot of clean boost, 29dB. So I'd start with everything at unity and see where the noise floor is. Unity gain on the OAMP is with In/Out both set LO and the Level knob around 2 O'clock. Give that a whirl and see if you still hear hiss. If you have an amp volume low and a super high clean boost, it will raise the noise of anything in your whole chain, so this is why I'd suggest starting at unity first to see if the pedals are behaving normal. Regarding the power, the Whatever input means no tone change will occur even from voltages from 7 to 35 either DC or AC! - that's the beauty of it. You can also contact Jesse at Believable Audio, super nice guy!
@@AndyDemos Not sure what I did other than fiddle around, but I found the magic. I would have thought it impossible to improve on the tone of an LsL Saticoy plugged straight into a Two Rock Studio Signature amp, but boy, oh boy, that last 5% makes a big difference--so much so that it's now hard to switch off the EUNA and OAMP without feeling I'm missing something. Thanks, Andy, for all your suggestions.
Beginner question: If that means that when you're using a fuzz, the EUNA is bypassed and it's like it's not even there, isn't that a drawback? You paid for it and it's not in use...
Usually vintage fuzzes don’t like a buffer before it (they get noisy and compressed). So, the loop option makes sense if you want to use the EUNA at the beginning of your pedalboard. You don’t have to route it this way, I use my EUNA at the end (nothing in the loop). This way you can get the benefit of a buffer at all times.
How do you like the budda amp?
Does this make the setup 58?
Is there any way someone could simply explain the main differences so I would know which one should I buy? I watched the video but i want to know what you guys think or if there is anyone who tries them? For now I think I’d get the oamp..
They are pretty much interchangeable but the OAMP has more boost on the input and output stages plus a bit more tone shaping. It all depends on your needs, I've used either as a buffer at the end of a pedalboard for a while now.
@@AndyDemos thank you very much! ✌🏽
I’ll go for the oamp 😬😌
Seems like they have a place with certain studio players , not for the everyday player. 500 bucks I can buy something "more funner" for me anyways.
I mean, I use my TU2 first in my chain and a DD3 at the end, which is totally the same thing.
Sure that’s the basic idea, buffer on each end. These go a little above and beyond the average Boss buffers in terms of headroom, noise level etc. Like all the gear that’s out there, you may or may not need these but it’s nice to know there are high end solutions coming out. Thanks!
I like how everyone that wants these two pedals but can’t afford them go FULL HATE on why they’re useless. transparent motives, not tones.
And for everyone else just tweak the EQ on your amp and or get a GE-7.
Bro you got a room for your amps? Cmon man. Next your going to start tucking in your pedals in bed and start sleeping in your ca- maybe that'll get my fuzz pedals to be more agreeable... you might be on to something, Andy
Haha! It’s the same little amp booth I had at PGS from day one. Really helpful to have that and be able to play at proper levels.
Talk about marketing hype--someone explain to me how the EUNA is going to "restore" my tone, when my tone hasn't lost anything, yet. Think about it: if the EUNA is the first thing you plug into...where, exactly, did you lose anything that the EUNA can restore??
The EUNA has, of course, been out for a long time, and it's great at what it does, but it's overpriced and gigantic, and the OAMP continues in the same vein. They both take up way too much pedalboard real estate. I can get a buffer and a booster for 1/5 the price and 1/10 the physical volume that sounds just as good as the EUNA and the OAMP. I don't need a complicated, expensive power supply that takes "whatever". Everything on my pedalboard runs at standard 9V DC.
These products are for blues lawyers who are never actually going to have 50-100 foot cable runs on stage, but have tons of money to spend on their hobby to impress themselves.
Well, you’re wrong - Play one first, ask questions after…if you still have them, which I doubt you will..
Wrong. Have you tried one? It’s pretty simple. Plug your guitar into your amp with a 4 inch patch cable. Then plug your guitar through a 10 ft cable into pedalboard (all bypassed) then another 10 ft cable into your amp. If it sounds the same, you’re either lying or you know magic. You do understand that one day YOU TOO will grow older, hopefully make more money and will be hated by those 20 years younger than you right? Also a pretty simple concept.
@@winstonsmith8236 Hey man, it's just a studio grade preamp. You seem to be overthinking this
Someone doesnt understand electronics or physics, and they also have trouble forming an intelligent argument... 😂
