Equipment Review: 29 Pedals / Credible EUNA and OAMP Audio


I didn’t want to believe the hype. Honestly, I thought I had a pretty good signal chain, paid close attention to the order of the signals, and had buffers in the right places. So do I need the 29-pedal EUNA and OAMP? Well it turns out I did.

The EUNA is a top level buffer / preamp / boost in your chain with an effects loop specially designed for those pesky pedals like vintage fuzz and wah, which are super responsive to buffers and indeed other pedals . Ideally, you want to go straight from your guitar to a buffer and then to the rest of your pedals. In a perfect world, you also end up with an output buffer to compensate for impedance imbalances and signal loss, but most of the time you have to put in a vintage fuzz or wah (or set to it) first. ‘before) then a tampon. Now it can work, and players have been doing it for ages, but it’s not optimal. Additionally, there are possible implications further down your signal chain. This is where EUNA comes in.

Connect your guitar first, then put those pesky and sensitive pedals in the loop and off you go. But wait, there is more! EUNA also offers “EQ options”. There’s a low switch to bring out the bass in your signal, an illuminated switch, and also a high switch to enhance presence and treble respectively. Improve is the key word here. They don’t hit you with those curves but rather lift them up and are very handy depending on the guitar, mics, or amp you’re using.

It is important to note that there is a noticeable boost in your signal with the EUNA and this is intentional as well as high quality buffering but nothing ridiculous. Maybe a few decibels. The result is definition and richness that you probably haven’t noticed before and it also contributes in a very positive way to the pedals you chase after in your chain. Plug your guitar into the input, the problematic pedals into the loop, and connect the output to the rest of your chain. The loop pedals are only active when you turn the pedal off and so the buffer is off the chain but the rest of your bottom of the line pedal is intact. When you are done with these pedals, simply re-engage the EUNA.

OAMP is similar in function with some minor changes. First and foremost, it’s an output amplifier capable of running signals for hundreds of feet without signal loss (and again, very high quality buffer). The OAMP has a small presence knob to add or subtract sparkle to your signal, a level knob to balance and compensate your signal level, and two switches for input and output calibration. The input switch allows high, low and bright signals while the output attenuates low, high or dark signals to make your signal less bright if desired. In general, I keep mine low input, high output, and a touch of presence and the level knob to taste. The OAMP also has an effects loop in case you want your modulation, delay or reverb in the loop or in case some of them are unpredictable and / or vintage effects.

The combination of these two pedals is downright striking and now I can’t imagine my pedalboard without them. Discover them HERE.
