An input driver that replaces a conventional buffer, EUNA is built to protect and condition your instrument's signal to prepare it for whatever you want to do with it. Console grade build, three great sounding filters, and an alt-path insert loop for your classic fuzz and wah circuits that don't want to be buffered. Also features the 29 Pedals WHATEVER power supply, which accepts 7.5 to 35 volts of AC or DC in either polarity with no change in tone. EUNA is made by 29 Pedals in California.
Even a few true-bypass pedals and 20' of cable can hang out your guitar's output and make it feel mushy and dark. Buffers can help, but they are often very simple circuits that create sonic issues of their own.
EUNA is an Elite UNity Amplifier. It is designed to protect and condition your guitar’s signal. Use it in place of an input buffer. Plug directly in, first in the chain. You can safely remove all other buffers after it if you wish. We recommend an output driver at the end of your chain. You can use a conventional buffer, or try our output amplifier OAMP. Plug your guitar directly into EUNA with the shortest cable that is convenient.
EUNA features an effects loop that activates when EUNA is OFF. It was designed for use with vintage or vintage-style fuzz pedals. The interaction between your guitar and your fuzz is disturbed by any buffering, so EUNA’s effects loop allows you to switch between a buffered input and guitar-direct-to-fuzz. You can also use the loop to remove your tuner’s buffer from the signal chain. Let us know what other uses you find for the loop! If nothing is plugged in to the loop, the pedal is true-bypass when switched off.
EUNA features 29 Pedals’ WHATEVER power supply. The WHATEVER power supply accepts 7.5 to 35 volts of AC or DC (either polarity) with absolutely no change in tone. It’s true!!
EUNA has three sweetening circuits - Harmonics, Bright and Low. Low adds a little bit of low end. Not too much, just a little bit for some sweet oomf or to make up for low-end loss in your pedal chain. Bright adds some brightness, and Harmonics pushes the air band where guitar harmonics are. Harmonics adds sweet, tube-like chime to any rig.
EUNA preserves "touchyness" and "snap." There is also an increase in effective dynamic range of your signal, and in some cases coil noise is reduced! The custom-tailored load kicks the resonant peak of your pickups out typically about 5 or 10k compared to a load of a few true-bypass switches and reasonable cabling. The pickup’s top-end rolloff is smoother too. You'll feel more chime and less pinchy top-end.
EUNA will take over +18dB input with extremely low THD* - many other pedals fold about +10dB or less! The extra headroom on the front end means that EUNA will pass through your entire signal. That extra headroom means that fast transients won't ever run out of room - no relatively normal electric guitar could clip this, even for an instant. It's absolutely flat from 10Hz to 50kHz, but all the above features create a perceived tone "sweetness." EUNA can be modified to accept up to +22dB!
Connect power to the WHATEVER power input with a standard DC plug. You can use AC or DC, either polarity, 7.5 to 35 volts. EUNA consumes about 100 mA."
