A high-quality buffer equipped with three types of EQ filters and an FX loop. A groundbreaking buffer + sound filter for complete treatment of your instrument signal. EUNA (Elite UNity Amplifier) is a buffer pedal designed to reinforce signals and enhance the original sound of instruments. Used as an input driver in place of a traditional puffer pedal, it improves signal resolution and prepares the basic clean sound. In addition to the highest quality buffer, it also features three special sound filters. The three switches - Harmonics, Bright, and Low - push specific frequency bands carefully selected with exceptional taste, further enhancing their presence in the ensemble. In addition, by using the effects loop, you can also use fuzz pedals or wahs where you want to avoid the effects of the buffer. This is the perfect buffer pedal, created with the unique perspective of 29 Pedals, who are also involved in the design of professional audio equipment. EUNA is committed to providing the highest quality instrument signal on any pedalboard. ■Product Overview Degradation of sound quality caused by the large number of shielded and patch cables connected is a perpetual challenge for guitarists and bassists seeking high-end sound. The sound is somehow cloudy, hazy, and muffled. But if you don't want to remove anything from your pedalboard, the EUNA is the perfect solution. The EUNA acts as a buffer/input driver, boosting the signal to a vibrant, lush sound. It completely eliminates the tone impurities that come with cables, reproducing a pure, bright, and beautiful full-size sound. It dramatically improves the resolution of clean signals without significantly altering the existing sound. There are many benefits to using EUNA, but one of its biggest features is that it gives the sound a sense of "breath" and "three-dimensionality." It also expands the signal dynamic range and reduces coil noise. By adjusting the clean sound, the effects in the subsequent stages become more pronounced, further enhancing the overall presence of the sound. It significantly improves the sound while retaining the original character, so once you turn it on you'll never want to put it down. ■Three sound filters First, when you turn on EUNA, the sound becomes sharper and you will feel that it has more presence in the ensemble. Additionally, EUNA features three sound filters, allowing you to fine-tune the sound texture to your liking. Low pushes the low end, Bright pushes the high frequencies for clarity, and Harmonics pushes the air band to emphasize the guitar's harmonics. The filter is tuned with exquisite precision, with the unique flair of 29 Pedals, to reliably enhance the tone without significantly altering the original sound of the instrument. ■Effect Loop The effects loop on the EUNA is active when the EUNA is turned off. Vintage-style fuzz and wah effects that are sensitive to buffers can be placed within the loop to eliminate any sound-changing elements. It's also useful if you want to remove the buffer from the tuner. When there are no connections in the loop, the EUNA is true bypass and off. ■WHATEVER Power Supply The WHATEVER power supply supports all power types, from 7.5 to 35V, AC or DC, center negative or positive. By creating a perfectly managed power supply using a step-up switching regulator circuit and a linear regulator and supplying it to the circuit, it is possible to extract 100% audio performance without changing the sound, regardless of the type of power supply you have. ■DIY friendly EUNA is designed to be DIY friendly. The op-amp is socketed, allowing you to quickly try out various parts. The PCB also includes a DIY guide that allows you to make various modifications. By simply unscrewing the main body, you can quickly access the entire audio circuitry without removing the board, while avoiding interference with the power supply. The EUNA is designed to give 29 Pedals the best sound possible, but it also allows users to customize it to their liking. (If you modify the product yourself, the domestic warranty will be void.
