29 Pedals EUNA Elite Unity Amplifier Input Driver *Free Shipping in the US*

In the words of 29 Pedals:

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.
