Paraloop Single Parallel Loop Box with Mix Control

Nice addition to an effects loop. I use this in my Mesa Stiletto Ace fx loop with an SPX-90. Huge improvement in tone vs. using just the Yamaha unit in the loop. It's very versatile - it's at home on the pedalboard as well as in a rack. It uses either a battery or Boss 9VDC PSA power supply. There's also a bypass switch on the unit allowing you to take the effect out of the signal chain. This feature can also be accomplished using a remote footswitch when rack-mounted.I feel it's a little pricey considering it's basically a one channel mixer. However, the build quality and transparency are, bar none, top notch.
