Sound — 8
My signal runs from a BC Rich Bronze-Series Beast to the RC-20XL, then on to a Line 6 Flextone III Plus. There is no extra noise added by this pedal, but there is a loss of tone when connected after distortion. The instrument, microphone and auxiliary inputs all sound great. The built-in guide tones are pretty weak, but I use them as a tempo marker.
Overall Impression — 9
I play mostly metal and shred. This pedal works great because the instrument volume does not compete with the loop's volume. I have been playing for about 4 years, and I don't know why I hadn't gotten this pedal earlier. It is great for forming a one-man band experience as well as practicing your soloing and improvisation. If it was lost or stolen, I would definately buy it again, after beating the person that took it! I compared this with the DigiTech JamMan, and I found that both pedals sound exactly the same, but I chose the Boss RC-20XL because it was cheaper. It would be nice if it included a Boss FS-5U footswitch to cycle through the loops or play a phrase in reverse, but it's not a necessity. Do yourself a favor and check out this amazing pedal.
Reliability & Durability — 9
Like all Boss pedals, this thing is built like a tank. I would definately use this in a gig without a backup. It's also best to use this unit with a power supply, as it eats batteries like there's no tomorrow. I have dropped this pedal on the ground from about 6 inches (by accident! ) and there is absolutely no visible damage, and the unit still functions perfectly.
Ease of Use — 10
My RC-20XL was made in 2004, but is still in mint condition. The manual is very easy to read - it even has a Quick Start page, allowing you to get killer loops right out of the box! It's great to have one pedal for creating phrases, and another to stop and tap tempo. Definately a welcome addition to both a beginner and a virtuoso's pedalboard.
