I received this pedal the day before a 2 show weekend. I had not had a chance to use it before the 1st Show. Selecting Sweetened Guitar preset. I could not believe how In tune my guitar was! I had a Poly but it never got as precise as The Peterson StroboStomp. The Buffer is just as impressive. Running 40' of Solderless cable and some pedals in between, it sounded like I was plugged directly into the amp! The following day was an outdoor gig and was very pleased that I could see the display in direct sunlight! It's well worth it if you're a working Musician. My whole band is now tuning from my new Peterson! I'll not settle for anything else!
