I bought one of the original Strobo Stomp tuners when they first came out, around 2001. It has been used daily ever since. It has been repaired twice at the Peterson factory, once at no cost to me even though it was years past the warranty, and the second time for a very reasonable charge. The service was absolutely first class, and amazingly fast. Recently I bought the newest design for my grand daughter, who has been playing bass now for three years. Although my faithful old blue Strobostomp still works perfectly, the latest one has several very good features that convinced me it was time to upgrade. The first improvement is size, it is now smaller in every dimension, with I really appreciate. Despite the case being smaller, the display is significantly bigger, and easier to see at a glance. The color of the display can now be changed, which will be handy in situations where stage lights or bright sun sometimes make the blue and grey graphics hard to see. The biggest improvement to my mind is the ability to name notes as flats rather than sharps when appropriate. Calling B flat A sharp never seemed right.
