Ok it's just a Pocket POD but here is my issue. If you say the word Tack like I do (Southerner with just a touch of Northerner), it's two syllables "Tah-acK" with a hard T and a hard K. Very often when I hit a note on the guitar (send a signal to the Pocket POD), it produces this metronome-with-echo-like tack sound which constantly repeats. At that point I usually turn off the unit. Sometimes when I turn it back on the tack sound is gone, but then it usually comes back after a while. I bought the unit new - through Sweetwater; it's definitely out of warranty...so in your opinion is it just a failed electric part, SRAM, diode, resistor...and I should just toss the thing and look for a better product?? Thanks for reading…and considering the problem!
