Electro Harmonix 1440 Stereo Looper - Distortion for Guitars

On paper this is a great pedal, with lots of features compared to most at this price. However my unit didn't work for me as recording with any pedals in front of the looper resulted in a high pitched noise from the looper, recorded onto the loop. I tried various PSUs and leads and removing pedals one at a time, running only one pedal in front etc. With no pedals it was silent but with anything in front the noise came back. The noise wasn't evident during normal play but as soon as you recorded a loop it appeared on playback. It's a shame as otherwise it's a nice and easy to use looper.

Do not buy if your going to be using midi as a clock source.Very bad sound corruption and pitch changes using midi from any source(tried 6 alternative sources).Works ok without Midi.

Bought from a local supplier. Good sound quality considering the price, looping works well without using an external clock.It's unique selling point is, however, the midi syncing. It is very poor compared to even some cheaper pedals. I can't recommend this if you're going to use this in a midi setup because the midi just doesn't sync correctly. It seems to time stretch your signal EVER so slightly so after 4 or 5 repetitions you'll notice your loop is 1/32nd note out of time and it gets progressively worse as the loop repeats. It makes the pedal a £200 paperweight for me I'm afraid. I'll wait to see if they patch it in a firmware update but it's been out a month so far and no luck yet.I'll change my review if it's patched, of course, but out of the box it's basically useless.
