I should add that prior to the Ditto, I bought the X4 Delay/Looper back in October, and have - to date - experienced no issues whatsoever. I don't know if they use the same switches on all their products - anecdotal evidence from Loopers' Delight and similar forums suggests that other companies including Line6 use them, too, and that the failure rate is appreciable. I belive there's at least one place specialising in replacement with more robust switches. However, as I'm in the UK, the postage costs outweigh the benefits. I do hope TC isn't expanding beyond it's ability to maintain quality control...
