It has some resonant-ish colour in the (low) mids, but I guess it's due to the rubber holding sleeve. That sleeve has been recently changed by default design, allowing finally noiseless handling, when until a couple of years ago, it was a flimsy plasticky sleeve, which resonated on the highs, vibrated, had bad handling noises and looked quite fragile. This new version seems more reliable, but still don't expect super-high performances. Its preamp is still quite noisy, and the coloured output could not suit every task.
great for live use, specially for loud instruments.
