I suspect one with that kind of fitting is more likely to come from shops for, erm, "specialist" interests. The kind with blacked-out windows and signs saying "over 18 only". ;-)

Ironically Tim I just got one of the older Behringer feedback killers for a bit less than you outbid me for. So all's well that ends well. Although I'm a bit less sure about feedback-killing since I couldn't get my existing box to kick in at our band practise last weekend. (Memo to self - bring the sodding manual next time.)
