如果是嗚~~~像mic的 feedback那樣, 通常是 Pickup本身的microphonic效應來的,
除非換好一點的pickup, 不然就要破音開小一點或離amp遠一點迴避feedback

很會feed 大部份是吉他的pickup 問題吧
我的吉他會feed，只有木吉他和大空心爵士琴
你不會是拿這種琴在開大破音吧
這樣不feed都很難
其他的琴倒是很少有feedback的情形

或者是你練習的時侯，琴不要面對音箱，也會好一些
真接面對音箱，feedback也會嚴重一些

I am using 15ft long cable and I tried to walk away from the amp.
My third string sounds buckle when I use my finger to pick it sometimes, but it sounds fine playing with pick but feedback is strong.

單一組器材通常很難去判斷問題, 器材還有配合問題, 所以要用不同器材實驗最好判斷, 例如你吉他接到另一台Amp, 如果還是一樣, 那就是可能是琴的問題, 或換一調不同導線Shielding較好的, 搞不好就發現正好是導線問題, 或正好一套雖然都不怎樣的東西, 但正好就配合
