Up for sale is a USED PREOWNED VINTAGE CLASSIC OLD SCHOOL ROCKFORD FOSGATE PUNCH BASS POWER OVAL AMPLIFIER KNOB. Knob has a top fin chip missing and is shown in pictures 5 and 7. This knob was mine and I used to use it in my RF Power amp. I removed knob a couple years ago and been stored for years. I had forgotten about it until I found it a couple days ago. Knob has only been used by me as I have been the only owner and I purchased amp new! Knob is ...used but still in great condition with signs of wear and use (SHOWN IN THE PICTURES). Knob you will receive is EXACLTY the one shown in the pictures (SO EVALUATE PICTURES CLOSELY AS THEY ARE ALSO PART OF THE ITEM DESCRIPTION). I believe the pictures speak for themselves. Any questions and feel free to ask. I answer any and all questions promptly and precisely. You may want to consider checking out my other cool stuff or items I have for sale. Thanks for looking and GOOD LUCK TO ALL!!!! I NEVER USE STOCK PHOTOS OF ITEMS AS I TAKE MY OWN PICTURES OF EXACT ITEMS BEING SOLD AT THE TIME!
