For Sale FDeck HPF-Pre 3 in good condition with some light scratches and signs of use. Asking $80 shipped via USPS Priority in the Con US only. Paypal only, please. Sorry, no trades. I had originally flipped this over and used velcro to make the I/O work better on my board. Unfortunately, when I tried to remove the velcro it took part of the label with it. Otherwise in great shape and perfect operating order. It has been extremely useful on boomy stages and bad rooms but I am using a Tech 21 Q/Strip now that has a built-in hpf.
