I purchased this used about two weeks ago, but it doesn't have the sound I'm looking for, so I'm putting it up for sale. I've lowered the price to its limit at this point, so I'm not considering any further discounts. Functionality confirmed. Instant purchase OK. - Brand: E.W.S. - Model Name: Tri-logic Bass Preamp II - Function: Preamp - Controls: Tone, Gain, Volume - Connection Terminals: Input, Output - Included Accessories: Original box Thank you for looking.
