BENAVENTE GUITARS 3 BAND EQ ONBOARD BASS PREAMP. Auction is for one pre-wired 3 band preamp wired: treble and mids are boost/cut and bass is boost only on push/pull pot for active/passive switching. Volume and blend pots included for an additional $25.00. Free shipping Continental US only. International pays actual shipping. I cannot believe I need to state the following but here ya go: Read the description to understand what you're bidding on in this auction. The picture is just a picture of a Benavente preamp ready for shipping. The picture is showing a preamp with the vol and blend pot upgrade and just because you cannot see the battery clips on the back side, trust me, they are there. A jack also comes with the vol/blend upgrade upon request. I hope this helps clarify what shouldn't be confusing if you read the description in the first place. Thank you...
