This unit is barely 3 months old and spent its time with me in an MIJ Fender Jazz fretless. It is thus in virtually new condition. It is for sale as ACG are building a bass for me incorporating a more extensive pre amp (on the AC Guitars website under the Gallery section - look for J Type Custom 4 for Alan) and the Jazz + ACG EQ02 were acquired to keep my eye in and to learn about the ACG filter based EQ system so to speak. The bass has gone to a gentleman who prefer passive Jazz basses so the EQ02 remains available. For those unfamiliar with the ACG EQ system some more details are included later in the post. The unit is in the UK but I am happy to post to the mainland USA carefully packed and insured in transit. I am looking for USD $250 including posting and packaging plus transit insurance. If you are outside the mainland USA please let me know and I'll check that the P&P is not vastly different. Reasonable offers will be carefully considered too Although I'm new on Talkbass I have been a member of Basschat (the UK equivalent forum) for some years and have excellent feed back there under the same user name. Please find me on ebay.co.uk as alaind5750 too. These are exceptional on-board pre amps with a huge range of tones available. It is a straight swap into a Jazz bass and should fit most cavities. Please note a 9v battery is also required which sits underneath the pre amp in a space that has been left to accommodate it.
