Hello All, SOLD
I have a John East preamp for the Marcus Miller bass. Super easy install (no soldering required) and sounds absolutely KILLER. This is the version that comes already pre-mounted, so its drop in and play. You know how your Marcus sounds "OK" but doesn't really have enough "oomph"? This solves that issue, while giving you that fantastic sound. More on that here.

The pre is only 2 months old and was barely used. I still have the box it came in! Only selling cause I just sold my Marcus and the buyer elected to have the original pre put back in.
300 bucks shipped...they go for 350.00 before shipping, so your saving 50 bucks, plus shipping fees on what is, essentially, a new item.
I accept Paypal...I can ship outside the USA but it will be a little more. PM me with any questions.
