I, too, got a OLP MM2 on E-Bay for $230. It is the Natural/Maple with Tort PG.
Only 2 days in, the clover key pulled off the tuner worm. 2 days! So, I ordered some Hipshots, the MM specific tuning machines, and they didn't fit the hole pattern. The 2 smaller mounting holes lined-up, but the larger set didn't. I contacted Hipshot, who werer very cool and helpful on the phone, and they offered to take them back and gave me a Return Authorization and everything, but I decided to mount them anyway. I filled the old holes with toothpicks and re-drilled for the new tuners. It was kind of a cool "luthier" project and it came out well.
So, I have nice, upgraded tuners.
Next, I pulled the cord out of it, and it had the input jack washer and nut attached. The jack fell into the cavity, and I had to take the control plate off and re-install the jack tightly. Another "luthier" project.
Well, after I did that, the treble pot wasn't working. I pulled the plate back off, and if you jiggled the pot it would work, but it needs to be resoldered or something. I won't be the "luthier" on that one. I plugged it in to play it the other day, and it's working, although I wouldn't trust it in a jam.
Sorry for the long story, but those are examples of the quality issues.
Now, for the good points. The finish is awesome with a flamed maple that doesn't look like film. The Humbucker rocks! Awesome sound. The neck and fret are nice and it plays well.
Bottom line is, if you upgrade some of the hardware, like cheap tuners, and maybe the electronics, it's a great bass. I do like it and would recommend getting one. They are discontinued and available randomly through E-Bay, etc. I did contact the seller about the tuners, and they replied and wanted pics, which I sent, and haven't ever heard back. Whatever with them, I like the Hipshots, anyway.
