So, I have this minty Pinball refinery MET, documented 1st time owner - no errors including hammer mech works perfectly... Edit: For trade only. In terms of upgrades, they are here and the sheet below: Colordmd Pingraffix Creeping Death speaker panel Snake Red LED Eyes with fangs and tongue decal Matching Powdercoated coin door with chromed Pinbits dress slings/protectors in fluorescent Upgraded Laser Cut "Metallica" side rails and "M" hinges With orange inserts New (March 2021) orange perfect play orange rubber Upgraded hammer 3d snake mod Leg protectors Code & Music Update: Since Im getting a lot of questions on code/music, code is up-to-date 1.80 and using pinball browser a lot of music has been changed. Presently, on the machine is Metallica: Enter Sandman & Fuel. Then, Ive added Pearl Jam: Why Go, Dissident - Beatles U2: Helter Skelter - Led Zeppelin: Immigrant Song, R&R - Ozzy: Crazy Train - John Paul Jones: Goose - Genesis: The Knife - Deep Purple: Highway Star - Kiss: Psycho Circus, R&R All Nite - Stones: Sympathy for the Devil - Tool: Vicarious - Rush: YYZ, Limelight. All song volumes have been levelled and themed heavy thought out. For example, Sympathy for the Devil plays during Snake multiball. Since you have Metallica's original song lengths, most 6 - 8 minutes, I added song edits to the end of songs (that's why there are 2 songs) so they kinda act like Easter eggs as you only hear them during long ball times. All original songs can be easily put back on with a simple code update.
