Just posted a long, detailed account but got logged out in the process and lost it all! ARGH! It this now the default for the forum? Anyways, loaded up the new Scumback M75-PVCs in my Germino 4x12 last night and have logged about 2 hours on them now, comparing them to everything I own and in many different amp/cab/speaker combinations, for reference. These replaced a quad of Weber-built M75s, which I absolutely loved, BTW. However, these new Seavall-built M75-PVCs take the whole game to a new level, as did the Seavall-rebuilt M75-LHDC did when I first heard that and compared it to the old stuff. In addition to the added reedy, woody, vintage mid 60s Greenback vibe, I noticed increased clarity, air and sustain in the M75-PVCs compared to the old M75s which I still have loaded in a Germino 2x12. They have so much going on, it’s really hard to put it in words. You gotta’ hear it to believe it. Just killer. The Thorn video on the Scumback website is an incredibly accurate comparison of these different speaker types but, IMO, the M75-PVCs (and the Seavall-rebuilt M75-LHDC) shine even more when you dial in the amp to match each speaker. Not sure if it’s the PVC or the new manufacturing process or both, but these new M75-PVCs sound better with my other non-Marshall style amps than do the old M75s. This quad in the 4x12 just seems to sound amazing with every amp I throw at it, even the D-styles! The Maz 18 and Glaswerks were kinda’ muddy with the old M75s, no matter how I dialed the amps, but just come alive with the M75-PVCs. Glad I took the chance on these! I now feel like my Germino 4x12 rig is complete. Now, I'm gotta' get two more for my Germino 2x12! HIGHLY RECOMMENDED! Edit: Added some pics. Sorry I didn't take any of the front of the speakers. To dispell any rumors that wood screws are used to mount the Germino handles.
