Ok, the short answer: They kill them. But many like the way the TB+ sound, but they do not sound like a vintage Thunderbird. The Epi ProBuckers do sound really close to the originals. I have had a '64 for decades and now have two VPs that sound fantastic, not even considering they are way less than a Gibson. I also have an'06 Gibson and it sounds least like a traditional Thunderbird of 5 I have. I'm not saying they sound bad, as that all depends on what you are shooting for, they just don't sound like the orginals. My '76 with sidewinders is much closer to the 60s version than the modern TB+. So it depends on what sound you want. Vintage? No question, ProBuckers. A modern take on a Thunderbid sound? TB+.
