I'm wondering if anyone has modded one of the Ampeg B-15 NF preamps so they also have the '64 B-15 NC preamp (volume control post tone controls). The stock B-15 NF has the volume control pre-tone controls. This mod (so you'd have one of each model's preamps) is seen in the B-15 heritage reissue amp. The B-15 I have here has a printed circuit board so I'd have to cut traces in order to do this mod, which I'm not so sure I want to do. If you've done this and have a layout drawing, I'd love to see it. There are also a few other changed parts to realize this mod. Apparently, the two preamps sound different but I'm wondering if it's all worthwhile sound-wise for all the manipulation you'd have to do. Curious (as usual).
Thanks,
