[quote="evilgus":3b5j8b9s]A friend of mine is selling an OBP-3 with complete circuit pretty cheap, so I'm seriously considering the upgrade. Aside from an extra hole for the mid pot and replacing the Blue EQube with mid-freq switch, is there anything major to consider? I guess I'd lose the 4-way selector to a pickup pan, so won't have series/parallel options anymore. I tend to only use bridge pickup and both pickups in series (is that loudest?), so probably won't miss it.
Cheers,

I am glad I kept the 4 way switch. With it now being active, The series/parallel gives you a different gain and tone response to play with. Especially with tube amps. When mine was passive, I only used it on the louder setting.
The pan idea sounds good too! Maybe you can do that with the volume knob hole and lose the master volume.
