    ok...OPINION TIME - without checking these on a meter...which of the following would you prefer for a neck and bridge cap:

    .01 10% 400 VDC
    .01 20% 400 VDC
    .012 10% 200 VDC
    .022 10% 400 VDC

    The .033 I have now is hanging off a single coil pup, I think it sounds great. I have a feeling finding a .033 bee will be a long shot tho, tho the first chance I get I'm gonna have to head over to the grandparents and make a raid of my pops collection of old broken radios and other bits of old electronics.. maybe I'll get lucky.

    Yeah .033's are nice for single coils, I had one in my Tele. Look for an Orange, Orange, Orange striped Bee and that would be a .033 but you probably already knew that ;)

    On Doctor Vintage's website it shows the caps used in Gibson's in the 50's and it showed bees that were paper in oil and then some mylar. I know the black beautys with just the numbers and letters with the black casing can be either but didn't know that the bees could be, is this right? I thought that the bees were actually pio even if you couldn't see the oil spout or solder drop on the outside because they are sometimes on the inside of the casing. After looking at that website I am a little confused and just wanting to figure out what is right. Thanks

    I think Mylar came out around 1945, if a Bee does not have the filler tube or solder blob there is a chance that it might be Mylar or it could be PIO. Hard to tell sometimes.

    you know, what i dont get is why 50 years of knowledge and we cant seem to improve on capacitors, in fact it seems weve gone backwards.Why is this? I know old tubes were put through more vigerous testing in the good old days, especially those used by the military, they were tougher and well put together compared to todays tubes. Possibly the same theory with caps.

    I think they have improved capacitors over the years. Thing is, for guitar tone circuits, we don't want the improvements, we want the grit, the junk that comes from the old ones.
    For other applications, they throw old Bees in the bin.

    How about an orange drop question. I just found about 100 or so orange drops today and was just wondering what the letters meant on it. These are the first orange drops I have gotten to try. The letters are NPC - EL. I can't seem to find what these mean and it states the value, tolerance and voltage plain as day on the cap. I will try and post a picture soon but I can't get it clear enough to read the letters. Thanks

    I recently bought a vitamin Q for my strat and was kinda blasted for spending the extra money on a telecaster board! But the difference was quite noticable. Can't wait to do my LP.

    Ive been thinking about doing a 'dual tone' idea to my dot studio. Something like having a SPDT on-on to select between 2 different caps, RS .022 and an Orange Drop .047. Does anyone know what would happen if I use an on-on-on switch with a .015 and .047 will the current run through them both and act as a midway value or will it do something undesirable? I plan to be using a SD PRails quite alot so I thought a second value to choose from would be a cool idea for the single coil operation.
