my dad's got an old 60's coronado II that hasn't seen the light of day in a few years. having grown up around that guitar, and as a kid thinking my dad was a rockstar because of it, i'd like to get it back in playing shape. i did the setup on it a while ago, and discovered some problems, mostly having to do with the electronics and the bridge.

the pickups seem very uneven in their response, mostly at the bridge. some strings can barely be heard. any thoughts?

some of the little "T" shaped things in the saddles(pardon my lack of vocabulary) are missing their all thread adjustment screws. does anyone know where i can find replacements? should i just by a whole new bridge?

also, any advice on doing the general setup would be helpful. i'd like to put 11's on it, to get more tone, and i don't know exactly what gauge are on it now, but they're pretty light.

thanks!

The bridge pickup will sound audibly weaker than it's neck counterpart normally. As to some strings being barely heard, dead strings, improper metal alloy strings, improperly adjusted polepieces or simply a maladjusted pickup can cause this. In extreme cases, if the electronics are in really nasty shape, you'll get intermittent response from the pickups as well. FWIW, you have DeArmond pickups OEM in that guitar and they are weak to begin with. Good, but weak.

Keep in mind that when it comes to a vintage piece such as your's, value wise, the less components you replace, the better. So, you do not want to replace the entire bridge. Rather, only what is absolutely necessary.

The individual bridge saddle adjusting allen screws (I presume these are what you are referring to) are readily available. As a matter of fact, any established guitar tech probably has a drawer full of them. Unfortunately, I forgot the exact size. If memory serves me correctly, they are #4-40 x 3/8 but I can't swear to it. Your best bet is to bring one of your's to a better guitar shop as a sample.

If you're intending to go from light to heavy strings, I'd do an approximate truss rod tightening with the strings off first as the neck is probably bow warped to begin with and the less pressure the neck is under in order for you to move the rod, the better.

I'd echo Martian's responses... in summary: renovate, don't replace! Try googling "luthier supplies" and you should find any small parts, saddles, screws etc readily available.

Problems with electronics should be easy to fix, as there's very little components involved! Most problems will be down to poor connections or worn 'pots' (the bit behind your tone & volume controls).

Do you really need 11 gauge strings? I'd restring with 10's first and try again (especially if you don't know what gauge is currently fitted).

If you have dead spots when you play, consider getting the frets dressed by a Pro - it shouldn't cost a fortune and can make a big difference.
