String change caused improper balance, how to adjust piezo pup?

[4-string]

I put a set of TI flats on my fretless Godin, and the E and A string are lower in volume than the D and G string. This thing has (what looks like) a fixed piezo bridge? Is there any way I can correct this myself?

I could always put the black nylons back on, they sounded OK, and were more even volume wise.

Thanks.

Couldn't resist....

It depends...how do you LOOK in black nylons?

Ba-da-BIM!

OK, I had it coming......

Needless to say, I am drop dead gorgeous, with our without black nylons.

For all you dirty minds here, I am talking about STRINGS.

hee hee, "nylons"!

loosen the strings and lift up the saddle to see if there's something in there that's shifted. the saddle needs to put equal pressure on the pickup underneath it to sound right, so partial shims and whatnot can mess up the string balance.

the saddle itself also needs to slide in easily enough to transmit the full string pressure to the pickup while not being so loose that it leans at an angle, and the bottom of that saddle needs to be absolutely perfectly flat.

yep…
this is all true…when you changed strings, did you happen to disturb anything on the bridge?

and when you're done, let me know how the sound of the flats compare to the nylons as I may be changing strings on the old Carvin AC40…

I thought the bridge was fixed, it doesn't seem to move at all, but I'll loosen the strings and have a closer look. The silk wrapping at the ball end of the TI's were just a tad short, so the strings were angled over the bridge just after the silk stops. Could that be what causes this, maybe?

Good thing I didn't throw away the black nylons.

Thanks.

We're talking the saddle, now,...not the wooden bridge, itsself...and you should be able to lift it right out of the slot if the strings are slack enough

The string should not be supported by the bridge saddle on silk...it doesn't matter how close the silk comes to the bridge, as long as the string isn't resting on the silk

DON'T throw away the black nylon strings...they last FOREVER! (almost )
