Gibson Falcon

[Pablomago]

I just got a '63 Gibson Falcon (GA-19RVT) that I'm loving except for one thing. It sounds like there's a hard wired bright switch in the "ON" position. I was told that there is a cap that can be replaced or removed to cure this. Does anyone know which one? This is the version with the 6C4 tube in the reverb circuit.
Thanks!

In my ignorant opinion, 500pF (0.0005uF) for C22 (between the plate of V2 and the grid of V4) is on the small side. If you can find a good* place to mount a switch, tack a cap of about 1500pF (0.0015uF),in series with a switch, in parallel with that cap.

This lets you A/B the two values of 500pF (normal) and 2000pF (500pF in parallel with 1500pF) to get a feel for what you need to do.

A rotary switch to let you try a bunch of different values at one whack is a good thought, but harder to get, harder to mount solidly, and harder to add safely.

*good place - mounted to something solid and taped up so there's NO way you can touch any leads when you change the switch. It WILL pop when you change it.

Hope this helps!

And also looks like theres bright caps all over that amp as well as those Don mentioned. I have one in my shop and we'll see what it does so give me a few days but I did a Discovery not to long ago and it was bright also but man it was awesomely bright,warm and had all original NOS tubes and wasn't very loud but had amazing tone.

I must have a dog......no real highs at all, not much power....maybe the crappy old Jensen C12R?

I pretty much always hate the sound of old Gibson amps.

You know I didn't like the clean that much but then again I'm a distortion player and at 10 it rocked so that's where I played it but the tubes I'm sure had a great deal to do with it.
