Kevin,
Thank you for the thoughtful reply. I think you might have missed something here though. That circuit is not a bias vary trem. It for the Bandmaster with the signal vary tremolo. . As cool as those output stage bias vary trems sound I've experienced first hand why you discourage their use. It really tough on an amps....
I agree that this circuit does not have a wider range. The main advantage is the lack of ticking and noise issues compared to the Fender LDR ciruit. Also the footswitch is little more convenient since it does not require negative voltage from the bias supply. It is rather fast like the Fender circuit so I increased the value of the timing caps to slow it down.
You have an excellent point about the gain level of the stage I'd apply it too. That's definitely in need of consideration. The J-Fet solution really would be ideal....I'll try it out. Thanks!
Thanks!
