David Drake:
Well, I finely stumbled over an ADA TFX4 with controller, and I believe is an older unit (Grayfaced. Man, I really wanted a blacked faced one to match the studio Rack) but it has some issues, i.e., Big delay when changing effects, noise on the Chorus at a certain sweep of its cycle and the flanger is much louder than the other effects. Is this something that can be addressed or not. I just want it top notch as it is going to my personal ADA museum.

rnolan:
Wow, not that many of them around, I've never seen one.  I've attached the manual.  Hopefully someone can help with your issues.

rnolan:
Also attached the schematics, hope that helps  :wave:

MarshallJMP:
What do you mean by "big delay"? Do you hear a clock noise? Strange about the flanger since it shares the same circuit as the chorus. Are you using a lot of feedback on the flanger? Is it better if you turn the FB down ?

I have had two of these and still have one that gets regular use. The volumes should be even across each effect, so chances are that yours needs a bit of a once-over. I have used a very experienced tech in my area to fix mine and he had it running as it should.

Also, if you didn’t know already, MarshallJMP will get you in the right direction.

Oh, and rnolan, if you see one of these for sale by all means get one.
