Tone Generation for debug/building
Looking for some ideas since strumming a guitar while testing can be such a hassle.
hooking up an ipod that loops a recorded guitar signal?
This seems like it might work, but is the signal even ac? Is there a way to make this work so that the output of the effect being tested gives similar results like a true guitar signal?
what other methods can be used?

Other thing you can do is, if you have a delay capable of repeating a loop (DD-3 (hold), for example), that's your guitar signal generator.

The Freestompboxes Forum search function is soo great, use the search function..., the S E A R C H function.
looks neat, of course I messed it up...
On the RG keen Twin Tee iscillator
1.) does this require 2 seperate 9v sources or can I just jumper the 9v+ hookups together?
2.) Is that a connection where the lines cross under the 4.7k?
3.) how do you hook this up?
Let's say I have an input and output wire from an effect I would like to run this signal through. Do I just take the 100mv lead and attach it to the input wire for the effect I wanna test out?

1) No, that's the same voltage node, you only need one battery.
2)Yes, it is a connection.
3) Yes, that's it, the output goes to the amp; or you start testing with the audio probe connected to the amp if that's the case.

If you have a scope, a couple things might prove useful:
A triangle wave will more clearly show distortion/asymmetry rather than a sine (which is already rounded at the top).
The option for symmetric/asymmetric waveform can prove useful when sorting out phase inversion.

If you wanted to change the frequency of the RG Keen signal generator what parts would you change? like say if I wanted to had a couple switches so I could choose between three different tones.
thanks
