Dedicated tuner out

[Colossal]

I would like to build a little input box to provide a mute switch with a direct signal pass-through but more importantly, a dedicated, no-loss/load tuner out for an always-on tuner. How best to handle that? Use a high impedance transformer to passively split the signal for the TUNER OUT? Looking at the Jensen JP-11P-1HPC 10k:10k.

Tuners usually have a high input impedance. That means you can can connect them in parallel without loading the signal. Simplest case, just use a Y cable, but that won't give you mute capabilities. To include a mute switch you can use a stomp box enclosure with a switch and three jacks:

1. Input
2. Tuner - connected directly to input
3. Output - connected to input through switch

Use an on-on switch to control the output. Connect the output tip to the center terminal of the switch. Connect one outer terminal to input tip and the other outer terminal to ground. This will ground the output in the mute position but will never ground the input or tuner.

Thanks a lot Tony! Good to know about the input impedance for tuners; I wasn't sure about that. I was trying to find something about mine (Sonic Research) but have not been able to verify. I will house this in a 1590B. I usually play with a very simple, direct setup and am leery about anything that soaks highs.

For anyone interested, the Sonic Research ST-200 has an input impedance of 1M.

yes, this works well. Alternatively, you can use a peterson or TC tuner with a buffer so that the tuner is on all the time and the switch mutes the signal to the amp.
