detune a patch

Use Transpose stomp in first stomp. Take it down one notch.
You can either drop or raise tunings using this feature.
It's got a very slight latency but not noticeable in a live situation.

Doesn't the latency increase with every step up or down? The latency is a lot more noticeable if playing a clean sound.

Oooo that's a bit strange. Check to see if you have a direct level or mix parameter that needs adjusting somewhere. Check youv'e put the transpose first in your FX chain.

From the Deeper view manual....
Transpose
Think of this as a “digital capo” for your instrument. Simply set Transpose as desired to play in a different key. Set it to -1 or -2 for drop tunings. Transposing by -12 will turn your guitar into a bass.

No mention of hearing original signal.
Check you've not selected 'Parallel Path' in the 'Rig' menu. That might cause you to hear both tunings. Check this is not activated by pressing the Rig button and checking the options for parallel path are not selected.

I hope this helps.

I'm also getting the original signal along with the transposed signal. I ensured parallel path is off and tried a bunch of other settings in various menus with no luck turning of the original signal...any other tips out there to solve this?

Both...I was using an acoustic guitar...cranked the sound, still hear it, then used phones and turned them up and was able to isolate the transposed sound. Guessing it will not be ideal for a live setting when using the acoustic thru a small PA.

Strange, I've used transpose quite a few times and never had the unaffected signal come through..

If you record with this function you can hear the result. Only the detuned signal is on the record. The thing is, when you play a bedroom level you hear your guitar strings and the detuned signal. If you play very loud at rehearshal you only hear the detuned sound.
