The piano keyboard is one-dimensional; all the notes are laid out in a single direct line. When you get to the end of the keyboard you could certainly “wrap around” to the other end, and in that way you’re kind of turning the line into a loop. When comparing the guitar fretboard to a piano keyboard, people sometimes note that instead of one dimension, it’s two dimensions: follow along a string in one dimension; go across the strings at the same fret for the other dimension. Adding the “wrap” to the 2-dimensional plane turns it into the surface of a cylinder. (And now I’m sounding like the math geek that I am!)

@@KevinIlsen Thank you for the great response! Yeah, it does seem that a one-dimensional instrument such as the piano keyboard is not suddenly capable of becoming three dimensional. The "cylinder approach" to the guitar fretboard appears to have merit, though.

No reason why not as far as I can tell

Thanks

Go into the app on your smartphone and make sure the guitar output is all the way down to 0. It’s not sufficient to do it with the physical knob; you need to do it in the app.

​@@KevinIlsenthat worked!

Yes the amp does a nice job with acoustic guitar pickups.

Wish I could take the credit for the idea. I saw it mentioned on a couple of forums, and figured it would be helpful to show it in a video.

The Aux jack on the THR30ii would need a stereo plug. So if there are separate L and R outputs from your looper pedal, each of them would be mono, so you'd need a Y adapter to join them together.

I didn’t figure this out; I read about it in a forum. I just figured a video would be helpful.

Which one?

​@@KevinIlsenMax Gail, but you are too young

@@jackblack2321 Wojo? Never heard that. Most think Doc Brown.

In the video, I used a TS (mono) 1/4” cable from one output channel of the THR into one input of the RC3, and then a TRS (stereo) 1/4” cable from one RC3 output, into a mini TRS (stereo) cable that I plugged into the aux input jack of the THR. So, yes and no. But this didn’t give me true stereo. To do that you’d need two individual mono 1/4” cables going from the L and R line outputs of the THR into the L and R inputs of the RC3, then a 1/4” “Y” cable with two TS (mono) plugs on one end and a single TRS (stereo) connector on the other, to join the L and R outputs of the RC3 into a single TRS (stereo) connector, followed by a 1/4” TRS to 1/8”TRS adapter to connect to the aux input of the THR.

@@KevinIlsen Hi Kevin. Many thanks. Do you think either of the ways you discuss are better than the other?

@@thecaninebehaviourist really depends on how valuable you find the stereo effect in the THR. In my opinion, it's not worth the extra effort of hooking up the stereo cables. But you might feel otherwise.

@@KevinIlsen Thanks Kevin. I will bow to your, vastly superior skills and knowledge (I'm just an ageing noodler). Just about to upgrade my THR10C to the THR30ll. Invaluable video and advice! Cheers :)

@@KevinIlsen Hi Kevin. Last question. I've now got my new THR30ii - I've connected it to a Boss 500 as you described. When I run the volume up on the THR I get horrendous feedback. Am I missing something obvious? Many thanks.

Yeah; it bothered me at first but the comments that do thank me make up for it. I certainly won’t make this mistake again; I was rushing and didn’t bother to tune.

yes, plug cable form guitar to amp

Maybe the update reset the volume settings. Go into the app and make sure the guitar output is at 0. Not enough to do it via the physical knob, you need to do it in the app.

@@KevinIlsen yes you’re right. The update via my Mac was a touch and go affair. Very flakey and at first I was worried it’d bricked the amp. When it came back to life I restored from back up but it didn’t restore the amp settings. Now I can’t remember how the speaker tuning and audio streaming eq were set.

Make sure to go into the THR app and set the guitar output volume to 0. If you don't do this you'll get a lot of noise. It's not enough to adjust the physical knobs on the THR; you need to do it in the app.
