Our 2 dogs, a Lab and a Border Collie, love to lie and listen to me play. Nowadays I just play quietly thru a Roland JC22 here on the sofa and it's become part of our pack routine. At 9pm every night in particular they'll remind me if I've forgotten because that's when we play 'doggie in the window' where they get up with me for a cuddle and I'll play that song. I have to be careful they don't scratch my guitar as they get excited. Sleepwalk with the melody 'howled' sends them into fits...we have a number of simple songs they know and enjoy. 'I'll get a different guitar' is also understood and they'll wait until I return with another one (I've about a dozen) and 'greet' the guitar. Anyway...yesterday I was sitting here working out some Bach and they were lying on the floor when, to rest my head a little, I decided to turn the JC22 chorus depth and speed controls up full, just out of curiosity. Then I tried 'Jesu, Joy Of Man's Desiring'....which sounded very seasick. The dogs, who had seemed to be sleeping, got upset. They looked at me....looked at the amplifier...looked at me again...then looked at my guitar with that worried look dogs do. Then Mimì came over and sniffed and licked the guitar. I could nearly hear her thinking....'guitar sick?....what wrong with guitar?...' Apparently, they are plug-in-and-play dogs who prefer minimal effects.
