I have one of those cheap ultrapatch pro's. I use it to be able to plug my guitar or bass into two or more sources. For example when I record bass, I like to capture a good bass cabinet sound but as well I want to go DI as well Just in case. So I plug bass into front hole. Run two cables out.
Here's my delema though. This thing is 1/4 inch but not tip ring send. So I only ever use it to be able to play guitar and bass into two amps and stuff. I mistakenly thought it was tip ring send. And was going to do the same thing with a multiple headphone send. But I cant because its mono. If it was mono for the first 12 bays and stereo for the other 12 it would have heaps more plugged into it. And be 10 times more usefull.
If I want to connect my pre's and other rack gear to it it wouldn't be ballanced cause its mono. So I dont. So your all thinking why doesn't this guy just buy a stereo 1/4 inch patchbay. Well they all seem to be mono. So I end up using those dicky one to two adapter things for this task.
