O.k., I have an iPhone with about 20 apps that require an iRig. However, Im DIYer with everything. On that note, trial and error is exhausting. My thoughts on this are that if I used an old tuner with an in and output with this setup it will work. Im unsure about the imp., and if the ios mic in cant be in parallel circuit. Would this be ok? Also I want it to be able with inputs from iphone/amp 1/8, 1/4 both mono and stereo. I know the IOS is unable to use parallel circuit...so if it was setup like the following pics, would it work and be safe for all componets
