I have a discontinued Digitech BR300 effects pedal that I use. I would look for a newer version with better effects and samples.Ok, I had been using a Joyo headphone practice amp. This is the second one I bought that has now crapped the bed! Any suggestions on a replacement? It needs to have an aux in so I can connect my mp3 player. Something reliable. I miss my old Pocket Rock-It. That thing lasted for many years.
