I have a Boss PM-5 which I have honestly never used. I bought it used and it has just sat. I also have a Boss DD-3 which I also bought used and hardly ever put in my effect loop. Both have been gigged and power on. Jack on the DD-3 can be noisy if it gets loose (just make sure it stays tight!) Not really a problem but I want to be upfront about the Pedals. I also have a Boss 9 volt adapter and daisy chain so you can power your pedal board. Any trade interest PM me!
