I have a dilemma. I would like to add another pedal or two to my board. But my PT-2 is fully populated. I need more space. Do I jump up to the Pedal train Pro? I keep putting it off because with all its convenience, it starts getting really big, heavier and $$$. I would need to add another Power supply to manage more pedals. at some point, I need to draw the line. But I would love to add a second OD, a Uni-vibe, a second Delay. I could build up a PT-Jr to go along side I suppose. Another alternative is going with a Multi-effect unit like an HD500 or GT-100. But I've never found ME pedals to sound anywhere as good as my hand selected pedals. open to suggestions.
