I had none a few months ago and started with a tuner pedal. I purposely bought a Pedaltrain Mini to ensure that I can use no more than five pedals, which would include the tuner as well as the wireless I recently bought. Counting those two, I now have ten pedals, so my PT Mini plan seems to have failed almost right out of the gate.
I'm also apparently in denial because I haven't replaced the Mini yet. It will be interesting to see how long it takes me to move from the denial stage to the acceptance stage, get a PT Grande, and move forward from there.
