I have the house to myself for a few days so I decided to plug in and play over some chord changes using my Dito Looper. Brutal. If you wanna test yourself to see how well you can play over changes, it's a good way to hear some ugly truths. I'm not saying it's not fun...I'm just saying it's a good way to assess your progress, good or bad. Edit: I use a Kealey Tone Work Station for dirt and compression, Boss Waza Craft for Delay, and Hughes and Kettner Grand Meister 40 for amplification and effects such as reverb, chorus, flange, phaze or tremolo.
