Just put together this set up and I'm really impressed on the tone this rig gives me on stage, not to mention using the RC-4 foot pedal for the presets and built-in tuner. I've giged using just one cabinet for a while and I believe this is my best set. I've been a big fan of Carvin products and had their R1000 head and the 4x10 and 18" cabinet and it sounded awesome. Now, I prefer the weight savings this affords me but still have that power needed when needed. I highly recommend TC Electronic bass gear! Any other fans?
