For those of you soloists and duos that are looking to expand your sound even more, now that you have drummer at your feet, you might consider the Electro-Harmonix B9 organ pedal. I just purchased one and if you’re wondering, it works fine with an acoustic guitar. In fact, in my case, it works great with a 12-string acoustic. Now when I perform “Thank You” or “Your Time is Gonna Come”, I have a Jones as well as a Bonham behind me and “Us And Them” sounds amazing! It really sounds like an accompanying keyboard rather than your guitar going through a filter, as the “keys” switch on and off based on note volume levels. Add to this a guitar-driven vocal harmonizer like the TC-Helicon Harmony Singer and you’ll have a huge sound!
I tried it and sounds pretty cool but only a 1 trick pony and I prefer my roland synth for tons more sounds~jmho
Yeah in my case I was really only looking for 60’s / 70’s organ sounds and only in the background (it’s so easy to over-do the tech 
) The newer model, the C-9 adds more sounds, meletron and others. but I also didn’t want to over-spend and be disappointed. Stones songs like “Torn and Frayed” or “Shine a Light” also sound great with this pedal, as does “No Woman No Cry” , “Breathe”, and “Brain Damage”
