Hello all, I have been searching the threads for info so I apologize if this has been already been answered. I am a new member and currently in the "practice with feeling" stage of bass playing. Currently using the Hal Leonard Bass Method Book1. My bass is a Jackson Professional 4-string and a 15watt Johnson amp, perfect for practicing at home. My question: when I decide to experiment with effects pedals and such, is there a minimum leval of wattage that one needs to be able to get the effects through the amp? I'm not looking to invest in amps fit for a stadium or concert hall, but would a 50 or 100w be a good jump? Thank you.
