In a band with a pretty silent stage (e-drums and everyone on a decent IEM), the need for amps is not as big as it used to be. The guitars run tiny 5W tube heads with 112 cabs and I bring my cab more or less only to enhance the IEM experience for me (and the drummer) by adding some vibration to the stage and make my pants flap. That shifted my attention a little bit away from amplifiers as such, since it became somewhat marginal what gets pumped into the speakers and a lot more important what gets sent into the XLR cable on stage. I totally dig the sound of tube amps, but always shied away from the 40kgs 300W heads. What do you guys use to send the perfect signal to IEM ?
