Maybe you guys have some ideas for me.. I have a pre-fender SWR Super Redhead. I love the tone of the amp, its awsome, but I just can't get volume and low end out of it, at leaste for performance volume, with out feeling like the amp is about crap out. Even when i have my bag end s15d hooked up to it, it feels underpowered... Is this common? I feel like I could even get more volume hooking a nice head up to the s15d. Maybe you guys have some ideas or some experience with the redheads. As I mentioned, I love the tone of the amp, I just feel like I'm gonna blow it up everytime to try and compete with my drummer for volume... Thanks!
