I got this cab (ampeg 410HLF) hoping that with my 400+ would produce some damned clean sounding bass at high volumes. Maybe I just suck at dialing in good tone, but im having some problems. At higher volumes, specifically after hitting the E string, I hear a loud high frequency sound. So I lower the bass and the volume and it sounds nicer, and the sound goes away. Is this my cab about to give in? maybe a horn problem? Also, the cab sounds very boomy. Would a compressor do the trick? I am very afraid that I am going to blow this cab out with my head. Mesa says its rated at 500 watts RMS but people on here doubt that. I personally don't think its really 500 watts RMS as I don't have nearly as much headroom as I thought I would have had. Would a second 4x10 HLF cab do the trick? I just want a nice clean sound while its loud. I feel like something is wrong! Is there seriously a possibility I could be getting better tone out of my B2R and an SVT 15e?
