Well it seems I'm getting mixed signals for comments on a new head. These are the final choices: Eden WT-400 or WT-500 Ampeg SVT-3pro Mesa m-pulse 360 what i'm looking for is enough headroom to clear an acoustic guitar and drums. i don't need to be blasting. also tone wise i want a more warm natural sound instead of my SWR which is good but its not doing my pentabuzz justice in a way. please offer suggestions, thanks!
