I had one of the early AI Clarus heads for a while, and found it wonderful for Fretless Acoustic Bass Guitar (Rob Allen MB2), but not very good for fretted electric (tubby low end and not enough 'zing' and punch). I like a punchy sound with plenty of high end and play active basses with bright round wound strings. Has anyone tried both the Clarus and the new Focus. From a previous thread, I understand that the Focus is totally digital (digital amp and switching power supply). Is the Focus more 'modern sounding and more appropriate for fretted electric bass than the Clarus?
