My ABM300 has managed heavy gigging for 7 years, being pushed hard I should add. Has needed nothing more than a minor service and a preamp valve. No lack of treble (learn to use the EQ maybe?), no fires!

No need to learn how to use the eq for the two reasons I stated, first the problem has been resolved by buying Genz rigs and secondly the amp failed so many times it got sold for spare parts
