I've been playing semi-professionally for 45+ years. In my early 60s, I "downsized" to a PF500 head and a wonderful Avatar Neo 210 cab (which I am keeping). Like many have reported here and elsewhere, my PF500 has been--of late--problematic (cut-outs, slow turn-ons, etc.). Part of me wants to stay with the great lightness of class D micro amps (thinking BX500), whereas a little voice in my ear is saying: get the old-style, solid Hartke HL500. I am well aware and familiar with the EQ differences (just like my old bassman EQ) and the different control layouts. I'm thinking the LH500 would be a more durable and reliable unit, and I like the simplicity of the controls. And yet, the lure of "featherweight" amps persists (Fender's newer 500 watt entry is tempting). I play in a lot of sketchy electric venues here in SW FL and wonder if that could be a factor with the class D amps cutting out and generally frustrating me. 23 lbs. is not an obstacle, as I lift way more than that every morning. Any thoughts?
