I used one for years, and I really loved the tone. Like many folks, I had reliability issues; it broke down on the gig. I remember the tone so fondly, I'm actually tempted to consider a new one again (with warranty). Am I crazy? Fool me once, shame on me? Have they become more reliable? Do I remember the tone correctly, or am I looking back with rose colored ear buds? P.S. I use an Aguilar TH500, which I quite like, but it doesn't sound as good as the ABM500 in my head.
