After owning both, I found the Micro to be kind of harsh and abrasive-sounding, while the Mini was much warmer and smoother while still having plenty of old-school squelch. If the circuitry is the same, it must be arranged differently or something. I never did mess with the internal trim pot in the Micro, though.Hi Filterfunk, why not the Micro Q Tron? I thought the circuitry between the two was the same? I only have the Micro, it's ok, a bit peaky and the internal trim pot needs adjusting to your liking, is the Mini Q Tron any different?
