Hi. No, I haven't tweaked your pack amps, just added some delays and reverbs. I have just connected AX8 to Matrix power amp and than to Q12 passive monitor, loaded your amps... I have to use hi-low cuts in the cab section, otherwise the sounds are not usable in a gigging volume with my band. I am just wondering why there is no hi-low cuts used in your presets? I mean at low volume they sound great on studio monitors, but in a gigging volume there is a lot to do... Oh, and I know about this "fletcher-Munson"... [/QUOTE] For the record, the creator of the "Naked" amps is @austinbuddy , not me. I was just relating how, to me, they seem to be well dialed in for live use. I mainly play through flown Electro-Voice mains and moderately-price Electro-Voice wedges in a moderately large venue. The presets I've played live have been winners in that environment, and they do a passable job in a quiet studio. Note that the guitar can make a huge difference in how it sounds. Example: one of the Naked presets gave me +8 dB on the VU meters, even though try're dialed in at 0 VU. I tried another guitar, and I got close to 0 on the meters.
