Introducing the PakVerb (PakClean F Pak)  Based upon the 6AQ5 18 watt formula, the PakVerb delivers the ultimate in clean American blackface type tone.  The 3 band tone stack gives a familiar bouncy low end and articulate treble with a deep mid scoop. The bright switch adds sparkle to humbucker guitars, and the tweed switch thickens otherwise skinny single coils.. This is the AMERIKHAN version of the 6AQ5 Pak amp flavor.American type classic clean soundVolume Treble Middle Bass and reverb controlsDigital Reverb closely modelling a spring18 watts class A/B at 5% THD(2) 12AX7/ECC83,  (2) 6AQ5/6005Bright switch and tweed switchReverb and tweed footswitchable100% handmade in the USA7 day money back guaranteeThe new blackface style FPak does a bit better with an open back cabinet. Again a 1x12 or 2x12 is best here. The looser bass response and familiarity with the open back speaker design is beneficial in this case. Speakers that are more open midrange and tighter controlled bass response are best.  Examples: Jensen, Texas Heat, EV, Altec, etc
