15 watt gain machine! Cathode biased Dual EL84, two 12AX7s, and a 5Y3 rectifier. One volume, one tone, no frills! When we decided to do a minimal headroom dual EL84 amp, we weren't messing around. This amp does things with EL84s that you never thought were possible. With a Strat, this amp has some nice headroom with just the right amount of hair to the tone. With a pair of humbuckers or P90's you better take a step back! It says 15 watts, but no one told the NTG15 that! Tons of vintage style gain on tap, just 2 knobs. Grip it and rip it!
