The Four Aces is a unique push-pull Class-AB output stage using a 6SN7 Octal preamp tube as a triode output tube. Possibly the coolest home practice, studio recording, and maybe even small gig amp ever! The amp features two channels. Channel one is a single volume control non-master channel with high, mid and low controls, a gain boost which works while keeping the tone controls active, and a digital reverb based on the same technology used in the Good Verbrations® pedal. This provides a fully adjustable lush reverb, with level and decay controls. Channel two has its own input gain control and output master volume. It shares tone controls with channel one, as well as the tone controls being active with the gain boost activated.
The Four Aces is based on two 12AX7 preamp stages and a 12AT7 driver stage. A surprising amount of clean headroom is available before the output stage begins distorting with a sweet yet warm and natural overdrive. Its tone provides a cutting rock edge, filled with harmonic richness and chime. The circuit design also is “attenuator friendly”. The Four Aces and its higher-powered siblings the Lucky-7®-II, Blackjack 21®-II and Full House®-50 have a preamp stage inspired by our ODS® and TDS® designs, which allow clean-to-mean from the guitar volume control on both the clean and dirty channels. What’s great about this power level, is that you can use the amp as a single channel amp with reverb, gain boost, and natural amp overload, as a single channel high gain amp (using the overdrive channel and the guitar volume to control everything), or run it as a traditional channel switcher amp!
