Workhorse Head

from 1,299.00

The Workhorse:

This amp is our homage to the working guitarist.  We've priced it with working players in mind, as well. 

A compact, simple, effective tool for the player who likes it basic, with nothing getting in the way of your tone. This amp is an extension of your guitar.

Even the 20 has enough power to cut through on any stage (and with any drummer).

It's a perfect pedal platform, or you can use it as a "crank it and go" extension of your guitar, controlling all those lovely shades of clean to overdrive with your guitar's volume knob. Peg the Gain and clean it up from your guitar! 

It has a mid 60's American inspired preamp giving a wonderful range of clean into dirty tones that take on a British flavor as you crank it up, a responsive tone stack, and tons of touch sensitivity ("feel").

An incredible amp for blues, rock, or country, and also a perfect platform for pedals

Controls are: Gain, Bass, Middle, Treble, Volume, and a Lean/Phat switch that changes the low end and gain structure. 20-100 models feature a post phase inverter master Volume. 

The basic Workhorse features our 10 watt singled ended Class A, cathode biased output stage using any octal power tube under 30 watts (we prefer a KT66!) and a 5y3 tube rectifier.  You can also run a pair of 6v6s in parallel single ended as well, just ask us and we'll include a second octal socket!

The Workhorse 20 has more power and clean headroom than the 10 watt version, and as you go up in power, the headroom increases. That means more available low end, and a creamier, smoother crunch when cranked in the 20-100 watt versions.  

The higher wattage amps feature our loud and clear push pull output stage via two 6v6s or KT66s, which yields great headroom for clean tones, and smooth dirty tones.  Our excellent post phase inverter master Volume allows you to take the edge off without sacrificing tone, and if you turn it all the way up, it's out of the circuit, giving you non-master volume response.  Soundguys love this knob. 

This amp is handmade and hand wired on turret board construction, one at a time, in Columbia, Missouri.

This is a custom build!  You choose the colors!  Upon adding an amp to the shopping cart, you'll be asked to choose your tolex, piping, and grill cloth colors.
