The Greer Amps THUNDERBOLT 30 is our take on a classic sound.  This is our best selling amp!  Blending early "AC" type, "JTM" type, and M*tchl*ss type tones, this amp is a great sounding amplifier.  The Thunderbolt 30 is used by players in every genre, from blues, to rock, to country.  This amplifier features a pair of EL34 tubes, cathode biased, in Class A mode, two 12AX7 tubes in the preamp, and a 5AR4 rectifier tube.  The front control surface of the amplifier has two inputs, input 1 is higher gain, with more snap and bite, input 2 has a more rounded, softer midrange to it, with a little less gain, and more "polite" tonal range.  The two inputs are not a typical "padded" input setup, but two different channels.  Pick one, and rock the house!  The Greer Amps Thunderbolt 30 uses custom Mercury Magnetics transformers (Output transformer has 8 and 16 ohm speaker outs), and the highest quality components.
