Thunderbolt30 GEN2


The Greer Amps Thunderbolt30 is our take on a classic sound.  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 jazz and 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.

Thunderbolt30 GEN2 features a new logo, some small circuit tweaks that Nick has always wanted to include (it still has that awesome TBOLT tone, though!), and a combination of Heyboer and Mercury Magnetics transformers that are custom wound for Greer Amps.  Some specific units might have both transformers from either company, we tune all amps to have just the right sound.
