Einstein is a small sized head with four sounds located in two channels. It switches without midi, but comes with two loops and a recording output, that can be hooked directly to your mixing console or PA. It has two switchable master volumes, who expand the sonic abilities further.
The Herbert can serve up a wide range of tonal colors and textures courtesy of its three channels, each of which is voiced differently and optimized for a specific range of gain and tones.
This amp sounds like nothing else I have heard. I chose this amp because I am a massive Hetfield fan and I have just sold it because the only Hetfield tones you will achieve with this amp are "Death Magnetic" tones!
4 channel inserts, serial and parallel master loops. Bass, mid treble in each channel, deep and presence in the master section. 4 individually voiced, all tube pre-amps. Clean, crunch, heavy and lead.
