A new guitar amplifier

Eric Barbour started a company called Metasonics. Metasonics is dedicated to pushing blasting through the envelope when it comes to vacuum tube signal processing. With products like the Scrotum Smasher, the Wretch Machine, and the Alien Butt Probe it was no wonder that their flagship Guitar Amplifier would get an interesting name. Meet the G-1000 Fucking Fucker Guitar Amplifier:
A Truly Radical All-Tube Guitar Amp.
There is nothing like the G-1000. Not even vaguely. It is arcane and radical. It is 100% vacuum tubes, from input to output. It contains 100% new-old-stock (NOS) tubes. Types never seen in guitar amps.

The G-1000 consists of two totally independent amplifiers, with very different preamp sections. One channel is called the HAPPY channel. The other is called the ANGRY channel.

For damn good reason. One sucks your face, the other gnaws your foreskin off.

The HAPPY channel is a more-or-less conventional instrument amp. It has plenty of gain and distortion (if desired), it has a conventional guitar-amp tone control section, and it has reverb. Everything else about it is DEVIANT. It has a PHASE control, which allows mixing of normal and inverted signals�or it may be adjusted to cancel out the original signal and pass only the distortion products....and, it's all made of unusual tubes. Mostly pentodes, ha ha ha.

The ANGRY channel is well-named. It is designed for instability and raw, berserk distortion effects. It, too, has typical guitar-amp tone controls and reverb. It uses a 6BN6 and two remote-cutoff pentodes. Ask your mother what those are. She's already tasted your foreskin anyway.

Despite the identical output stages of the two channels, they sound TOTALLY different. In ALL settings.

The output tubes are 6BK5s. Obscure, yes, but great and forgotten. Phase inversion is done with 6GU7s. Various types are used throughout the preamp stages: 6AU6, 6BJ6, 6CB6, 6BN6, 5BQ7, 6AK5, and others. No 12AX7s, of ANY brand. How many tubes? TWENTY-THREE tubes in total. Including eight 6BK5 outputs. It might be the most complex tube guitar amp available today....

The output tubes are in a special self-balancing, self-biasing circuit. It is unique to the G-1000 among guitar amps. It does NOT NEED matched tubes, nor is any kind of bias adjustment needed. Output power is 15 watts per channel, and two speakers (or a stereo speaker) are needed.
Eric's design skills are legendary so this will be an amazing amplifier. Built one-off by hand, price is $5,000 -- worth every penny! Posted by DaveH at January 18, 2008 8:05 PM
