The newest model in the Guytron lineup, the new GT40 is now shipping!  I completed two of the new GT40s this week.  I built a head and a combo.  These two amps were intended as saleable prototypes meaning that they were built entirely with production parts but being the first to be so, they would be subject to some testing and evaluation before being approved for sale.  In particular, I had to do some testing on the new GT40 transformers.  They worked great so we have placed an order for transformers at a production level and hopefully within 3-4  weeks we’ll be building GT40s with more regularity.  This first combo (Serial #001!) is going to a customer in Kansas City, MO while the head is going to a customer in France!  Bon Jour Nicolas!  Here are a couple photos of the head.  I’ll post more later.

Here are the specs for the new GT40 (subject to change of course):

  • Power tubes – two El34s for roughly 40 watts
  • Preamp tubes – four 12Ax7s
  • Preamp – Guytron two channel preamp (protected by patent #6111961) with Gain, Tone and Volume in each channel.
  • A channel has the classic Guytron clean tones with the tone stack before gain for those classic clean to low-gain overdrive tones.
  • B-channel has the tone control post-gain plus it has two extra gain stages for a range of tones from a pushed clean to a raging all-out hot-rodded superlead distortion tone.
  • Transformer-driven balanced line out, post-output transformer for a natural amp sound to the mixing board or to your slaved high powered amplifier.
  • HLBâ„¢ microphone output (on combos only).  The Sennheiser microphone element is permanently mounted in front of the speaker exactly where it should be mounted.  The output is in a small panel on the rear of the combo where you can quickly and easily plug in your mic cable.  No fumbling with mic stands and microphones, and no dealing with the variance of mic position night after noght.  With the HLBâ„¢ the mic is always in exactly the same spot every night for a consistent mic’ed tone every time.
  • Lighted top panel, lighted back panel, lighted logo and as a matter of fact, there is so much light that the whole inside of the amp is lit so you can see where that guitar cord is hiding.
  • front panel lighting changes from blue (A-channel) to red )B-channel to instantly indicate which channel you’re on.  Of course it will be pretty obvious from the gain and the attitude but everyone will think it is very cool.
  • Guytron Bigtoneâ„¢ 55 speaker in the combo.

All Combos and heads will be shipped with a custom embroidered Guytron cover and heads will als0 ship with a Guytron Bigtoneâ„¢ speaker cable.

Send me an email if you are interested in this new GT40 or just to talk.  I’d love to hear your opinions.
