New Module: FET Drive

Published: 12 August 2020 12 August 2020

 

   

Hello, Effects Fans!

Yes, it is once again time to announce a new GT effect module.  Today we announce our new FET Drive module.

The GT FET Drive compares to the Wampler Plexi Drive.  It gives you three cascaded stages of tubey, high-gain JFET transistor drive.  It is meant to serve up the tone of a cranked Marshall Plexi, one of the iconic amp tones of all time.

It is a simple design, sporting the standard Volume, Gain, and Tone controls.  Bass Boost and Treble Boost switches give you a bit more control over the levels of treble and bass.  At low Gain settings you can get a not-quite-clean boost.  It also cleans up pretty well if you back off your guitar volume.  The treble and bass boosts have a significant impact in their range, including some "nearby mids".  With the Gain and Volume up, it has a nice feel.  Feedback is available in abundance, but the gain doesn't go over the top.  It stays in control without squealing and breaking down with normal input signal levels.  Also, with Gain and Volume cranked, you'll get a little bit of noise, as you would expect.  It is comparable to the noise level of a cranked Marshall.  Fully cranked it has perhaps a smidge less of the high-gain hair than some of our other Marshall-esque modules.  It is roughly comparable to our PlexiSS, GTM-45, 12K68, and Prime Minister modules.

You can see the details about our FET Drive module at: FET Drive.  Or look for it in the Amp Sim Modules section under Products -> Modules -> Modules By Type.
