The Groove Tubes STP-G II Studio Preamp is a rare and versatile rackmount amplifier known for its rich sound, and is perfect for audio engineers, guitarists, and collectors seeking analog warmth and great tone while silently recording directly into the board or an audio interface.

This 90s rackmount features 25 Watts of power, 8 Ohm speaker output, line out with control for amp slaving, parallel effects loop, speaker emulator for direct recording, preamp level control with a -10 db Pad, EQ with added "Brite" sound and mid boost, power amp controls, and controls for the speaker emulator. It uses two EL34 tubes and four 12AX7 tubes.

From the original owner's manual:

The GT Electronics Studio Tube Preamp for Guitar (STP-G) can plug directly into the recording console and deliver true power tube tone and distortion, drive any slave amp for stage use, or can even hook up to a guitar speaker for small clubs or practice. The purpose of this manual is to acquaint you with the controls and the many possible sounds available to you.

Simply stated, this is a complete 25 watt all tube guitar amp with a classic design that is similar to many of the old Fender amps you already know. We’ve added an extra stage of gain and a selectable mid-boost section to get that “heavy metal” overdrive sound, but you can switch these off to return to a classic “clean ’n crunch” sound typical of an old Fender or Marshall.

What makes this preamp unique is the additional circuit we’ve added called the Speaker Emulator (patent pending) which interfaces the 25 watt amp to the mixer input. In other words, the Speaker Emulator turns the amp into a preamp. This means you can get the sound and feel of a 25 watt tube power amp directly into the console for recording…without a microphone or an isolation room. The STP-G delivers crystal clear rhythm sounds or searing lead tones, and it gives them directly into your mixer without the typical high volume levels that make recording guitar difficult and impractical. Naturally, the STP-G can be used in live music situations and go directly into the PA mixer. Imagine how well the vocal mics will work without those high volume levels bleeding into every mic on stage, and how good the guitar mix can be when it’s totally isolated from the other instruments!
