Agave Audio Introduces the Cumbre Preamp

A point-to-point handwired boost designed to drive the front end of your amp.

Albuquerque, New Mexico (January 5, 2016) -- Agave Audio’s Cumbre Preamp is a point-to-point handwired boost designed to drive the front end of your amp. First, use the normal channel to dial in the perfect edge of breakup/rhythm tone. Need a little more drive after that? No worries, hit the Boost when it's time for your solo! Even without adding extra gain, your tone will sound fuller and more present. Due to its simple nature, the Cumbre Preamp is incredibly flexible and integrates seamlessly with any guitarist’s rig.

Cumbre Preamp highlights include:

  • Point-to-point handwired construction
  • Single JFET transistor for tube-like tone
  • Dual channels for multiple gain options
  • 9 volt, center negative (not battery operable)

Price: $199

We’re almost finished with the aging process on our project guitar. Let’s work on the fretboard, nut, and truss rod cover, and prepare the headstock for the last hurrah.

Hello and welcome back to Mod Garage. This month we’ll continue with our relic’ing project, taking a closer look at the front side of the neck and treating the fretboard and the headstock. We’ll work on the front side of the headstock in the next part, but first we must prepare it.

Diatonic sequences are powerful tools. Here’s how to use them wisely.



• Understand how to map out the neck in seven positions.
• Learn to combine legato and picking to create long phrases.
• Develop a smooth attack—even at high speeds.

Knowing how to function in different keys is crucial to improvising in any context. One path to fretboard mastery is learning how to move through positions across the neck. Even something as simple as a three-note-per-string major scale can offer loads of options when it’s time to step up and rip. I’m going to outline seven technical sequences, each one focusing on a position of a diatonic major scale. This should provide a fun workout for the fingers and hopefully inspire a few licks of your own.
