Zach explains the importance of understanding all the elements of 'the signal chain' - all the steps between your acoustic violin and its amplified sound.

We'd love to hear what you do with effects on your string instrument. Post a video of yourself playing in this course's exclusive facebook group - Improvise & Groove on Strings

Lesson transcript:

Understanding Your Amplified Sound

It all starts from the sound that your pickup is making. That is the bedrock of your amplified sound. There are various things you can do to enhance this sound:

1. Choose the Right Pickup

  • Get the best pickup possible for your instrument.

2. Use a Quality Preamp

  • A preamp can greatly enhance the signal coming from your pickup. This step is often overlooked.
  • Learn about the signal chain, which includes:
    • Bow
    • String
    • Bridge
    • Pickup
  • Manipulating this signal chain will drastically affect the sound produced by your pickup.

Experimentation Encouraged

I urge you to experiment with these components. Don't just take my word for it, try it out for yourself!

Recommended Gear

The Alex Preamp

  • This is the preamp made by Grace Design.
  • I've been waiting for a product like this for 20 years!

Features include:

  • Mute button
  • Boost switch
  • Fully parametric mid-range
  • Highly adjustable high, mid, and low ranges

Sound Representation

The goal is to closely represent the sound of my acoustic violin in an electric format.

  • I'm using a cleaner amplifier and sending a direct signal to you:

"That's with an effect on, whoops!"

Tonal Properties

It's important to note:

  • You will never find a pickup that sounds just like your acoustic violin.
  • Just like you differentiate between playing Mozart and Brahms, recognize the tonal properties of your acoustic vs. electric instruments.

Tips for Electric Sound

  • Roll off the high end when playing an electric stringed instrument, especially violin:

    • Sound technicians sometimes mistakenly expect a violin to sound trebly.
    • Instead, aim for a balanced tone.
  • Tame the low end.

  • Understand how your stringed instrument works to achieve the sound you desire.

Learn Your Gear

Exploring various equipment is fun, but knowing how each piece works is crucial for achieving the sound you want.

  • When selecting a preamp, inquire about settings:
    • Low range frequency
    • Mid frequency
    • High and extra high frequencies
  • Properly set the gain.

Tuning and Frequency

Know how your acoustic instrument relates to frequency settings:

  • In the U.S., standard tuning is typically at 440Hz, while in Europe, it's often 441Hz or 442Hz.
  • Learning these details is essential.

Frequency Analysis

Using recording software like Logic can be incredibly helpful:

  • Record yourself playing scales slowly.
  • Use an EQ frequency analyzer to identify pitch peaks.

This analysis will enhance your understanding of your violin's sound across the frequency spectrum, allowing you to adjust accordingly.

Conclusion

While this may seem a bit technical, it's necessary. Now, let's move on to the fun aspects, the toys!

About the instructor

Zach Brock
Zach Brock

Heralded as "the pre-eminent improvising violinist of his generation," Zach Brock is a violinist and composer whose music draws on the traditions of jazz, classical, world and popular music. Zach received his first Grammy Award in 2017 for his work on Snarky Puppy's album Culcha Vulcha. His acclaim as a bandleader has grown through appearances at venues such as Carnegie Hall and festivals like "Tudo e Jazz" in Brazil, while his reputation as a sideman has spread through his work with legendary bassist Stanley Clarke, contemporary instrumental super-group Snarky Puppy, and jazz masters Phil Markowitz and Dave Liebman. Zach has made ten recordings as a leader or co-leader and is the first violinist to record for the venerable Dutch jazz label Criss Cross. He has also represented the U.S. Department of State as a Musical Ambassador in the Solomon Islands, performed as a featured soloist for two Sundance Festival feature film scores, and is currently an Artist In Residence at Temple University in Philadelphia. In his course you will learn to improvise on the violin straight from the source: how Zach approaches melody, rhythm and harmony, and how to start finding your own voice the way he has alongside Snarky Puppy and beyond. read more
