"The Howler is a warm sounding distortion box that deals out some very tube-like tones over a wide gain range -- from soft breakup to super saturation... what I like most about the Howler is its abundance of smooth sustain, and the fact that you don't have to jack the Gain control all the way up to get it."

Based on the Maven Peal Sag Circuit, the Howler is built with the same audiophile-quality parts as Maven Peal amps. As a result, the Howler has a very transparent sound and an extremely low noise floor. The Howler gives you new and unique controls that literally wake up your strings with any amp you're using -- tube, transistor or modeling.

Use the Howler as a:

  • Clean/Fat Boost
  • Clean Treble Boost
  • Jazzy/Tweedy Dark Compression
  • Clean Buffer for Driving Long Cables and Difficult Loads
  • Clean Buffer with Optional Added Sag
  • Overdrive
  • Clean Treble Boost/Overdrive and Added Recording Warmth

Use the Howler to:

  • Add warmth to modeling amps and pedals
  • Add warmth to recordings
  • Increase your amp's ability to cleanly sustain
  • Push your amp into singing sustain
  • Add high end boost for leads
  • Transform your clean amp signal to crunchy rhythm
  • Add a new palette of colors without radically changing your amp's tone

The Howler gives you:

  • The Peal Knob
    Identical to Maven Peal's Sag knob, the Peal knob literally allows you wake up your strings... or not. With the Peal knob turned up, your strings wake up and blossom. At first, there's an initial delay and compression accompanied by softening of tone. As you hold the note, the compression goes away and the note blooms like a cranked tube ampifier.

    With the Peal knob turned down, your strings become immediate, tight, bright and punchy.

    The Peal Knob is very interactive with the Gain Knob. You can add the saggy, compressed feeling to your tone without overdriving the pedal. At low settings of Gain, you will need to set the Peal knob at higher settings to get the pedal to start sagging. The higher the Gain setting, the lower you will need to set the Peal knob for an equivalent amount of sag.

  • The Gain Knob
    At lower settings, the Gain knob will simply adjust the level of the signal going through the Howler. The Howler has an very large amount of clean head room and you will need to turn the Gain knob up pretty high (2:00 or more) to get some overdrive going. The Howler uses unique overdrive circuitry developed by Maven Peal and produces a smoother and more complex tone than traditional stomp boxes.

  • The Tone Knob
    The Tone knob lets your guitar scream from high end boosts to bluesy darkness, and everything in between. At 12:00 on the Tone Knob, the tone shaping circuitry is essentially bypassed, letting all of the guitar signal through (including the bass).

  • The Volume Knob
    The volume knob allows you to adjust the overall signal level going out of your Howler and into the rest of your gear.

  • Top Input and Output Jacks
    Placed on the top of the pedal box to give you more room on your pedal board, the Input and Output Jacks are both buffered. The buffered Input does not load down your guitar or other gear. The buffered Output allows you to drive long cables or hard to drive effects (like a traditional Wah) with ease.
The Peal and Gain knobs -- Controlling Bloom
Add that saggy, compressed feeling and smoothed out high end of a cranked amp to your signal chain via the Peal knob, which is uniquely interactive with the Gain knob. At lower Gain settings, set the Peal knob at higher settings. The higher the Gain setting, the lower you will need to set the Peal knob for an equivalent amount of sag.

The Peal knob behaves differently with different guitar volumes and Gain knob settings. At the lowest setting, the Howler is as tight as your amp and doesn't add sag to your signal. As you increase the Peal knob setting, the Howler adds initial compression followed by a bloom (where compression tapers off) opening up the Howler's tone -- responding much like a cranked tube amp. At higher Peal knob settings (and especially with added high Gain settings), the Howler compresses the signal and stays compressed without a bloom. For an equivalent bloom response, lower the Gain as you increase the Peal.

You do not need to push the Howler into overdrive to add sag to your signal. And even when you use the Howler as a clean buffer, you can add sag to your tone.

Other Cool Features

  • True bypass switching
  • Groovy blue LED at the tip of the moon
  • 18Volt Power supply for increased clean headroom -- no batteries to clutter landfills, or go dead on you (and with the Peal knob, you don't need "old batteries" to make the Howler sound great)
  • Changable, socket-mounted Op Amps for different flavor tones
  • Chassis mounted pots and jacks, hand-wired to the circuit board
  • Audiophile quality parts, same parts used in Maven Peal amplifiers, including military spec circuit board, Orange Drop and Nichicon Capacitors and High Wattage Metal Film Resistors
  • Metal Switchcraft jacks
  • Standard power jack
  • Classic stomp box Op Amps
  • Powder coated, RF shielded die-cast aluminum chassis

What is an Impact Pedal?
An impact pedal is a new category of pedals that incorporate Maven Peal's patented Sag Circuit power supply design features into a small, compact pedal. Impact pedals literally impact the way your guitar responds to your touch -- all without negatively impacting your neighbors, family, band members and your ear drums!

    This pedal [the Howler] rocks! It really delivers the warmth and complexity that is ever elusive from any other pedal I've tried! It is the ultimate lead/boost for my live setup.

    It [the Howler] has surpassed my expectations to the nth degree. Not only is the howler dead quiet, it is also completely transparent to the original sound source. I can't speak for everyone but personally my ideal when it comes to tone is "sustain without distortion". Now ,obviously your going to get some distortion when generating sustain, but the minimum distortion level created by the howler is nothing short of amazing. When plugged in front of my 1964 fender vibroverb, and I imagine any vintage non master volume amp, the notes sing and sustain for days. Add the sag control, and you have complete control of attack,sustain, gain, and volume. The same holds true for my more modern amps as well. The bottom line is, you have created a pedal that is going to be the gold standard as soon as the rest of the world catches on.


    I tried it [the Howler] on my Zeeta. It added lots of sustain that is a plus when I use a slide which was a pleasant surprise I did not anticipate. It also added some deeper growl thanks to the gain.

    My friend has a Mesa Boogie Express 50. The impact of the pedal and especially the peal knob was much more noticeable on his amp. He really liked the Howler. My other friend has a Hughes and K. 50 watt combo.
    Similar results from the Howler.
