The Arborist

Discrete transistor boost and overdrive

The Arborist V2


The Arborist was born as the silicon side of the former Giganteum Drive, offering excellent discrete transistor tones to color your sound and provide an awesome base for light drive and gain stacking. 


For The Arborist V2, we went back to the drawing board and implemented a lot of feedback we got from you all! The second version retains the original tones of V1 at certain settings, but has way more variety and flexibility. We've expanded the tone stack to include independent passive treble and bass controls and we've added a versatile 3-way voicing switch with 3 distinct modes: smooth, dynamic, and comp. They are based on a unique germanium feedback/diode clipping arrangement and are balanced enough to switch on the fly, but unique enough to allow for extremely fine tuning by interacting with the other controls. 


  • Switchcraft Jacks
  • High quality Taiway toggle
  • Premium Gorva true bypass footswitch
  • Enclosure printed and milled in the USA
  • Hand wired and assembled in California
  • Standard negative ground power 
  • Improved noise floor
  • Improved RF filtering
  • Various small circuit stability improvements
  • More stable biasing 
  • Added low-pass filter on output to reduce harsh highs


  • Top-mounted jacks, input on right, output on left
  • True-bypass stomp switch is on/off, indicated by LED
  • "Volume" controls the amount of output (a lot)
  • "Gain" controls the gain of the dual transistor stages for tube-amp like overdrive at reasonable volumes
  • "Treble" and "Bass" controls work very similarly to the famous Fender Bassman 5f6A tone stack. They are very interactive and allow for fine tuning of highs and lows in the different voicing positions
  • 3-way voicing toggle to change clipping characteristics


We always recommend isolated power supplies. If you daisy chain effects on one supply or use a low-quality product, you may inject noise, ripple, ground loop hum, etc. This effect requires 9v, center negative power. In other words, the industry standard power supply.  Current draw: 2.6mA
