Like taking a blanket off of your cabinet. 

The HD is a multi mode Harmonic order focused overdrive, offering true boosting of the entire harmonic range of both your guitar (bass as well). 

It features 3 clipping modes:

Hybrid Germanium, using a selected rare spec NOS diode from my collection I have amassed over the years.

Schotky, for a more compressed but smoother sustained tone, great for leads. 

Full diode lift for the raw op amp to shine, which is louder. 

It also features a post tone voicing control to allow you to tame a bright guitar, or brighten a darker guitar.  

Tone wood is real, dont allow people to tell you otherwise, theyre wrong. 

This product is hand assembled and hand soldered with through hole components. 

It has PCB mounted pots and switches. 

This product is not made to be used with a budget brand power supply, so that one spot/ daisy chain isnt good enough. 

We suggest, and use CIOKS, Strymon and Walrus brand power supplies. 

You should too.

This product is also purposely made to not interact well with modeling/ profiling devices. 

We do not support those childrens toys, we make hardware for use with real amps and cabinets, not people tethered to their computers all day. 

All sales are final. 

No refunds are offered.
