From the vendor
An awesome improvement, it cuts a lot of the low-end and makes it more usable.
Build notes
The bias voltages are a starting point. You can tweak all three stages to taste, doing it by ear you’ll hear when it’s growling and when it gets softer. There’s a lot of range possible, so find what works for you!
