BSRI Audio (Baltimore Sonic Research) EVT (Envelope Controlled Tremelo)

One of the more unique Trem pedals i've seen.  Dynamic and unique how the speed responds to your strumming and pick attack.  

See demo for some cool sounds.

EVT is inspired by, but not a clone of, a little blue Japanese tremolo pedal I owned in the early 2000s that had no traditional speed control. Instead it changed the rate of the modulation based on the strength of your pick attack. I foolishly sold it in a pedal purge and haven’t been able to find one since. With EVT I set out to recreate that envelope tremolo functionality alongside a traditional LFO mode that delivers lush vintage optical tube amp tremolo. EVT features a high headroom Class A preamp and, in true early 2000s boutique style, doubles as a beautiful clean boost with the depth all the way down.
