The BSRI Floriography, which was named EVT before 2023, is a boutique tremolo handbuilt in Baltimore with an amplitude and a dynamic mode.
The dynamic mode is based on a mysterious Japanese pedal purchased (and then sold) in the early aughts by company owner David Gill, that increased the speed of the rate based on the loudness of the input signal. The 2023 version of it (i.e. Floriograph) adds an extra mode that does the same, but in reverse (i.e. the rate is decreased, the louder the input).
The amplitude mode, on the other hand, allows for regular tremolo tones, with the modulation’s speed adjustable via the Rate knob.
Since it features a Class A preamp, it can also be used as a clean boost when the Depth control is at zero.
Here’s a demo of the EVT version of it by Eric Merrow, followed by one of the latest version, by the builder.
BSRI Floriography/EVT, Builder’s Notes, Builder’s Notes
Floriography 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.
Floriography recreates that envelope tremolo functionality alongside a traditional LFO mode that delivers lush vintage optical tube amp tremolo. Floriography 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.
The 2023 update and redesign adds an additional envelope mode that fades the tremolo in as your attack decays in addition to the original mode that increases speed with increased attack.
