Version 2.0.10 (September 5, 2018)

New Amp Models (2)

  2. Acoustic Sim: Six distinctive acoustic instrument simulations for transforming electric bass with great-sounding acoustic tone. Paired with Acoustasonic preamp for additional tone shaping.

New Effects (7)

  1. Modulated Small Hall Reverb: Builds on Fender’s Small Hall Reverb by 
adding lush modulation to internal reverb structure. Added high- and 
low-frequency cut controls further expand creative possibilities.
  2. Modulated Large Hall Reverb: Similar to Mod Small Hall Reverb 
above, with modulation added to internal structure of Fender Large 
Hall Reverb.
  3. Mythic Drive: Inspired by the ’90s-era Klon Centaur; a 
germanium-diode overdrive with smoothly subtle color and character from a complex gain structure that blends clean and distorted signals without significantly altering guitar tone.
  4. Sustain: Inspired by the MXR M-163 Sustain, a rare 1980s compressor pedal with a particularly strong compression effect and a short attack time.
  5. 2290 Delay: Inspired by the TC Electronic TC 2290 delay, a 1980s studio-standard digital delay still sought after today for its crisp repeats and versatile panning/modulation options.
  6. Memory Delay: Inspired by the Electro-Harmonix Deluxe Memory Man, a late-’70s “bucket-brigade” delay pedal that imparts distinctive character to repeats and modulation.
  7. Metal Gate: Inspired by the ISP Technologies Decimator II G String pedal. Especially ideal for high-gain metal, with a very fast attenuation curve.
