Twangstrom

u-he

Twangström is a spring reverberator that emulates the mechanical character of classic guitar and instrument amplifier reverb tanks through physical modeling. It recreates the distinctive 'chirpy' resonance and metallic warmth of real springs with adjustable tank types, drive stage, multimode filter, and comprehensive modulation controls. Unlike impulse-response-based reverbs, Twangström simulates the actual physics of spring vibration, allowing real-time parameter control for evolving, unconventional textures.

Key Features

013 reverb tank types inspired by classic guitar amplifiers (Type 4, Type 8, Type 9)
02Physical modeling of spring mechanics with controllable Tension, Decay, Density, and Coupling
03Shakeable springs with Twang control for manual or modulated excitation
04Drive and Tone stage with dual-stage soft-clipping saturation
05Multimode filter with variable type blend (lowpass, highpass, notch, bandpass) and stereo offset
064 envelope modes (Envelope Follower, Attack/Decay, Attack/Release, Cyclic) with sidechain support
07LFO with 8 waveforms (sine, triangle, saw, square, stepped random, smooth random) and syncable time base
08Comprehensive 3-slot modulation matrix with curve, quantize, rectify, S+H trigger, and slew limiter
0976 factory presets and NKS compatibility
10Resizable UI from 50% to 200%, 14-bit MIDI CC resolution

Things to Try

  • 01Modulate Shake with the envelope to excite springs on transients, creating more lively reverb
  • 02Set Tension to -33% to simulate classic amp hardware delay times (33ms, 37ms, 41ms)
  • 03Use Bright mode when extra sparkle above 5kHz is desired, noting the ~30% CPU increase per instance
  • 04Apply subtle continuous Twang modulation to make the reverb sound more lively
