u-he Twangstrom Spring Reverberator Plugin

Here's what u-he have to say: 

Twangström: Shake, Rattle, and Roll. A flexible spring reverb box-of-tricks. If you're familiar with Bazille, you might already have come across its built-in spring unit. We took that one, then modelled two more reverb tanks, paired it with drive section, filter stage, envelope, and mod matrix. It emulates a hand-picked selection of the most popular units you will find in classic guitar and instrument amplifiers, recreating the odd character of real springs.

Features: 

• Shakeable springs
• 3 different reverberation tanks, inspired by the most popular ones built in the guitar & instrument amps that made rock 'n roll
• tasty drive & tone stage for heating-up and colouring the sound
• multi-mode filter, with variable type blend
• four-flavours envelope stage, picking up the signal from either input, output or external sidechain
• LFO module, 8 different types & waveforms, variable time base & syncable
• comprehensive modulation matrix, for realtime control of all the parameters
• independent input and feedback routing options allow all possible stereo or mono combinations
• 76 factory presets, NKS-compatible
• UI instantly resizable from 70% to 200%
• custom remote control via MIDI CC, 14-bit resolution option
