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.

- Dry/Wet Audio
Electric Guitar (Dry) --:-- / --:--
Electric Guitar (Wet) --:-- / --:--
Preset used: Plate #4
Simple "vanilla" reverb settings, but LFO and input volume have a subtle effect on the behaviour of the spring, adding some liveliness. Created by Rob.
Rhodes (Dry) --:-- / --:--
Rhodes (Wet) --:-- / --:--
Preset used: Floating Point
Small amounts of overdrive and subtle high-pass filter movement give the long reverb decay some colour and movement. Created by Viktor.
Acoustic Guitar (Dry) --:-- / --:--
Acoustic Guitar (Wet) --:-- / --:--
Preset used: Stanley Stutters
Apart from the denser reverb tail, this uses a dynamic tremolo on the input signal - louder signal, stronger tremolo. Created by Rob.
Electric Guitar 2 (Dry) --:-- / --:--
Electric Guitar 2 (Wet) --:-- / --:--
Preset used: Suspension Bridge
Small amounts of overdrive add some grit to the reverb tail, whose wobbly movement comes from the low spring tension setting. Created by Viktor.
Electric Guitar 3 (Dry) --:-- / --:--
Electric Guitar 3 (Wet) --:-- / --:--
Preset used: Touch of Twang
Classic 60s-style guitar, classic 60s-style spring reverb setting. Created by Rob.
Rhodes 2 (Dry) --:-- / --:--
Rhodes 2 (Wet) --:-- / --:--
Preset used: Wah Screamer
Auto-wah setting where the envelope follower moves the filter to add some funky bite to the electric piano. Very short reverb settings give the impression of a small practise room. Created by Viktor.
As a faithful emulation of a mechanical device, Twangström needs to be handled well. Many of the technical parameters are user-adjustable in real time, and these can be controlled via MIDI or using the internal LFO and envelope generator. With its multimode resonant filter, Twangström is a unique and powerful tool which can deliver highly unusual, evolving textures... especially when the signal is tossed around using the modulation matrix!
Hitting your computer won’t make Twangström shatter, so we added a twang control. This is used to shake the springs, either manually or through modulation and automation. You might think this is a gimmick for which you have no further use (apart from waking up the neighbours), but if you modulate it slightly, everything comes to life!
Twangström's reverb is based on physical modelling. As opposed to plug-ins based on impulse responses (IR), our approach mimics the physics of mechanical reverberation. By simulating the wavefront travelling through a medium, we can include all the aspects of excitation, reflection, dispersion, interference, and other audio properties. Twangström does not mimic the sonic result, but simulates the physical device. This means that all dimensions of the device are controllable in realtime, on a per-sample-basis – which all boils down to quite some power at your fingertips!
The envelope in Twangström features 4 different modes and can pick up the signal from either input, output or external sidechain. You can select between Envelope Follower, Attack and Decay, Attack and Release, or Cyclic modes. The last one is similar to a 2-stage LFO. Shown controls will adapt to the selected mode, with Threshold not appearing while in Envelope Follower mode.
The modulation matrix has three general purpose modulation slots, and yes, you can select shake as one of many targets to modulate the Twang control!
Low Frequency Oscillator
The LFO features different time bases, including a non-synchronized one measured in seconds. Synchronized options include both dotted times and triplets. There are 8 different waveforms to choose from, with 2 of them being stepped or glide random shapes.
Modulatable, featuring 3 different reverberation tanks
In four different flavours
- LFO with 8 different waveforms
- variable time base
- variable type blend
- pre- or post-tank routing
- stereo offset
