Plugin Boutique is offering PSP Wobbler, a modulation effect plugin from PSP Audioware, at 50% off for $49 USD until April 25th, 2026.

This plugin recreates the sound of the Frequency Translator, a handmade experimental device built by Keith Adkins and used by Alan Parsons on Pink Floyd’s “Time” from The Dark Side of the Moon. Developed in collaboration with Parsons, it uses frequency shifting to create non-harmonic phase differences that produce a unique “wobble” effect incorporating elements of phasing, flanging, and a rotating speaker feel.

PSP Wobbler extends beyond the original hardware with features like controllable Drive, Ageing, Drift, and Spread, plus tempo sync and a pair of EQ filters to shape the effect’s frequency range. It supports VST/VST3, AU, and AAX formats for both Windows and Mac.

Music producers, recording engineers, and musicians seeking distinctive modulation effects for their tracks would find this plugin useful.

This deal allows access to a plugin rooted in historic recording techniques at half the regular price during the limited window.

More details are available on the PSP Wobbler product page and the PSP Audioware page at Plugin Boutique.
