Tokyo Tube EQ

Developer London Acoustics has introduced a plug-in for Acoustica Audio’s free Acqua N4 host. It’s called Tokyo Tube EQ, and is based on a rare parametric tube equalizer by an Italian manufacturer. It has four EQ bands — two shelving EQs and two fully parametric. Additionally, there’s a tube preamp emulation with medium and high saturation options.


There are input and output gain meters on the sides, as well as Bypass and Pre On/Off buttons. Gain can be controlled via the Trim pot on the input stage and the Volume knob on the output. The EQ section includes Low, Mid Low, Mid High, High knobs with adjustable frequencies for the Mid Low & Mid High bands. There are three adjustable Q shapes for the Mid Low and Mid High bands as well.

Overall, this seems a very decent and competently engineered EQ that’s certainly worth a try if you like the sound of tube equalizers.

Price and availability

Until the 24th of May, Tokyo Tube EQ is being sold at an introductory price of EUR 59.50, down from EUR 70. It runs under macOS and Windows in VST2, AAX, and AU formats. A free trial version is available, fully functional for four weeks.


For more tube equalizing fun, check out the VT-5 and Azure, both from Acustica Audio.
