Smooth Hound Innovations is a small privately held music electronics company in the UK, and SIVA Plugz is its series of virtual analog effects plugins for digital audio workstations. Based on the information on the page, it mainly offers guitar and bass amplifier models, positioning it more as an amp/cab simulation tool for recording, arranging, and mixing rather than general-purpose design software.
The main selling point of SIVA Plugz is “component-by-component, node-by-node” raw circuit simulation. The company emphasizes that this approach can deliver more realistic tone and distortion characteristics across different control settings and guitar/bass volume ranges. The amplifier plugins also include a cabinet simulator and input/output VU level meters. In terms of formats, they support AU and VST3, covering macOSX and Windows, making them suitable for hosts such as Logic, Cubase, Studio One, Reaper, and others that support these formats. Note that the Windows installer may trigger a Defender warning; the company says it can be ignored and that it is working on the certificate issue.
Pricing is based on one-time purchases per product. Most plugins listed on the page are priced at £24, £29, or £34, and a Free trial is available. The site also shows up to 50% off, plus a 5% discount for every £20 spent, valid for 12 months. Payments are processed through PaymentSense and PayPal, and the site states that it does not receive card details. The copyright terms are relatively strict: the software, website content, images, and marketing materials are owned by the company or used under license, and may not be copied or modified without permission. However, the main text does not specify plugin activation methods, the number of allowed devices, transfer policies, or similar licensing details.
The advantages are transparent pricing, trial availability, support for mainstream plugin formats, and models focused on classic guitar and bass amplifiers. This makes SIVA Plugz suitable for guitarists, bassists, independent musicians, and mixing engineers looking for traditional amp tones. The downsides are a limited library size—the page shows around 11 amplifier plugins—and no visible information about a preset cloud library, team collaboration, volume licensing, or Chinese-language support. The Windows certificate warning may also make some users more hesitant to install it.
The main text does not provide information about access from mainland China, RMB billing, or localized support, so this remains unknown. If access, payment, or installation is restricted, alternatives to compare include AmpliTube, Guitar Rig, Neural DSP, Helix Native, Scuffham S-Gear, or the amp simulators built into your DAW.
