When running it through its paces here at GearNuts, we found that the WA-1B not Review: Warm For Sure! - Love it!! Review: Delish - Is it exactly the same as the original? Without having them side by side, I can never know. However, my friend has the TubeTech, and I can tell you that my vocal takes and his both sound great and I don't hear anything that makes me think I'm using an inferior compressor. I regularly hit mine hard and it performs admirably well for vocals, bass guitar and voiceover. It's my number one, goto comp - and I have a Distressor, Fatso, six 1176's, 2 LA-2A's, a Manley Elop, a Neve Portico - I could go with any one of those but the WA-1B just works so well and the compression works so well that I don't feel like it takes away from the performance. The others are all amazing in their own ways but sometimes I just want something that elevates my performance and doesn't take my attention away from it. Try hitting a vocal hard with an 1176 - you will notice it - it pulls you away from the track. I dunno. I really like my WA. Keeping it. ## Features - 1-channel Tube Optical Compress ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CKTM2QB3 | | Amperage | 9 Milliamps | | Audio Output Effects | Compression | | Best Sellers Rank | #107,628 in Musical Instruments ( See Top 100 in Musical Instruments ) #31 in Effect Processor Compressors | | Brand Name | Warm Audio | | Connector Type | 3.5mm Stereo Audio Jack | | Controls Type | Knob | | Customer Reviews | 3.4 3.4 out of 5 stars (6) | | Global Trade Identification Number | 00850031640238 | | Hardware Interface | HP-HSC | | Included Components | Rackmount Chassis, Compressor Unit | | Item Dimensions | 27.5 x 18.45 x 5.7 inches | | Item Weight | 12.1 Pounds | | Manufacturer | Warm Audio | | Manufacturer Part Number | WA-1B | | Model Name | WA 1B | | Model Number | WA-1B | | Power Source | Corded Electric | | Set Name | WA 1B | | Signal Format | Analog | | Style | Portable | | UPC | 850031640238 | | Voltage | 9 Volts | ## Product Details - **Amperage:** 9 Milliamps - **Brand:** Warm Audio - **Item Weight:** 12.1 Pounds - **Style:** Portable - **Voltage:** 9 Volts ## Images ![WA-1B Optical Compressor - Image 1](https://m.media-amazon.com/images/I/51L9MUV5XsL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Warm For Sure! *by K***S on May 4, 2025* Love it!! ### ⭐⭐⭐⭐⭐ Delish *by J***B on April 17, 2026* Is it exactly the same as the original?
