Shin-ei B1G 1 review on pedal-of-the-day.com

The Shin-ei B1G 1 Transparent Gain Booster delivers impressive studio-quality sound in a compact package. With a staggering +30dB boost, it enhances your tone without unwanted coloration, making it versatile for guitars, bass, and more. Built from robust materials, this pedal is as durable as it is effective. However, its single knob design may leave some users craving more control over their sound. Overall, it's a solid choice for those seeking straightforward, high-fidelity boosting.

We are honored that guitarist extraordinaire Julian Lage, has been using our B1G 1 Preamp Gain Booster on tour. He was kind enough to take a minute out of his day to send a message about his experience with the B1G 1. Here's what he had to say: "The B1G 1 pedal has quickly become a staple of my live set up. This is one of the most insantly useful pedals I’ve ever encountered - it essentially adds warmth and top end to the sound, all in a unified way, revealing what is coming from the guitar without ever feeling overly hyped. I am so fond of this pedal because it highlights and brings forth so much of what I love about the electric guitar, namely overtones and a wide dynamic range. Regardless of what amp I use the B1G 1 with, it seems to function almost like the mastering stage of an album - it is subtle and instantly musical, and when its not there, you sure miss it!" Thanks Julian!!

"I love my Vibe-Bro because I think it does complete justice to the old school vibe tones from the 60's. It's very analog sounding, and has some really innovative modern day features like the Bypass-Preamp setting. Shin-ei has literally nailed that classic vibe tone!"
