Stone Deaf QBoost Vintage and Modern Frequency Booster Pedal

Vintage and modern frequency booster pedal for guitar or bass that does everything from transparent frequency boost to saturated overdrive and "dying amp" fuzz


Product Description

Give your guitar or bass rig a boost. The Stone Deaf QBoost does it all – from transparent frequency boost to saturated overdrive and ‘dying amp’ fuzz. Studios, stages, and bedrooms. It works wherever you need it to, making good tones great.

There’s no secret recipe for great tone, but the QBoost comes pretty close. Whether you’re looking to drive your amp harder, deliver more punch to a favorite pedal, or stand out for a solo, it’s the Swiss army knife you need to get the most out of your set-up.

The secret to the QBoost’s flexibility are the two sides to the circuit. As a pre-amp, you can toggle between vintage and modern voices, for always-on saturation, overdrive, and fuzz (vintage), pristine cleans (modern), and a whole world of sonic possibilities in between.

Whatever mood you’re in, the QBoost brings enough extra gain to the party to help you push pedals and amps to the limit, unlocking new, unique tones, and the creamy, magical saturation we all know and love.

If that wasn’t enough, the QBoost also showcases Stone Deaf’s love of guitar and bass EQ, with a built-in frequency booster that runs from 35 Hz to 6 khz. With a natural, medium Q factor, this lets the pedal emphasize a specific frequency when the second footswitch is engaged. Forget about a normal treble boost pedal. The QBoost lets you show off the highs, the mids, or the lows, to make sure your sound always suits the situation.

All of these features add up to make the QBoost a one-of-a-kind tone shaper. One that works interactively with your gear to take things to the next level and keep you, and your audience, wondering what’s coming next.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
