Wampler DB+ Boost/Buffer Pedal Review (July 2024)


Last updated on July 22, 2024 8:53 pm Details


In this review post, we’re going to be discussing the Wampler Decibel Plus V2 Boost & Independent Buffer Guitar Effects Pedal, including an overview of its unique features.

Product Description

All great guitar tones have a solid foundation. Too many cables going in and out of your pedalboard and to and from your amp can sometimes accidentally rob of you your guitar’s natural higher frequency tones (making your tone muddy) and in essence – create “tone suck”. A quality buffer can help prevent those high frequencies from being lost and with a clean boost – you can make sure your guitar always sits in the mix. Introducing the Wampler dB+.

The dB+ has all the same great features as its predecessor – the Decibel + – but now you have the ability to turn the buffer on and off independently as well in a now micro pedal size. Whatever your needs may be, the dB+ is ready to deliver. From studio or stage, it’s a one-knob problem solver toolkit.

You no longer have to suffer high-end signal loss, or “tone suck” again. You never have to have your boost on just to have your buffer on. You can now take ownership of your tone and have it exactly as you want it at all times.

Our Verdict

This pedal functions as both a buffer and a boost for your sound: in addition to restoring signal strength, it allows you to increase the volume of your playing when turned on.

This stompbox has a “Boost” button that lets you determine how much enhancement you want, as well as a led light that indicates when the buffer is active: when used to boost the guitar’s sound, it also adds a little more color to your sound, giving your riffs and solos even more life.

When used solely to buffer the signal, it remains quite crisp and does not modify much of the sound.

Where to Buy

The best place to buy this product has to be Amazon, due to their competitive pricing and fantastic customer service.
