From the manufacturer:
A full frequency boost and independent buffer brought to you in a small footprint mini pedal.
All great guitar tones have a solid foundation. Too many cables going in and out of your pedal board 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 – creating “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 it’s 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.
