Wampler Pedals are Made in the USA

Over the last couple of years Wampler Pedals have released the Black '65 and Tweed '57 to compliment the Plexi-Drive in the Heritiage Series. Having mastered the classic American tones from both the Blackfaced amps of the 60's and the Tweed style of the 50's, Brian decided it was time to concentrate on the other classic British tones...

The amps in question are renowned for their bell like quality and brilliance of clarity, these are the tones that have been the cornerstone of many famous musicians. Bands that have endorsed these classic tones are: The Beatles, U2, country artist Brad Paisley, The Shadows, and of course, the man with the most unique guitar tone of them all - Dr. Brian May of Queen.

Finally after tweaking this pedal for 3 years, Brian was beyond happy. Other pedals have come and gone, but this one has always been on the breadboard; being tweaked here and modified there. Finally Brian was ready to present one of his favorite tones of all time.

What makes those amps so special? Well, first of all there is the “chime” - A beautifully clear and concise high response that cuts through anything. Then there is the overdrive. When you push it hard (with the boost switch activated) the tone creates a midrange hump that makes your tone enormous but with enough clarity to hear every string ring through. The Ace Thirty truly is a master class in tone.

As you would expect from Wampler Pedals, great care has been taken to ensure authenticity of tone. The EQ features a Top Cut (not an inverted treble boost), that reacts and removes the same spectrum of frequencies you would expect from the originals. Switchable gain stages allow you a much clearer tone right up to the “that” beautiful, almost regal overdrive. On the inside is a trim pot that will adjust the input gain; so if you are using a guitar with hotter pickups, dropping this back a touch will allow you to retain a true clean tone. Brian has taken his time to ensure that this pedal is “just” right.

With the built in Class A treble boost, this really is the ultimate pedal of it's kind.

I'm not usually one to believe in the whole "amp-in-a-box" craze, but these guys have pretty much nailed it! Trying out this (along with their others in this series) through a Blues Jr., I was able to recreate my usual AC30 tone to a "T". It's dynamically responsive, and has the same brightness and sparkle that I'd expect. The wattage/headroom switch is a great feature, too.
