From the post
Info about the original:
The Wampler Tweed 57 is the heart and soul of a mids 50s Fender Tweed amp. Just think Eric Clapton playing Layla: that tiny Fender pushed to the absolute limit for that crunchy yet 100% Fender tone.
We all know that when you need a pedal that nails the sound of an amp there's only one place to turn: Brian Wampler obsessively A/B tests his boutique pedals with the real deal to make sure that the tone is nailed, especially the details that other amp emulators miss like the way the overdrive reacts to gentle playing or rolled off volume/tone.
As well as EQ and Gain controls the Wampler Tweed 57 features an input simulator, an important detail for getting the authentic fender sound!
