B.K. Butler Tube Driver (Mantovani Mod)

A few captures of my glorious BK Butler Tube Driver at different gain settings (low, medium and high). I also include the celebrate EricJohnson setting for his "violin tone". Sweep signal straight to the pedal and back into the DAW via a Universal Audio Apollo Interface. wave files were normalized to -18 dB LUFS before upload. This tube driver is a roughly 2015 model bought from the man himself and subsequently modded by Massimo Mantovani. The mod removes the bias knob, makes the pedal run from an 18 V pedal power outlet (300+ mV) and replaces some internal parts that make the pedal less sensitive to impedance issues as well as reduces the noise floor. Pete Cornish praised this work on several occasions.
