Fulltone Soul-Bender

according to Mike Fuller at Fulltone,

"Our Soul-Bender is based on the legendary Colorsound and Vox Series III ToneBenders made by Sola-Sound/England in the late '60's that was used by Beck and Page on much of their circa 1968-70 recordings.

Equipped with 3 gain-matched germanium transistor for a FAT, searing lead tone, I've improved on the original by adding an internal trimmer allowing you to reshape the distortion from Rich legato sustain to bombastic all-out square fuzz. I also made the Tone control response and range more usable and much less shrill sounding...
Full clockwise is SMOOTH sounding.

The Soul-Bender cleans up when you back-off on the guitar's volume control. This pedal has tons of tonal character and even harmonics and of course, true bypass w/ LED is included with every one."

Prescription Electronics Yardbox

according to Prescription Electronics,

" A faithful sonic copy of the original Sola Sound Tonebender, purportedly the only distortion pedal used on Led Zeppelin's first two albums. The pedal has no similarity to Jumbo, Supa, or the Vox Tonebender. Wide variation in tone and smooth dynamics at all volumes."
