is the Radial Tonebone Classic equipped with a 12AX7 vacuum tube,
this pedal blew me away when i first played through it.
It was the first time i actually heard creamy tube tone.
This pedal is fantastic for John Petrucci, Andy Timmons type lead-tone.
It is extremely versatile with the "top end", "mid boost" & "drive gain" settings available to tweak to your desired sound.
It is no doubt one of the top tube equipped pedals out there.
