Don't listen to those other guys......The one pedal you really should get is the Radial Engineering ToneBone-CLASSIC or BRITISH. Classic is based on vintage tonality of early Fender tube style amps,British based on early Vox AC30 and Marshall styles. Try them both, but heres the goods. They are both AC power only using a real 12AX7 tube. You'll be able to dial in just about any sweet tone you've ever heard and loved.......not kidding! Theses are not for the faint of heart price is around $300 but why by 2 or 3 different ones when one will do.Go to Harmony Central and check out the reviews,these are used by Eric Johnson,Steve Lukather and so on.
