The Snarks are fine for tuning onesee-twosees and I generally look to them when on acoustic, but the HT-6 has been indispensable when running through an amp. Running the EVH through this box, and having the precision tuners to dial things in, the HT-6 is perfectly suited to tune the entire guitar in seconds. The foot switch cuts off output signal for tuning in isolation regardless of the ambient noise level. The display is easy read and I love that the full spectrum is displayed. It is worth noting that the HT-6 can also accommodate alternate tunings; however, my Musicman is a PITA when it comes to modified tuning on the fly so I don't use the feature. ~m
NOTE: After time, I've had the center LED drop out on the C chord. I can still tune, but obviously the pedal has some issues.
