I've had one for about 2 weeks and it really is as good as the Youtube reviews are. Then again, most of those reviewers would sound impressive through a solid-state stereo amplifier -with a cereal box for a speaker. That said, it really is as good a pedal as everyone on Youtube raves. After playing it through a couple of band practices though, I wish it had a dedicated "bass" control of some sort. I've owned and gigged with a number of blackface Fender amps and like many other folks, I've always kept the bass somewhere around 2 to 3 on the bass knob. This is a fabulous pedal, but it seems they hardwired that setting into the circuit. Does it sound like a blackface amp? Quite so. However, to my ears it has a bass cut as prominent as a Tubescreamer pedal. Is it still useable? Yes. Does it sound good? Oh my...yes. Would I rather have been able to dial in the bass setting to taste? Depending on which guitar I switch to during a gig....yep. The brownface setting of the pedal comes pretty close to my old '62 Deluxe (that I stupidly sold back in the 90's) and doesn't have quite the bass shelving that the BF setting does. If I had any idea how to mod the pedal, I'd do so simply to gain back a touch more low end in the BF setting. ****e, the pedal is so good, I'd be willing to scar it up and put in a mini-bass pot if I knew how! Anybody know if this circuit is close another existing effect pedal???
