"Loving it!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I haven't learned but about 40 percent of what this unit is capable of as it has many features. The controls on board give a lot of flexibility. Whether you are a newbie or have been around the Horn I feel this pedal is worth more than it costs, way more in fact. Build quality is very good and it seems quite rugged. I set all controls on my amps to flat response and adjust the curve with the onboard tone controls.
Musical Background:
Two US Navy bands, 20 years in show bands , jazz, rockabilly, original compositione and whatever strikes my fancy.
Musical Style:
Rock, jazz, rockabilly, country, jazz and originals
