You know how it goes... Went into GC to get some picks and strings, and walked out with two pedals. They had a used Hardwire TR-7 (Tremolo/Rotary) that I tried out and really dug...lots of great sounds to find in that pedal. Then, when I was trying to decide whether to buy it, the guy (sales manager) pulled a Seymour Duncan Shape Shifter off the shelf and said, "we've got a deal on these...$69 bucks"!!! I guess they're running some promo with them right now, cuz that's pretty cheap. So, yeah... I bought both of them. The Shape Shifter is a great pedal...straight up analog tremolo with tap tempo, waveform adjust, and a tweak knob that allows you to sort of bias the wave to a fast or slow attack. It sounds beautiful paired with a TC Electronic HOF verb through the blues junior. The TR-7's tremolos have a little too much of a digital edge to them, with the exception of the bias trem setting(models a vox tube bias trem) which is pretty nice and well-rounded. But man, the TR-7 nails the Leslie sound on the Rotary setting and does a pretty good Vibe too. If you can pick one up used, it's worth it for the Rotary alone.
