I have a digitech RPX 400. I love it it has just about every effect imaginable. You can even use it as a recording interface via USB with your computer. It cost about $300 (US). You can find out more at www.digitech.com
. I play with it on my 10 watt marshall amp and for live performance you can plug it directly into the PA system since it is also an amp modulator. I use both my Strat and Les Paul with it. They both sound great. Check out what Lyle uses; it sounds great. Digitech offers a variety of products more advanced and less advaced as well. I suggest going to your local guitar shop and plugging your favorite guitar into as many different ones that you can and choose the one you like best. Make sure you use an amp similar to yours.
