I've recently tried a number of effects, looking for the one that would restore the joy to living. Tried a Pod. Tried a Digitech BP-50. Most recently I tried a E-H Bass Microsynth and a Digitech Bass Synth Wah. For me, there's no comparison. The E-H kills. Sure, it's 4 times more money, but I couldn't find any good sounds on the Digitech. I mean, they were good, I guess, but not usable for me. All were too extreme. The E-H on the other hand, can get extreme, but subtlety abounds. Plus, I got mine used from a fellow TB'er. The big advantage of the E-H is control. Start freq, stop freq, sub-octave, octave, square wave and so on are all individually controllable. Programmability would be nice, but being able to tweak all these things individually makes up for that (for me, anyway). And the sound. I used to pooh-pooh the idea that there was a really appreciable difference between analog and digital effects. But for me, the Digitech is too clean. The E-H box has a friendlier sound IMO. Plus, with the E-H, you can blend the dry and effected sound, which would require some sort of mixer with the Bass Synth Wah.
